Bacterial Cr(VI) Reduction with Internal Carbon Recirculation Using Freshwater Algae as Primary Producers [PDF]

Chemical Engineering Transactions, 2018
Chromium exits naturally in two oxidation states: hexavalent chromium (Cr(VI)) and trivalent chromium (Cr(III)). Cr(VI) is carcinogenic and mutagenic to living organisms and Cr(III) is 100 times less toxic than Cr(VI).
