WebNov 16, 2016 · Pseudomonas aeruginosa employs several overlapping QS circuits including the pqs system to control the expression of virulence determinants. The pqs QS system relies on multiple 2-alkyl-4-quinolones (AQs), including the Pseudomonas Quinolone Signal (PQS), as signal molecules. WebSep 1, 2008 · Preliminary studies were performed in shake flasks to characterize RhuA overexpression after IPTG induction. Six parallel cultures were grown at 5 g L −1 of initial glucose concentration and, during the exponential growth phase, an early pulse of IPTG (at 0.13 g DCW L −1 approximately) was added into five of them so that all cultures could …
