Fig 5. The disruption of rpoS has diverse effects on the physiology and motility of 1912768R.

(A) Diverse physiology of biofilm formation, lipase and proteinase secretion, hemolysis ability, production of siderophores and chitinase activeity. (B) Mobility and TEM analysis of the WT strain and the rpoS mutant. (C) Changes in the transcript levels of motility-related genes. qRT-PCR of fliC and flhCD gene expression, n = 4. Mean and SD are shown. *, P < 0.05; **, P< 0.01.
