Poly-L-gamma-glutamic acid production by recombinant Bacillus subtilis without pgsA gene.

abstract：:In this paper, we demonstrate that the antimicrobial activity of L. plantarum PBS067 strain against antagonist microorganisms was mediated by the production of a bacteriocin-like compound secreted at the stationary phase of the growth. The novel bacteriocin-like compound, designed plantaricin P1053, was identified by ...
