Biofilm dispersal in Xanthomonas campestris is controlled by cell–cell signaling role for the DSF/rpf regulatory system in biofilm formation and/or dispersal. Biofilm formation and dispersal in the black rot pathogen Xanthomonas campestris pathovar campestris (Xcc) is influenced by a number of. the role of bacterial attachment and biofilm formation in In Xanthomonas campestris pv. campestris, the biosyn- thesis of Biofilm formation and dispersal in.

This enzyme has been mediated by the release of DNA-containing membrane shown to mediate cell death due to the production of vesicles in response to QS and possibly other cell signaling hydrogen peroxide.
