Bacillus licheniformis and applications thereof

The invention relates to Bacillus licheniformis P-104 for gamma-PGA (gamma-polyglutamic acid) fermentation production and applications thereof. The Bacillus licheniformis P-104 is conserved in China General Microbiological Culture Collection Center (CGMCC) on September 14, 2010 with the conservation number of CGMCC NO.4156. The Bacillus licheniformis P-104 is obtained by screening and separating the Chinese traditional fermented bean paste product, and has the advantages of short production period, high production efficiency and low production cost. By using the strain and fermentation method thereof provided by the invention, the output of a 7 L fermentation tank of gamma-PGA can reach 32 g/L, and the fed-batch fermentation yield reaches 41.6 g/L.
