Quantification of antibiotic production. Production of prodiginines (top) and actinorhodin (bottom) was quantified relative to their production by the parental strain S. coelicolor M145 (which was set to 100%). Cultures were grown for 42 h (Red) or 48 h (Act) on R2YE agar plates with (dark bars) or without (light bars) GlcNAc. For data obtained at 120 h, see Fig. S2 in the supplemental material.
