Different microorganisms and their bioaccumulation and biosorption capacity.
| Microorganism(s) | Contaminant(s) | Remarks | References |
|---|---|---|---|
| Scenedesmus acutus, Chlorella pyrenoidosa | Cd | C. pyrenoidosa and S. acutus accumulated 3 and 1.5% of Cd and biosorbed 97 and 98.5% of Cd, respectively. | Chandra et al., 2020 |
| Aspergillus spp. | Cd, Cu | The removal efficiency for Cu and Cd was recorded >90%. The biosorption potential of living and dead cells for Cd was 0.1977 and 0.1772 mg g−1 and for Cu it was 5.3676 and 18.661 mg g−1, respectively. | Hasgül et al., 2019 |
| Streptomyces K11 | Zn | The bioaccumulation capacity was 4.4 mmol g−1. The maximum biosorption capacity recorded was 0.75 mmol g−1. | Sedlakova-Kadukova et al., 2019 |
| Bacillus xiamenensis PbRPSD202 | Pb, Cd, Cr, As, Ni, Cu, and Zn | The maximum Pb biosorption capacity for living and dead biomass of B. xiamenensis shows 216.75 and 207.4 mg g−1, respectively. | Mohapatra et al., 2019 |
| Aspergillus flavus SFL | Cr | The intercellular accumulation of A. flavus SFL was 50% more than the reference strain. | Vajpai et al., 2020 |
| Phanerochaete chrysosporium | Cd+2, Ni+2 | The accumulation efficiency of P. chrysosporium for Cd2+ and Ni2+ was 96.23 and 89.48%. The maximum biosorption capacity for Cd+2 and Ni+2 recorded 71.43 and 46.50 mg g−1, respectively. | Noormohamadi et al., 2019 |
| Pseudomonas azotoformans JAW1 | Cd, Pb, and Cu | Metal accumulation occurs on the cell surface (biosorption). The maximum adsorption found of Cd, Pb, and Cu by 98.57, 88.57 and 69.76%, respectively. The removal level achieved the highest in order of Pb (78.23%), Cu (63.32%), and Cd (44.67%). | Choińska-Pulit et al., 2018 |
| Aspergillus tamari, Simplicillium subtropicum, Aspergillus niger, Fusarium solani, | Cu | Although A. tamari and S. subtropicum growth rate was low, the intake of Cu per unit of biomass is high compare to two other species. | Ong et al., 2017 |
| Ensifer adhaerens OS3 | Cd, Cr, Ni, Pb, Cu, and Zn | The maximum accumulation was recorded for Ni (95%) and lowest for Pb (74%) and in order of Ni > Cu > Zn > Cr > Cd > Pb. Biosorption capacity recorded in order of Zn > Cr > Cd > Ni > Cu > Pb. | Oves et al., 2017 |
