Fig. 2From: Rewiring glycerol metabolism for enhanced production of poly-γ-glutamic acid in Bacillus licheniformisThe γ-PGA production, biomass, and glycerol consumption by mutant strains using glycerol as a carbon source at 48 h. a Mutant strains involved in glycerol catabolism pathway; b mutant strains involved in gluconeogenesis pathway; c mutant strains involved in pentose phosphate pathway. Data are represented as the means of three replicates and bars represent the standard deviations. *P < 0.05 and **P < 0.01 indicate the significance levels between original WX-02 and its mutant strainsBack to article page
