Abstract
Microbe-induced remediation of toxic metals has attained more research interests by implementing the bioremediation process for sustainable development. Heavy metals are known to be naturally occurring elements, but they are released in vast quantities into different environmental sources due to anthropogenic activity. Metals are persisting and non-biodegradable, which can enter the food chain via crop plants, and might accumulate in the animal body through biomagnification. At the molecular level, microbial treatment of metals provides an excellent and new perspective for the prevention of environmental pollution. Novel bioremediation organisms provide excellent and new perspectives through their specific biodegradation mechanisms at the molecular level. All DNA found within the metagenomic analysis of a populated environment includes several screening approaches that might be used to simplify the processing and examination of specific genomic information in bioremediation experiments. Development in next-generation sequencing (NGS) demands detailed metagenomic analysis of environmental microbes offering unparalleled perspectives through key biosorption mechanisms. The present review explored how the metagenomic approaches could help in analyzing the functional and structural characteristics of microbial communities in response to metal detoxification.
