Chromium reduction in Pseudomonas putida

Journal Article · · Applied and Environmental Microbiology; (USA)
OSTI ID:5857429
Reduction of hexavalent chromium (chromate) to less-toxic trivalent chromium was studied by using cell suspensions and cell-free supernatant fluids from Pseudomonas putida PRS2000. Chromate reductase activity was associated with soluble protein and not with the membrane fraction. The crude enzyme activity was heat labile and showed a K{sub m} of 40 {mu}M CrO{sub 4}{sup 2{minus}}. Neither sulfate nor nitrate affected chromate reduction either in vitro or with intact cells.
