FIG. 5.

Extracellular polysaccharide quantification and growth inhibition test. (A) Relative amount of extracellular polysaccharide in bacteria grown on MMMF plate for 48 h at 27°C. (B) Photographs of growth inhibition on plates by 50 μg/μl ampicillin (Amp) and 35 μg/μl chloramphenicol (Cm). (C) Growth inhibition of each bacterial strain by 7.5% and 15% H₂O₂, 50 μg/μl and 25 μg/μl ampicillin, and 35 μg/μl and 17.5 μg/μl chloramphenicol. C, orf3-complemented strain. Error bars indicate standard deviations.
