A critical review on bioremediation technologies for Cr(VI)-contaminated soils and wastewater

Critical reviews in environmental science and technology, 2019
Chromium (Cr) is a potentially toxic metal originating from natural processes and anthropogenic activities such as the iron-steel, electroplating, and leather industries, which is carcinogen to living organisms and has an ecological risk. Hence, research
