The characteristics of mutant strain PmCQ2Δ4555–4580. A: Colony morphology of PmCQ2, and PmCQ2Δ4555–4580. B: Bacterial growth curves of PmCQ2, and PmCQ2Δ4555–4580 based on OD600. C: The precipitation condition of PmCQ2, and PmCQ2Δ4555–4580 at 10,000 rpm for 5 min. D: The content of capsule polysaccharide in PmCQ2, and PmCQ2Δ4555–4580. The data of B and D were pooled from three independent experiments with 6 replicates per group, and B was analyzed by multiple comparative analysis, and expressed as means ± SD. *P < 0.05, **P < 0.01, ***P < 0.001
