INTRODUCTION

Improper human practices, such as the haphazard usage of chemicals, increased utilization of non-renewable energy sources, and unrestricted production of industrial waste, have represented a great threat to environmental sustainability.[1] Therefore, there are intense efforts to adopt cleaner production, sustainable measures, and green technology.

The UN adopted the Sustainable Development Goals (SDGs) for world’s sustainable economic development.[2] SDGs include five subcategories: partnerships, people, planet, prosperity, and peace. SDGs seek to create solutions for promoting societal and financial development without compromising the environment, emphasizing environmental protection by stopping and regulating the use of natural resources.[3]

Fungi comprise a significant part of the biological biodiversity, with an estimated number of 2.2–3.8 million species that demonstrate a marked capability to adapt and flourish in harsh niches and climatic fluctuations, supporting environmental sustainability.[2,4] Fungi can be effectively and purposefully utilized for bioeconomy, as they can minimize global climate change, tackle food security challenges, and secure a low-carbon economy.[5] Fungal enzymes account for more than 50% of the total enzyme market and are used instead of chemical processes in several industries, such as leather, textiles, paper, pulp, food, feed, brewing, baking, and detergents, which remarkably minimize negative influences on the environment and CO₂ emissions.[5,6]

Extracellular enzymes of Aspergillus allow them to modify their metabolism in response to different sources of carbon and nitrogen.[7,8,9,10] These extracellular enzymes are highly relevant to the biotechnology sector because of their distinct enzymatic functions; however, they also undoubtedly contribute to infection or act as allergens in pathogenic organisms. A. fumigatus saprophytic fungus utilizes the vegetative mycelium growing in soil to produce asexual spores. It causes intrusive fungal infections in immune-deficient patients, including chronic pulmonary aspergillosis, which is one of the most common invasive fungal illnesses in these patients.[11] On the contrary, A. fumigatus has the capability to biosynthesize different classes of secondary metabolites with a range of bioactivities and agricultural uses.[9] On our continuous interest in shedding light on the potential of Aspergillus species, this review focuses on A. fumigatus’s industrial, pharmaceutical, and biotechnological importance as well as its value in bioremediation and environmental sustainability. This work points out the need for further studies to effectively and safely profit from the potential of A. fumigatus, which although being pathogenic provides intriguing possibilities for ecologically friendly industrial processes.

METHODOLOGY

A comprehensive search was carried out utilizing a variety of sources, including PubMed, Scopus, ScienceDirect, and Google Scholar. All the published works (books, research papers, and review articles) relevant to A. fumigatus biotechnological uses, enzymes, and nanotechnological and industrial applications were included. The search keywords included “Aspergillus fumigatus + biotechnology,” “Aspergillus fumigatus + enzymes,” “A. fumigatus + nanoparticles (NPs),” “A. fumigatus + bioremediation,” “Aspergillus fumigatus + sustainable development,” and “Aspergillus fumigatus + biotransformation.” All the reported works on the applications of A. fumigatus in the period from 2020 to 2024 were included.

Nanotechnological applications

NPs are synthesized using various physical and chemical methods, some of which are extremely expensive and involve the use of hazardous, toxic chemicals, posing potential risks to human health and the environment.[12] Consequently, the green synthesis of NPs using plants, fungi, bacteria, algae, and their metabolites has gained attention as a cost-effective, less toxic, and eco-friendly alternative technique.[12]

Studies have shown that A. fumigatus is an excellent candidate for intracellular or extracellular biosynthesis of NPs with variable sizes. The reported studies on the use of A. fumigatus in NP synthesis and the biological activities of these NPs are summarized in Table 1.[13,14,15,16,17,18,19,20,21,22,23,24,25,26]

Silver nanoparticles

Kalyani et al. reported the synthesis of stable AgNPs (size: 1–20 nm) employing aqueous Ag + ion reduction with A. fumigatus culture supernatants at room temperature, tracked using UV-vis spectroscopy, transmission electron microscopy, and X-ray. Interestingly, these NPs exhibited broad-spectrum activities against various pathogenic bacteria and fungi, suggesting their potential use alone and/or in combination with antibiotics to control multidrug-resistant pathogen-induced infections.[13] Bhainsa and D’Souza reported the extracellular synthesis of AgNPs (size range: 5–25 nm) using A. fumigatus NCIM-9902.[14] Another study by Al-Abdullah also revealed that A. fumigatus AgNPs possess potent bactericidal and antibacterial capacities against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus obtained from surgical place wounds.[15] In addition, AgNPs were produced using A. fumigatus-derived from Cannabis sativa leaves, demonstrating antibacterial potential against human pathogens: Enterococcus sp., E. coli, Klebsiella pneumoniae, and Staphylococcus albus (inhibition zone diameter [IZD]: 14–20 mm).[16] A. fumigatus-AgNPs exhibited activity versus E. coli, P. aruginosa, S. aureus, and S. typi (IZD: 18–28 mm) in comparison to ciprofloxacin (IZD: 22–25 mm).[17] Saqib et al. synthesized and characterized AgNPs that showed notable antibacterial capacities versus S. aureus, S. dysenteriae, and S. typhi (IZD: 18.21, 16.18, and 14.41 mm, respectively).[18] These AgNPs were found to cause damage to the bacterial cell membrane and release cellular contents, specifically proteins and nucleic acids, resulting in bacterial growth inhibition.[18]

A study by Sarsar et al. demonstrated the activity of AgNPs against S. aureus, S. typhimurium, A. hydrophila, E. aerogenes, M. luteus, and B. cereus, with high efficacy against A. hydrophila and B. cereus (IZD: 20 and 22 mm, respectively).[19]

Shahzad et al. reported the biosynthesis of the smallest size AgNPs (size: 0.681 nm) with 100% monodispersity by using A. fumigatus BTCB10 under the following conditions: 25°C/1 mM AgNO₃/seven g biomass/pH 6/fungal culture age: 7 days/silver nitrate: cell-free filtrate (2:3)/20% NaCl under dark light.[20] These NPs exhibited antibacterial effectiveness against multidrug-resistant bacteria, including K. pneumoniae BTCB04, Acinetobacter BTCB05, P. aeruginosa BTCB01, and E. coli BTCB03, being 7-fold more active against Acinetobacter BTCB05. They were inactive against HepG2 cells; however, their combination with cisplatin boosted the cytotoxic effects.[20]

A study by Zomorodian et al. reported the relationship between AgNP production and nitrate reductase activity.[24] The AgNPs synthesized from A. fumigatus MTCC-11399, either alone or in combination with chloramphenicol, demonstrated notable antimicrobial potential versus E. coli, K. pneumonia, B. cereus, S. aureus, and Streptococcus sp.[21]

Gold nanoparticles (Au NPs)

Bathrinarayanan et al. reported the synthesis of stable Au (gold) NPs (size: 85.1–210 nm) through the reduction of HAuCl₄ (chloroauric acid) aqueous solution by A. fumigatus' biomass, which was characterized by FTIR, SEM, EDS, and XRD.[22] Further, intra and extracellular syntheses of AuNPs by SBS-3 with sizes of 26.16 and 17.76, respectively, were also reported.[23]

Copper oxide nanoparticles

CuO NPs were synthesized and characterized by Ghareib et al. using A. fumigatus Fresenius AUMC-13024 mycelium. They have a mean size of 6 nm and retain complete stability at 4°C for 6 months on storage. The maximal yield was obtained at pH 6/30°C/Cu (NO₃) 2.3H₂O 1mM/after 60 h-shaking at 150 rpm in the dark. These NPs demonstrated antibacterial potential versus S. aureus and K. pneumonia (MIC: 50 and 60 µg/mL, respectively). In addition, these NPs decolorized 97% methylene blue dye after 200 min in direct sunlight.[24]

Zinc oxide nanoparticles

The ZnO-NPs biosynthesized using A. fumigatus JCF, obtained from vegetable wastes, showed significant antibacterial potential versus S. aureus and K. pneumonia.[25] This effect was attributed to the formation of highly reactive species that damaged the bacterial cell walls.[25] Additionally, monodisperse ZnO-NPs synthesized using A. fumigatus TFR-8 were found to be suitable for plant nutrition.[26] The application of these NPs (concentration: 10 ppm) resulted in marked enhancement in root-shoot growth, chlorophyll content, rhizospheric microbial population, total soluble leaf protein content, and P-mobilizing enzymes (acid and alkaline phosphatases and phytase) in 2-week-old cluster bean plants. In addition, their application remarkably improved the gum content and viscosity of cluster bean seeds, highlighting the possible usage of these NPs as bio-nano-fertilizers for plant nutrition.[26]

Biotechnological and industrial applications

Industrial fermentation

Microbial fermentation technology has been shown as a very feasible and prospective approach for taxol production in large amounts. Various taxol-producing fungi have been reported to produce taxol; however, some of them yielded taxol in low amounts, making them unsuitable for industrial production.[27]

Among the 34 fungal isolates screened from Taxus species collected in Shimla, Himachal Pradesh, India, A. fumigatus demonstrated the highest taxol production, yielding 1.60 g/L. This finding highlights A. fumigatus as a promising and valuable microbial source for the commercial-scale production of taxol.[28]

Biotransformation

Taxifolin is a multifunctional food additive with multiple biological properties. It is obtained by extraction from larch wood; however, the yield (1%–2%) is relatively low. It can also be synthesized or semi-synthesized from catechin; the synthetic taxifolin is more costly and of lower purity than the natural one.[29]

It was found that A. fumigatus SQH4 isolated from Smilax glabra rhizome bio-transformed astilbin (taxifolin-3-O-rhamnoside) to taxifolin through deglycosylation.[29] A 91.3% yield of taxifolin was achieved with 5 g/L astilbin at pH 6.5/35°C after 14 h. Therefore, this could be an alternative potential method for the large-scale production of taxifolin for the food industry.[29]

Bioremediation

Fungi-dependent bioremediation is an auspicious technological avenue that is both cost-effective and efficient. It is more favorable to bacteria-based bioremediation because of their hyphal network, biomass, and longer life cycle.[30] Detergents, antibiotics, heavy metals, plastics, herbicides, polyaromatic hydrocarbons, and insecticides are successfully degraded by employing myco-remediation.[30]

Biomass bioconversion

Cellulases

The lignocellulosic materials’ bioconversion is a substantial source for producing biofuels and biochemicals to achieve a circular economy and counteract the greenhouse effect. Cellulose is the most plentiful natural polysaccharide in the lignocellulosic biomass. Cellulases include three main enzymes, namely β-glucosidase, β-1,4-endoglucanase, and β-1,4-exoglucanase, which act synergistically for the efficient hydrolysis of cellulosic biomass.[31] Cellulases offer wide industrial applications in different fields, including detergent, beverage, and biofuel industries.[31]

The treatment of thermostable cellulase secreted by A. fumigatus AA001 with ZnO-NPs boosted its thermal stability for 10 h at 65°C and maximum alkaline stability at pH 10.5, retaining 53% of its activity.[31] This was suitable for application in biohydrogen and bioethanol production for cellulosic waste bioconversion in an eco-friendly method.[31]

Das et al. reported that the usage of Box-Behnken response surface methodology along with Plackett-Burman factorial design optimized the production of xylanase and cellulases by A. fumigatus ABK9.[32] It was found A. fumigatus ABK9's cellulolytic enzyme production was increased by more than 1.3 folds on using optimized medium containing rice straw: wheat bran (1:1) as substrate. These enzymes efficiently deinked laser-printed paper wastes within 6 h and could serve as a cheap effective catalyst for deinking of waste office papers.[32]

Glucosidases

Kim et al. established a proteomics strategy to discover β-glucosidases in A. fumigatus by using secreted proteome 2DGE and LC-MS/MS. Two novel β-glucosidases were characterized, and the EAL88289 gene of one of them was cloned and heterologously expressed.[33] The expressed enzyme had greater heat stability compared to those of A. oryzae and A. niger.[33] The improved thermal stability allows quick cellulose hydrolysis processes, hence reducing the cost of producing bioethanol.

A novel β-glucosidase was purified by Yamamoto et al. from A. fumigatus AP-20 isolated from soil in Aichi prefecture, Japan. This enzyme specifically cleaved p-nitrophenyl β-primeveroside into p-nitrophenol and primeverose.[34] β-Primeverosides have a substantial function in aroma generation in black-tea manufacturing.[34]

Monooxygenases

Monooxygenases are AA9 family members that assist hydrolytic enzymes in polysaccharide depolymerization.[35] Velasco et al. characterized AfAA9C, a new lytic polysaccharide monooxygenase (LPMO), from A. fumigatus that oxidized glucose residues in the cellulose chain at C1 and C4 carbons. This enzyme is light-activated and active on xyloglucan.[36] AfAA9C’s affinity fluctuated depending on the association of the reducing agent with the photosystem, due to the formation of H₂O₂, suggesting its significant implications in photo-biocatalytic reactions and sustainable commercial processes such as biomass depolymerization.[36]

Galactanases

Exo-β-galactanases, β-galactosidases, and endo-β-galactanases are the principal enzymes accountable for the degradation of arabinogalactans.[37] These enzymes have a vast variety of applications, including cellulose pulp bio-bleaching, arabinogalactans bioconversion to fermentable sugars for ethanol production, pectin property modulation, arabinogalactan’s structure determination, and improving animal feed.[38]

A (1→3)-D-galactanase was isolated from Aspergillus fumigatus No. 232, associated with coffee beans. This enzyme hydrolyzed arabinogalactans from coffee beans, Gum Arabic, curdlan, and larch wood, substrates containing α-(1→3) and β-(1→3) linkages into galactose, arabinose, and galactobiose. Its optimal activity and stability were noted at pH 4.6/45℃ and pH 4.0/50℃, respectively; however, it was inhibited by Hg⁺².[37]

Chitinases

Chitin is a key structural element of the cell walls of many organisms. Chitin’s resistance to breakdown has led to numerous issues in agriculture and industry; as a result, there is now greater interest in chitinases, enzymes that hydrolyze chitin.[39] Chitinases are enzymes that break β (1–4)-linkage between the N-acetylglucosamine residues in chitin and are utilized in many different industries such as the production of GlcNAc and chitooligosaccharides, waste management, tannase recovery, and as a biocontrol agent.[40]

A. fumigatus df347, a chitinase-producing strain, was isolated from the mangrove wetland sediment/Guangxi Zhuang Autonomous Region that inhabits the intertidal zone of the subtropical coast, which is characterized by a high temperature and salt content (about 2% NaCl).[41] Its AfChi28 chitinase gene was characterized and heterologously expressed in Escherichia coli, producing a bifunctional enzyme, AfChi28. This enzyme is resistant to temperature changes and acido-halo tolerant and cleaves both exo and endo molecules with 52.414 mU/mg activity.[41] A. fumigatus CS-01 derived from water and soil obtained from the south central region produced chitinase with 0.118 U/mL maximal activity at 55°C/pH 5 and stability below 45°C/pH 4.0–7.5.[42]

Starch hydrolysis

Amylo-glucosidases

A significant amylolytic enzyme, amyloglucosidase produces D-glucose by sequentially working on the α-(l→4) and α-(1→6) links of the starch molecule.[43] The released glucose is utilized in several industries, such as food, pharmaceuticals, textiles, ethanol production, baking, and brewing.

Pervez et al. reported that the cross-linking of A. fumigatus KIBGE-IB33 amyloglucosidase by employing a carrier-free strategy improved the enzyme’s catalytic potential as well as storage and thermal stability.[43] Additionally, there was an eightfold rise in glucose production compared to soluble amyloglucosidase. Hence, the carrier-free technique is more efficient for continuous starch hydrolysis and glucose production.[43] A study by Song et al. revealed that mutation of A. fumigatus raw starch glucoamylase by N-glycosylation introduction and recombinant expression in Komagataella phaffii produced three mutants with improved catalytic activity of raw corn starch.[44] Thus, the N-glycosylation site technique is an effective process for improving raw starch glucoamylase activity toward raw starch.

Detergent industries

Amylases

Amylases are potential enzymes in textiles, food, detergent, and paper industries.[45] Amylases are among the most significant enzymes in the enzymatic detergent formulation as 90% of liquid detergents contain these enzymes.[46]

Singh et al. reported that amylase enzyme produced by mutated and wild-type A. fumigatus NTCC-1222 strains displayed high compatibility with different detergent formulations and significant stability in hard water, indicating its possible use in detergent formulations in detergent industries.[47]

Proteases

Proteases are the most common type of enzymes due to their great use in a variety of processes, such as pulp, paper, dairy, and detergent sectors. About 60% of the enzymes that are sold commercially each year are proteases.[35] The global protease market was valued at 2.76 billion USD in 2019 and is estimated to grow by 6.1% annually from 2019 to 2024.[48]

In 1995, an elastolytic proteinase was purified and characterized from A. fumigatus-isolated allergic bronchopulmonary aspergillosis patient. It showed proteolytic potential as it hydrolyzed Lys (29)-Ala (30), Tyr (26)-Thr (27), Gly (20)-Glu (21), Tyr (16)-Leu (17), Glu (13)-Ala (14), Gly (8)-Ser (9), and Asn (3)-Gln (4) bonds of oxidized-insulin B chain.[49] Another study reported that among the five tested A. fumigatus strains, A-4-51 and A-4-38 strains remarkably produced protease in submerged culture using glucose-liver medium.[50]

Keratin is a compact polypeptide featuring strong disulfide bonds and other interactions, making its degradation difficult by proteolytic enzymes such as papain, trypsin, and pepsin.[51] Fungal alkaline proteases can degrade keratin, resulting in the production of useful products. These enzymes are also used in the food, textiles, leather, glue, and foil industries, as well as in the production of biodegradable films and nitrogenous fertilizers for plants.[51]

A study by Kim in 2003 reported the characterization of protease from A. fumigatus, which degraded chicken feather keratin.[52] Paul et al. reported the isolation of extracellular keratinase from A. fumigatus TKF1, obtained from the soil of a poultry waste site. This enzyme disintegrated whole chicken feathers and reduced disulfide bridges. It showed significant compatibility and stability with pH and temperature.[51] Feather degradation increased oligopeptides and free amino acids (threonine, cysteine, leucine, phenylalanine, isoleucine, and valine), as well as the production of phenylalanine and methionine as microbial metabolites.[51]

An elastase purified from Aspergillus fumigatus exhibited optimal activity at 37°C and pH 8.0, and its activity was inhibited by ulinastatin.[53] This enzyme infusion in the guinea pig trachea produced hemorrhagic pneumonia that was modulated by ulinastatin intravenous drip infusion along with hemostatic and antifungal agents.[53]

Lipases

Lipases are triacylglycerol hydrolases that catalyze the hydrolysis of long-chain triglycerides to fatty acids and glycerol.[54] They are used as catalysts in different fields such as organic chemistry, oleochemicals, pharmaceuticals, and biofuels.

Kaur et al. purified lipase from A. fumigatus using (NH₄)₂ SO₄/octyl sepharose CC with 14.34 Umg_-1 activity. This lipase (30 µg/mL) bio-catalyzed the synthesis of methyl butyrate through the transesterification using vinyl butyrate and methanol (2:2 molar ratio) in a medium containing n-hexane, with a maximum yield (86%) after 16 h of incubation at 40°C.[55]

Mehta et al. reported that A. fumigatus associated with oil-contaminated soil possessed good lipase activity after 72 h incubation at 45°C/10 pH using 0.1% peptone and 1% galactose as carbon and nitrogen sources, respectively.[56] The isolated lipase had optimal activity at 40οC/9.0 pH with p-nitrophenyl benzoate as the substrate that was prohibited by metal ions.[56] In another study, the same authors utilized the purified A. fumigatus lipase for ethyl lactate and ethyl acetate synthesis. The esterification of ethanol with acetic acid (molar ratio 1:1; 130 min_-1 shaking) at 40℃ for 12 h produced 89% ethyl acetate, whereas the maximum esterification of ethyl lactate (87.32%) was obtained using lactic acid: ethanol (100:500 mM) in heptane under 120 rpm shaking at 40℃ after 12 h.[57] Ethyl acetate is utilized in nail polish removal and decaffeinated coffee, tea, and cigarettes, as well as perfumes, cosmetics, and entomology products.[57]

Platelet activation

Platelets are multifaceted components of the immune network that play a crucial role in the innate immune response to several pathogens.[58] Galactosaminogalactan (GAG) is a fungal exopolysaccharide consisting of partially deacetylated N-acetyl galactosamine and galactose residues. The activity of the UDP-glucose-4-epimerase (Uge3) is required for synthesizing the sugar-building blocks of GAG.[58]

It has been reported that A. fumigatus and its metabolite (gliotoxin) activate platelets by secreting a serine protease[59] and by direct contact with the A. fumigatus hyphal cell wall, due to the hyphal-linked polysaccharide GAG that stimulates circulating platelets.[60] Additionally, significant pathogenicity factors, such as hydrophobin, conidial melanin, and hyphal GAG, can alter platelet function and may thus affect thrombosis, inflammation, and immunological responses in infected individuals.[60]

A study by Deshmukh et al. revealed that A. fumigatus culture supernatants caused powerful time- and dose-based stimulation of platelets. This relied on the production and deposition of the secreted GAG on the platelet surface.[61]

Dye degradation

Effluents are unwanted fluids, wastewater, and chemicals in liquid form discharged as wastewater from various industries, including dye, textile, leather, cosmetics, food processing, and paper.[62] Wastewater from the textile industry contains toxic and recalcitrant products that are difficult to degrade. It was estimated that about 280 thousand tons of dyes utilized in textiles are released into the environment globally every year.[62] Dharajiya et al. stated that A. fumigatus A23 effectively decolorized textile effluent by 86% under optimized conditions: potato dextrose agar medium/40°C/pH 4.0/100 rpm agitation after 7 days of incubation. Its mechanism involves adsorption and absorption of the dye.[63]

CONCLUSION

The present work illustrates A. fumigatus’s remarkable biotechnological and industrial importance, highlighting its different applications in pharmaceuticals, nanotechnology, bioremediation, and enzyme production [Figure 1].

Cellulases, lipases, proteases, and chitinases are some of the economically valued enzymes that the fungus has the ability to produce. These enzymes are crucial for environmentally friendly industrial processes, such as biofuel production, the degrading of waste, and the food and textile industries [Figure 2]. These enzymes’ alkaline stability and thermostability maximize their value in a variety of bioprocesses.

Figure 2.

Examples of Aspergillus fumigatus’s enzymes and their applications

A. fumigatus was found to play a marked role in bioremediation; it effectively degraded organic contaminants and industrial colorants. It possesses the capacity to transform lignocellulosic biomass into fermentable sugars for the manufacture of biofuel, demonstrating its promise in circular economy. Even with these encouraging uses, A. fumigatus is still a recognized human pathogen that primarily affects people with compromised immune systems. Its capacity to generate virulence factors, invasive conidia, and allergens presents health hazards that need to be properly controlled. Future studies should thus concentrate on maximizing its industrial and environmental uses, as well as genetic engineering to reduce pathogenicity while enhancing enzyme production.
