Increased expression of <i>PA0506</i> alters PQS production.

Abstract

<p>The indicated strains were grown for 24 h in LB medium harboring pHERD20T (control plasmid) or pGW-21 (<i>PA0506</i> expression plasmid) indicated by a minus or plus symbol, respectively. Cultures were supplemented with 0.5% L-arabinose to induce <i>PA0506</i> expression, and PQS was then extracted and quantified. Data are presented as the average ± SD of three independent experiments.</p
