Bacillus megaterium and application thereof

The invention belongs to the technical field of biological fermentation engineering, and particularly relates to a patent application of bacillus megaterium and an application of the bacillus megaterium. A bacillus megaterium YSJ3 strain is preserved in the China General Microbiological Culture Collection Center, namely Institute of Microbiology Chinese Academy of Sciences at NO.1 West Beichen Road, Chaoyang District, Beijing on December 5th, 2019 with a preservation number of CGMCC 19088. In the application, an inventor finally obtains the bacillus megaterium YSJ3 strain which has good growthvigour through combined application of ultraviolet mutagenesis and plasma beam mutagenesis technologies as well as directed screening and breeding on the basis of an existing bacillus megaterium YSJ1strain. A preliminary experiment result indicates that the highest fermentation activity of the YSJ3 strain can be 15 billion/ mL or above, the YSJ3 strain shows a good growth effect, and a good technical foundation can be la
