Oxygen is a limiting factor in the production of γ-PGA by the glutamic acid-independent strain Bacillus amyloliquefaciens LL3 because of the high viscosity of the culture broth.The vgb gene encoding V
Bacillus amyloliquefaciens LL3 is a glutamate-independent poly (γ-glutamic acid) (γ-PGA) producing strain which consists of a circular chromosome (3,995,227 bp) and an endogenous plasmid pMC1 (6,758 b
