Toward Industrial Application of Cyanobacterial Biosorption: Insights From Real Electroplating Effluents. [PDF]

Water Environ Res
The study demonstrates that exopolysaccharide‐producing cyanobacteria are effective biosorbents for metals contained in electroplating wastewater. Ni uptake (2.3–2.9 mmol/g) was higher than for precious metals such as palladium (Pd) and gold (Au) (lower than 0.1 mmol/g). D. salina 16Som2 and Cyanothece sp. CE 4 showed the best performances.

Valorization of keratin biofibers for removing heavy metals from aqueous solutions [PDF]

, 2018
Four common waste keratin biofibers (human hair, dog hair, chicken feathers, and degreased wool) have been used as biosorbents for the removal of heavy metal ions from aqueous solutions. Different parameters of the biosorption processes were optimized in

Reduction of Hexavalent Chromium by Stenotrophomonas and Bacillus [PDF]

Microbiologyopen
Stenotrophomonas and Bacillus remove toxic hexavalent chromium via enzymatic reduction and non‐enzymatic mechanisms. Reductases (e.g., ChrR, HhuH, YhdA, NfrA, Bcr005, NitR, AzoR) use NAD(P)H to convert Cr(VI) to the less toxic Cr(III). ABSTRACT Hexavalent chromium [Cr(VI)] is a widespread environmental pollutant, posing a significant health risk to ...

Effect of chemical extractants on the biosorptive properties of pine cone powder: Influence on lead(II) removal mechanism

Journal of Saudi Chemical Society, 2011
This study examines the changes in surface properties and lead(II) adsorption mechanism of pine cone powder modified using varying ratios of toluene–ethanol mixtures. Increasing the ratio of toluene in the extractant mixture increased formation of esters
