WebJan 18, 2009 · Quorum sensing is believed to control swarming through rhamnolipid production, as the rhlAB genes are QS-regulated (Ochsner et al., 1994a). Evidence has been presented supporting a role for bacterial migration in both early and late stages of biofilm development that is dependent upon pili, flagella and rhamnolipid. WebDec 1, 2024 · Biofilm formation is a complex process influenced by many factors. Quorum sensing (QS) is a cell-to-cell communication process that allows microorganisms to behave coordinately in response to environmental changes by producing, secreting, and detecting signal molecules ( Bassler, 1999; Subramani and Jayaprakashvel, 2024 ).
