Fig. 3From: Modular pathway engineering of key precursor supply pathways for lacto-N-neotetraose production in Bacillus subtilisIdentifying positive-acting enzymes in the UDP-GlcNAc and UDP-Gal pathways. a Schematic of the cassette used to overexpress gene in B. subtilis. b Schematic of the cassette used to knockout gene in B. subtilis. c LNTII, LNnT titer of BY08 ~ BY12 and the control host BY06. d LNTII, LNnT titer of BY13–BY17 and the control host BY04. Triplicate experiments were done, and error bars represent the standard deviation. * and** mean p < 0.05 and p < 0.01, respectivelyBack to article page
