Evaluation of electron-shuttling compounds in microbial ferric iron reduction.

Iron-reducing bacteria can transfer electrons to ferric iron oxides which are barely soluble at neutral pH, and electron-shuttling compounds or chelators are discussed to be involved in this process. Experiments using semipermeable membranes for separation of ferric iron-reducing bacteria from ferric iron oxides do not provide conclusive results in this respect. Here, we used ferrihydrite embed...

Microbial Reduction of Hexavalent Chromium

Publication 1. A. Manceau et al, “Quantitative Zn speciation in smelter-contaminated soils by EXAFS spectroscopy,” Am. J. Sci. (in press, 2000). Figure 3 (top) Soil samples were taken at several depths from a contaminated site. (bottom) Model compounds derived from polarized-EXAFS data at the ESRF and μ-EXAFS data at the ALS provide a good fit with powder-EXAFS spectra from a soil sample, there...

Isolation of chromium resistant Bacillus sp. MRKV and reduction of hexavalent chromium potassium dichromate

The ability of Bacillus sp. MRKV isolated from tannery effluent which shows resistant towards hexavalent chromium potassium dichromate (K2Cr2O7) was evaluated in this study. The bacterial strain was assayed for its reducing ability towards K2Cr2O7. The study revealed that the isolated strain has the ability to reduce the hexavalent chromium and the optimal conditions required for the chromium r...

Iron stimulates the rate of reduction of hexavalent chromium by human microsomes.

The NADPH-dependent reduction of chromium (VI), a known carcinogen, by hepatic microsomes was very similar for all five humans examined, with an apparent Km for chromate of 1.04-1.68 microM, and a Vmax of 10.4-10.7 nmol/min/mg protein. Inhibitor studies indicate no role for cytochrome P450s, but a prominent role for flavoproteins, which could include P450 reductase, flavin-containing mono-oxyge...
