Intestinal colonization potential of turbot (Scophthalmus maximus)- and dab (Limanda limanda)-associated bacteria with inhibitory effects against Vibrio anguillarum
Article Abstract:
Farmed turbot can be protected from vibriosis caused by Vibrio anguillarum by gastrointestinal tractcolonization of organism from the intestinal microflora of turbot (Scophthalmusmaximus) and dab (Limanda limanda). These organisms possess properties that enable them to colonize the fish gastrointestinal tract. Their adhesion and capacity to grow in fish intestinal mucus make them potential protectors of farmed turbot. They exert bectericidal activity by releasing inhibitory metabolites that suppress the growth of Vibrio anguillarum.

Production of eicosapentanoic acid (20:5 n-3) by Vibrio pelagius isolated from turbot (Scophthalmus maximus L.) larvae
Article Abstract:
Bacterial isolates were obtained from turbot larvae, and a representative sample of 14 isolates were chosen for further lipid analysis. Gas chromatographic analysis showed that one isolate contained high levels of eicosapentanoic acid (EPA). The isolate was identified as Vibrio pelagius. Growth of the bacterium at 4 degrees celsius resulted in higher concentrations of EPA in the cellular lipid.This indicates that the bacterium changes its EPA content in response to low temperatures to maintain membrane fluidity.

Comparison of the growth and survival of larval turbot in the absence of culturable bacteria with those in the presence of Vibrio anguillarum, Vibrio alginolyticus, or a marine Aeromonas sp
Article Abstract:
Larval turbot reared on rotifers have varying growth and survival rates in the absence and presence of culturable bacteria. The introduction of Vibrio anguillarum 91079 in the larval culture lowers the mean survival rate of larva. Cultures containing Vibrio alginolyticus or marine Aeromonas species have higher mean survival rates compared to the bacterium-free culture. The higher survival rates are probably due to the lowering of ammonia concentration in the cultures as heterotrophic marine bacteria use ammonia.
