Fig. 4From: Modular pathway engineering of key precursor supply pathways for lacto-N-neotetraose production in Bacillus subtilisEffects of UDP-GlcNAc and UDP-Gal supply module on LNnT biosynthesis. a Four strengthen levels of UDP-GlcNAc module. b Four strengthen levels of UDP-Gal module. c Influences of modular engineering of LNnT and LNTII. Triplicate experiments were done, and error bars represent the standard deviation. * and** mean p < 0.05 and p < 0.01, respectivelyBack to article page
