Figure 6From: Efficient bioconversion of 2,3-butanediol into acetoin using Gluconobacter oxydans DSM 2003Time course of batch bioconversion of acetoin from 2,3-butanediol. The bioconversion was carried out at 30°C in 300 mL shake flasks containing 50 mL of medium at pH 6.0. The initial 2,3-butanediol concentration used was 40 g/L. Biomass (black circle); 2,3-butanediol (blue square); and acetoin (red triangle).Back to article page
