Abstract
Bacillus subtilis is a model strain for studying the physiological and biochemical mechanisms of microorganism, and is also a good chassis cell for industrial application to produce biological agents such as small molecule compounds, bulk chemicals, industrial enzymes, precursors of drugs and health product. In recent years, studies on metabolic engineering methods and strategies of B. subtilis have been increasingly reported, providing good tools and theoretical references for using it as chassis cells to produce biological agents. This review provides information on systematically optimizing the Bacillus subtilis chassis cell by regulating global regulatory factors, simplifying and optimizing the genome, multi-site and multi-dimensional regulating, dynamic regulating through biosensors, membrane protein engineering. For producing the protein reagent, the strain is optimized by optimizing the promoters, signal peptides, secretion components and building the expression system without chemical inducers. In addition, this review also prospects the important issues and directions that need to be focused on in the further optimization of B. subtilis in industrial production.
