Effects of DO stage control strategy on DCW and production of L-tryptophan in L-tryptophan fermentation. The difference in DCW and growth rate of the strain between DO stage control strategies I and II and between stage control strategies III and IV are not statistically significant, whereas the other data show a statistical difference (p < 0.05). a, b, c and d DCW, growth rate of strain, production of L-tryptophan, and production rate of L-tryptophan with different DO stage control strategies, respectively
