Figure 7From: Improving the stability of glutamate fermentation by Corynebacterium glutamicum via supplementing sorbitol or glycerol Glutamate fermentation performance when less amount of sorbitol or glycerol was added in the initial medium. White square and dotted line, abnormal batch without sorbitol or glycerol; black square and dashed line, 5 g/L sorbitol added in the initial medium; black circle and solid line, 4 g/L glycerol added in the initial medium; arrow, glucose fed. a: Time courses of cell concentration (OD620) in different operation conditions; b: Time courses of glutamate concentration in different operation conditions; c: Time courses of RQ in different operation conditions; d: Time courses of ORP in different operation conditions.Back to article page
