Fig. 1From: Rewiring glycerol metabolism for enhanced production of poly-γ-glutamic acid in Bacillus licheniformisA schematic diagram of γ-PGA synthesis from glycerol in B. licheniformis and genetic modification strategies for producing γ-PGA employed in this study. Relevant reactions are represented by the genes. Dotted lines illustrate multiple steps, and bold lines denote over-expression of genesBack to article page
