Comparative Analysis on Metal Removal Potential of Exopolymeric Substances with Live and Dead Cells of Bacteria

The Efficacy of 5-Aminolevulinic Acid-Producing Luteovulum sphaeroides Strains on Saline Soil Fertility, Nutrient Uptakes, and Yield of Rice

“…Furthermore, the PNSB secrete more EPS under saline conditions [31]. Previous studies also found that functional groups, including -OH, -COOH, and amines as the components of EPS, can immobilize Na + [16,[32][33][34]. In addition, this was in accordance with the study by Nunkaew et al [35], where the strains of PNSB R. palustris TN114 and PP803 reduced Na + by producing EPS, whose main component is a polysaccharide containing galacturonic acid.…”

Bioleaching of As from mine tailings using an autochthonous Bacillus cereus strain

“…This same issue was also discussed by Mohd-Bahari et al (2013) where dead biomass of B. cereus was used and additionally demonstrated that once the biomass was used as a sorbent, it can be reused again achieving up to 94% desorption at a pH of 1, which indicates a high potential of this bacterium to be used in various applications during the leaching process. In recent studies, Cheah et al (2022) compared the efficiency of exopolymeric substances (EPS), using live and dead cells of B. cereus to remove heavy metals. It was shown that there was a higher removal efficiency with dead cells reaching removals for Cu (63.26%), Pb (70.16%), Zn (58.86%), Cd (57.68%), and Cr (56.48%).…”
