Abstract:As an important component of the biological community, the growth of microorganisms is greatly affected by external physicochemical conditions (such as temperature, salinity, pH, etc.). Hot springs, as one of the extreme aquatic environments, belong to a relatively stable and special ecosystem. Microorganisms growing in hot springs may have special survival physiological mechanisms that are adapted to special environments such as high temperatures. More specifically, diversity and novelty are high in microbial species and their active secondary metabolites. This paper reviews the research progress of microorganisms in Chinese hot springs from January 2015 to August 2020 with a focus on microbial species diversity and enzymatic activity, in order to provide references for the exploitation and protection of microbial resources in hot spring and other extreme environments.
