Fig. 5From: One-step fermentation for producing xylo-oligosaccharides from wheat bran by recombinant Escherichia coli containing an alkaline xylanaseEffect of wheat bran concentration on one-step fermentation. a Effect of wheat bran concentration on XOS production, xylanase activity and biomass of recombinant E. coli. b Correlation between XOS concentration and xylanase activity as well as wheat bran concentration. Fermentation time: 12 h. Temperature: 37 °C. Initial pH: 7.0. In (a), data are presented as means ± standard deviations (n = 3)Back to article page
