Chromium mainly exists in ,wastewater, by ,Cr, (III) and ,Cr, (VI). ,Cr, (VI) is easy to accumulate in organisms and water because of its solubility, strong oxidation, toxicity and other characteristics [4]. Chromium- ,containing wastewater treatment, is particularly important and must be treated before discharged.

Biological treatment of chromium-containing wastewater has great potential due to its economy, efficiency and safety (Pradhan et al. 2017). In the late 1970s, Romanenko & Koren'Kov (1977) isolated a genus (Pseudomonas) that can reduce Cr(VI) under anaerobic conditions. This was the first report of microbial reduction of Cr(VI).
