      <dc:description>The Alteromonas stellipolaris strains PQQ-42 and PQQ-44, previously isolated from a fish hatchery,&#xd;
have been selected on the basis of their strong quorum quenching (QQ) activity, as well as their ability&#xd;
to reduce Vibrio-induced mortality on the coral Oculina patagonica. In this study, the genome sequences&#xd;
of both strains were determined and analyzed in order to identify the mechanism responsible for QQ&#xd;
activity. Both PQQ-42 and PQQ-44 were found to degrade a wide range of N-acylhomoserine lactone&#xd;
(AHL) QS signals, possibly due to the presence of an aac gene which encodes an AHL amidohydrolase. In&#xd;
addition, the different colony morphologies exhibited by the strains could be related to the differences&#xd;
observed in genes encoding cell wall biosynthesis and exopolysaccharide (EPS) production. The PQQ-42&#xd;
strain produces more EPS (0.36 g l−1) than the PQQ-44 strain (0.15 g l−1), whose chemical compositions&#xd;
also differ. Remarkably, PQQ-44 EPS contains large amounts of fucose, a sugar used in high-value&#xd;
biotechnological applications. Furthermore, the genome of strain PQQ-42 contained a large nonribosomal&#xd;
peptide synthase (NRPS) cluster with a previously unknown genetic structure. The synthesis&#xd;
of enzymes and other bioactive compounds were also identified, indicating that PQQ-42 and PQQ-44&#xd;
could have biotechnological applications.</dc:description>
