FIG. 2.

Growth of X. campestris pv. campestris wild-type and mutant strains in the presence of N-acetylglucosamine (GlcNAc) or other carbon sources. (A) Growth of the wild-type strain in the presence of carbon sources and in the presence of carbon and nitrogen sources. (B) Growth of the wild-type strain in the presence of GlcNAc, chitobiose, or chitin. (C) Growth of the wild type (WT) and mutant strains in the presence (+) or in the absence (−) of GlcNAc. After overnight growth in complete medium, cells were harvested, washed, and resuspended in minimal medium. Carbohydrates were added at a final concentration of 10 mM (A and C) or 0.1% (B). The error bars indicate the standard deviations obtained from 4 independent experiments.
