A comprehensive review on chromium (Cr) contamination and Cr (VI)-resistant extremophiles in diverse extreme environments
Chromium (Cr) compounds are usually toxins and exist abundantly in two different forms, Cr
(VI) and Cr (III), in nature. Their contamination in any environment is a major problem. Many …
