WebApr 13, 2024 · Cr exists in one of two stable oxidation states in the environment, Cr 6+ and Cr 3+, and Cr 3+ is a less hazardous form of Cr 6+ (Mitra et al., 2024). Microorganisms can enzymatically reduce Cr 6+ to Cr 3+ for tolerance. Under aerobic conditions, the reduction is mediated by soluble and membrane-bound reductases such as ChrR and YieF. bmal 590 quantitative research answers
