Entry | DES components | Organisms used for toxicity assay | Main results | Ref |
---|---|---|---|---|
1 | MTPB:gly MTPB:EG MTPB:TEG |
Gram(-): Escherichia coli and Pseudomonas aeruginosa. Gram(+): Artemia salina, Bacillus subtilis, Stapylococcus aureus, |
DES toxicity > components. DES showed anti-bacterial activity |
[98] |
2 | ChCl with U, OA, Xyl and Sor B with Glc, MA: PRO, MA:Glc, CA with PRO, Glc:gly, |
Gram(-): Escherichia coli, Proteus mirabilis, Salmonella typhimurium and Pseudomonas aeruginosa Gram(+): Staphylococcus aureus Candida albicans |
No inhibition of bacteria with ChCl:Xyl, ChCl:Sor and B:Glc ChCl:U was effective only against E. coli C. albicans was only inhibited by ChCl:OA |
[99] |
3 | CpA:LaA CpA:MyA CpA:SA |
Gram(-): Pseudomonas aeruginosa and Escherichia coli Gram(+): Staphylococcus aureus, Staphylococcus epidermis, Candida albicans |
No inhibition against Gram-negative Misleading results for Gram-positive bacteria and yeast due to the diffusion ability of the compounds and incubation temperature CpA:LA promoted biofilm detachment/removal in all microorganisms |
[101] |
4 | ChCl with amines, alcohols, sugars, and organic acids |
Gram(+): Staphylococcus aureus and Listeria monocytogenes Gram-(-) Escherichia coli and Salmonella enteritidis |
Toxicity of DESs containing organic acids: ChCl:A ˃ChCl:Levulinic acid(LeA) ˃ChCl:CA ˃ChCl:MA ˃ChCl: Malic acid (MaA)˃ChCl: tartaric acid (TA) ˃ChCl/p-toluenesulfonic acid (PTSA). | [102] |
5 | BC:AcA BC:McA Polymer BC:AcA and BC:McA |
Gram(+): Staphylococcus aureus Gram-(-) Escherichia coli Candida albicans |
Toxicity of monomeric DESs higher than polymeric AcA > BC:AcA > BC:McA > BC > McA for S. Aureus and C. Albicans Similar toxicity for E. coli |
[104] |
6 | Menthol:BA Menthol:PhA |
Gram-(-) Escherichia coli Gram(+): Staphylococcus aureus and Bacillus subtilis |
Similar MIC values for THEDESs. | [105] |
7 | ChCl with gly, U, EG EAC with gly, U, EG, ZnCl2 and MA |
Aspergillus niger Cyprinus carpio fish |
MIC values EAC:ZnCl2<EAC:MA < ChCl:U <ChCl: EG < EACgly < ChCl:gly Dose-dependent results on Agar diffusion Same trend for fish toxicity |
[68] |
8 | ChCl with gly, EG, DEG, TEG, Frc, Glc, MA, PTSA, ZnCl2 and U |
Phanerochaete chrysosporium, Aspergillus niger, Lentinus tigrinus, Candida cylindracea Cyprinus carpio fish |
ChCl with U, gly, Frc, and Glc showed no inhibition to all fungi Highest values of inhibition were found for C. cylindracea Only ChCl:ZnCl2 was toxic for fish |
