Z.mobilis (ATCC 29191) produced ethanol in significantly greater yield thanS. cerevisiae, (0.49 vs 0.45 g ethanol/g glucose entering the system), in multistage continuous culture, on commercial feedstocks obtained from corn wet milling operations. In the same system, Z.mobilis showed higher volumetric productivity (4.14 vs 3.06 g/L/h) than S.cerevisiae. The approximately 9% increase improvement in ethanol production that should result from the improvement in yield makes the cost for retrofitting a plant for the Z.mobilis process minimal.
