EPS analysis. (A) Effects of proteinase K on pellicle formation and developed pellicles. Upper-panel, pellicle formation of the WT in static LB, in which the proteinase K was added at inoculation to 100 mg/ml (final concentration). Lower panel, developed pellicles of the WT (48 h after inoculation) were treated with 100 mg/ml (final concentration). (B) TLC analysis of monosaccharide in pellicles and supernatants. P and S represent pellicle and supernatant, respectively. Man, gal, and glu represent mannose, galactose, and glucose, respectively. Supernatants of the aggA mutant culture were included in the analysis.
