摘要
The arsenic biogeochemical cycle is vastly influenced by the biotransformation of arsenic. The insights within the complexities of this bio-cycle can be determined using microbial community analysis by meta-omics coupled with the identification of microbial pathways influencing the biotransformation of arsenic. The fate of toxic environmental contaminants and nutrients is governed by the microbial arsenic transformations in the biogeochemical cycle. The bioavailability of arsenic species is greatly prejudiced by the microbial redox metabolism of carbon, iron, nitrogen, and sulphur. In this chapter, we exemplify the genes and microbial biogeochemical processes concerned with the biotransformation of arsenic. The importance of deciphering the individual microbial communities using the current and future omic approaches will aid in determining their connections to other cycles of biogeochemical nature. Specific biotechnological solutions could be designed for environmental problems using these microbial metabolic insights. A thorough biochemical modelling integrated with systematic approaches is needed to comprehend the complex nature of organic, inorganic, and environmental arsenic species. Hence, a relation between arsenic biotransformation and the environment could be adjudged which will pave the way for further studies on arsenic biogeochemistry.
