Fig. 4From: Efficient 2,3-butanediol production from whey powder using metabolically engineered Klebsiella oxytocaBatch fermentation using lactose as carbon source. Biomass, consumption of lactose, concentration of BDO and acetoin (AC) by K. oxytoca PDL-0 (a) and K. oxytoca PDL-K5 (b) were assayed. The experiments were conducted in a 1-L fermenter containing 800 mL of medium with an initial lactose concentration of 40 g/L approximatelyBack to article page
