Morphotypes observation and quantitative analysis of EPS production. a The morphology of colonies (WT, ΔacfR, and ΔacfR-C) grown on L3 Congo red plates at 37 °C for 2–3 days. L3 plates contain 10 mM glycine or sodium lactate as the sole carbon source. b Quantitative analysis of the total EPS produced by strains of WT, ΔacfR, and ΔacfR-C. The error bars indicate standard deviations which were calculated by three independent experiments. Statistically significant differences between the WT and mutant strain was indicated by the asterisks (**P ≤ 0.01)
