The selective breeding and mutagenesis mechanism of high‐yielding surfactin Bacillus subtilis strains with atmospheric and room temperature plasma

ARTP mutagenesis was found to change the morphology of bacteria, membrane permeability and genes related to the synthesis and secretion of surfactin. The present study provides a basis for industrial production of surfactin and an understanding of the mutagenesis mechanism. © 2021 Society of Chemical Industry.
