Effects of reaction condition on GABA production. Conversion reactions were performed at different a temperature and b cell concentrations with shaking at 200 rpm for 3 h. Data are presented as the mean ± SD values from three independent experiments. The bars represent GABA concentrations and the square symbols represent a volumetric productivity, b cell productivity
