“…This implies that it would not be possible to continuously remove Cr(VI) on a long-term basis without intermittently reseeding the biological system. However, there are recent reports concerning stable biological Cr(VI) reduction in continuous systems which could contradict this theory [21,31,32].…”

“…A variety of micro-organisms, including bacteria and fungus, have been identified to be able to reduce Cr(VI), hence this reduction is agreed to be enzymatic. Most batch studies have been aimed at optimizing physical conditions, establishing the biochemical mechanisms involved and analyzing kinetic potential (Caravelli and Zaritzky, 2009). …”

“…However, these methods possess several disadvantages like high cost and produce large quantity of secondary waste. The advantages of using bioremediation of toxic heavy metals and organic compounds in comparison to above processes are natural process, cost effective, green environment technology, toxic metal is completely destroyed or consumed by bacterium not just separated, and less energy is required in comparison to other methods [18,19]. Phenol was utilized as electron donor by the microorganism for reduction of Cr(VI) [20].…”
