Effect of TDA-producing Phaeobacter inhibens on the fish pathogen Vibrio anguillarum in non-axenic algae and copepod systems.

ABSTRACT: The expanding aquaculture industry plays an important role in feeding the growing human population and with the expansion, sustainable bacterial disease control, such as probiotics, becomes increasingly important. Tropodithietic acid (TDA)-producing Phaeobacter spp. can protect live feed, for example rotifers and Artemia as well as larvae of turbot and cod against pathogenic vibrios. Here, we show that the emerging live feed, copepods, is unaffected by colonization of the fish pathogen Vibrio anguillarum, making them potential infection vectors. However, TDA-producing Phaeobacter inhibens was able to significantly inhibit V. anguillarum in non-axenic cultures of copepod Acartia tonsa and the copepod feed Rhodomonas salina. Vibrio grew to 10⁶  CFU ml^-1 and 10⁷
