Time profiles of GABA produced in a MSG buffer and b l-Glu solution by E. coli BW25113 expressing different GadB. Conversions were performed at 37 °C and 25 g wet cell per liter. Data are presented as the mean ± SD values from three independent experiments. Square, down triangle, diamond and circle symbolize the E. coli BW25113 and recombinant E. coli BW25113 harboring pYB-pgadB, pYB-bgadB and pYB-lgadB, respectively
