Effects of DO levels on DCW and production of L-tryptophan during L-tryptophan fermentation. The DCW and growth rate of the strain obtained at DO levels of 20 and 30 % show no statistical difference, while 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 levels, respectively
