Abstract

Anthropogenic sources of toxic cadmium (Cd) have significantly risen during the past few decades. Currently several physical and chemical techniques are used in the Cd decontamination methods. But these techniques are expensive and even causes secondary pollution. Therefore, it is crucial to investigate eco-friendly, effective, and affordable strategies that can eliminate the Cd threat from the environment. The biological methods are far suitable than other methods in recent years. A bunch of bacteria (Bacillus cereus, Aeromonas caviae) are able to tolerate this heavy metal. Cadmium tolarent bacteria (CdtB) are numerous and unrelated phylogenetically. They contain cadA and cadB gene systems which is responsible for their Cd-resistant capacity. The objective of this review is to demonstrate the importance, culturable diversity, metabolic purification mechanisms, and contemporary applications of CdtB bacteria in soil bioremediation processes.
