Cell debris were removed by centrifugation (20 min, 4uC, 14,000 g), and the resulting crude cell extract was filtered by way of polyethersulfone column (ten kDa Vivaspin500). In NAHL-degradation assay, the reaction mixture contained cell absolutely free extract at a final concentration of ten mg/mL and C6HSL at 50 mM within a finalvolume of 1 ml of KPBS buffer. Assays had been incubated at 30uC up to 24 h, and filtered by way of polyethersulfone column (10 kDa Vivaspin500). Thirty to 50 mL had been analyzed by HPLC (Waters Alliance 2690) conjugated with LC-MS/MS (Waters ZQ Mass Spectrometer with single quadrupole program and electrospray ionization). To detect C6HSL, a Gemini C18 5 mmPLOS 1 | plosone.orgQuorum-Quenching in the Amidase Signature Familyexpression was induced with 0,5 mM IPTG throughout five h. The cells have been harvested and stored at 220uC. The pellet was suspended in buffer A (50 mMTris l buffer, pH 8, 20 mM imidazole, 10 glycerol and 500 mM NaCl) and disrupted by sonication. The lysate was cleared by centrifugation at 20,000 g for 30 min at 4uC. The supernatant was filtered by way of a 0.22 mm membrane (Millipore.
