Fig. 4From: Quantitative proteomic analysis to reveal expression differences for butanol production from glycerol and glucose by Clostridium sp. strain CT7 The protein-protein interaction network of changed proteins fed with glycerol and glucose in Clostridium sp. strain CT7 at the early (a) and late (b) fermentation stages. The red circles represented the up-regulated proteins and the green circles were those down-regulated onesBack to article page
