Fig. 5From: Efficient 2,3-butanediol production from whey powder using metabolically engineered Klebsiella oxytocaFed-batch fermentation using lactose (a) and whey powder (b) as the carbon source. Biomass, consumption of lactose, concentration of BDO and acetoin (AC) by K. oxytoca PDL-K5 were assayed. The experiments were conducted in a 7.5-L fermenter containing 5 L of medium with an initial lactose concentration of 100 g/L approximatelyBack to article page
