Hexavalent chromium reduction and bioremediation potential of Fusarium proliferatum S4 isolated from chromium-contaminated soil.

Microbial remediation, utilizing reduction of Cr(VI) to Cr(III), is considered a promising method for lowering toxic environmental chromium levels. In this study, a Cr(VI)-resistant fungal strain, Fusarium proliferatum S4 (F. proliferatum), was isolated from seriously chromium-polluted soil at Haibei Chemical Plant, China.

Proteomics study on immobilization of Pb(II) by Penicillium polonicum.

Lead (Pb) is widely distributed in nature and has important industrial applications, while being highly toxic. In this study, the Pb(II) biosorption and immobilization behavior of Penicillium polonicum was investigated through surface morphology observation and multiple experimental analysis. In addition, the molecular mechanism of Pb(II) immobilization was further explored through proteomics.

Efficient immobilization behavior and mechanism investigation of Pb(II) by Aspergillus tubingensis.

Objectives: To understand the mechanism of Pb(II) immobilized by Pb(II)-tolerant microbes.

Results: Aspergillus tubingensis isolated from the lead-zine mine was investigated through surface morphology observation and multiple experimental analysis in order to elucidate the Pb(II) biosorption and immobilization behavior. The maximum Pb(II) uptake capacity of A.

A review on mechanism of biomineralization using microbial-induced precipitation for immobilizing lead ions.

Lead (Pb) is a toxic metal originating from natural processes and anthropogenic activities such as coal power plants, mining, waste gas fuel, leather whipping, paint, and battery factories, which has adverse effects on the ecosystem and the health of human beings. Hence, the studies about investigating the remediation of Pb pollution have aroused extensive attention. Microbial remediation has the advantages of lower cost, higher efficiency, and less impact on the environment.
