Abstract: Microorganisms are  important resources for human survival. In order to improve the production efficiency of microorganisms or endow them with new biological functions, mutagenesis by physical and chemical methods or site-directed mutagenesis by molecular biological techniques are required. Among the current methods of physical and chemical mutagenesis, atmospheric and room temperature plasma (ARTP) has become a favored new method due to its advantages of simple operation, mild conditions, high safety and rapid mutagenesis. Based on this, the principle of ARTP mutagenesis technology and its application in microbial mutation breeding were summarized, in order to provide reference for the mutation breeding related research of breeding superior microbial strains.

Key words: microorganism, atmospheric and room temperature plasma, mutagenesis
