Aerobic Cr(VI) Reduction by Bacteria in Culture and Soil Conditions
, 2013 We compared the performance of aerobic Cr(VI)-reducing bacteria isolated from Cr(VI)-contaminated soil in pure and mixed cultures of five isolated strains. The mixed culture had increased reduction rates compared to individual cultures.

Direct Cr (VI) bio-reduction with organics as electron donor by anaerobic sludge [PDF]
, 2017 Industrial activities produce lots of Cr (VI)-containing wastewater. This study presented a detailed work on direct Cr (VI) bio-reduction (i.e. Cr (VI) is reduced with organics as electron donor directly) by anaerobic sludge through both batch and long ...

Hexavalent chromium reduction under fermentative conditions with lactate stimulated native microbial communities. [PDF]
PLoS ONE, 2013 Microbial reduction of toxic hexavalent chromium (Cr(VI)) in-situ is a plausible bioremediation strategy in electron-acceptor limited environments. However, higher [Cr(VI)] may impose stress on syntrophic communities and impact community structure and ...

In Situ Biostimulation of Cr(VI) Reduction in a Fast-Flowing Oxic Aquifer [PDF]
, 2020 Hexavalent chromium is among the most common and hazardous inorganic contaminants in soils and groundwater. A promising in situ bioremediation approach is the delivery of electron donors to stimulate microbially mediated Cr(VI) reduction, producing ...

Influence of soil minerals on chromium(VI) reduction by sulfide under anoxic conditions
Geochemical Transactions, 2007 The effects of soil minerals on chromate (CrVIO42-, noted as Cr(VI)) reduction by sulfide were investigated in the pH range of 7.67 to 9.07 under the anoxic condition. The examined minerals included montmorillonite (Swy-2), illite (IMt-2), kaolinite (KGa-

CHROMIUM(VI) REDUCTION BY A MIXED CULTURE OF SULFATE REDUCING BACTERIA DEVELOPED IN COLUMN REACTOR
Jurnal Manusia dan Lingkungan, 2008 A lactate enriched mixed sulfate reducing bacteria (SRB) culture was examined for the reduction of Cr(VI) in a continuous flow system. The influent was mineral salts media added with lactate and sulfate with amounts of 8 and 6 mM respectively as electron
