Influence of biodegrading polymers on las regulon activity in P. aeruginosa pMHLAS mutant: (A) Transmitted light micrograph of P. aeruginosa pMHLAS during the attachment phase of biofilm development on the inactive, control polymer; and (B) the same image under UV illumination indicating activation of the las regulon. (C) Transmitted light micrograph of P. aeruginosa pMHLAS during the attachment phase of biofilm development on active polymer, salicylate-based polymer that slowly releases salicylic acid upon biodegradation; and (D) the same image under UV illumination indicating inactivation of the las regulon.
