From: One-step fermentation for producing xylo-oligosaccharides from wheat bran by recombinant Escherichia coli containing an alkaline xylanase

Fig. 3

The time course of a XOS concentration and b extracellular xylanase activity during one-step fermentation. “With IPTG”: employ of inducer (IPTG), wheat bran and recombinant E. coli containing rBaxyl11; “Without IPTG”: employ of wheat bran and recombinant E. coli containing rBaxyl11 without inducer; “Empty vector”: employ of inducer, wheat bran and recombinant E. coli containing unmodified pET22b(+); “Without wheat bran”: employ of inducer and recombinant E. coli containing rBaxyl11 without wheat bran. Wheat bran concentration: 2%. All data are presented as means ± standard deviations (n = 3)
