Metagenomics in studying salt tolerance enzymes and salt tolerance genes

Abstract:

Salt tolerance enzymes are active and stable at high salt concentrations and widely applied in high salt food processing, seafood processing, washing and other biotechnology fields with high salt concentrations. Salt tolerance genes can maintain normal function of microorganisms under high salt conditions. Therefore, obtaining and exploration of salt tolerance genes and salt tolerance enzymes in different environments have profound significance for revealing the salt tolerance mechanism of microorganisms and directing its application in the high salinity environment. The metagenomic technology skips the pure culture to explore the diversity and function of microorganisms and provide a new technology for discovering novel genes, developing new microbial active substances and studying microbial community structure and function. Combined with our own findings, this paper summarizes the strategies of using metagenomic technology to acquire salt tolerance enzymes and salt tolerance genes, and emphatically introduces the study of obtaining salt tolerance enzymes and salt tolerance genes from ocean, soil and gastrointestinal tract environment with metagenomics.
