a
Carbon sources were added in the medium at the concentration of 0.5% (wt/vol).
b
Doubling times are expressed in minutes. Results are the mean of three independent repeats. NAG, N-acetylglucosamine; *, values were significantly different from the WT (P < 0.05); **, values were significantly different from the WT (P < 0.1).
