Abstract: Bacterial Strains were isolated and enriched from contaminated sites of Mohkampur and Partapur industrial area in Meerut, Uttar Pradesh at regular intervals for a period of 30 months between 2018 and 2021. The strains isolated showed high efficiency towards reduction of Chromium VI variety in aerobic as well as anaerobic conditions. During the course of experimentations several varying levels of BOD and COD of isolated were observed. It was also found that strains performed better in aerobic conditions in comparison to anaerobic environment. It is safely concluded that isolated strains proved to be a successful remedy in bioremediation of toxic Chromium VI from contaminated soils.
