Fig. 3From: Investigation of two metabolic engineering approaches for (R,R)-2,3-butanediol production from glycerol in Bacillus subtilisMetabolic fluxes illustrating the enhancing effect of zwf gene knockout on the production of lactate. Blue arrows indicate unchanged metabolic fluxes. Red arrows indicate flux decrease relative to wild-type level. Green arrows indicate flux increase relative to wild-type levelBack to article page
