Effect of nitrogen source type on one-step fermentation. a Effect of nitrogen source type on XOS production, xylanase activity and biomass of recombinant E. coli. “Activity”: xylanase activity measured using supernatant of medium; “Activity after dialysis”: xylanase activity measured using dialysis-treated supernatant of medium. b Correlation between XOS concentration and xylanase activity as well as wheat bran concentration. Wheat bran concentration: 2%. Fermentation time: 12 h. Temperature: 37 °C. Initial pH: 7.0. In (a), data are presented as means ± standard deviations (n = 3)
