Characterization of biofilm-forming marine bacteria and their effect on attachment and germination of algal spores

摘要: In this work, 37 bacterial strains isolated from biofouling of marine organisms and the Museum Heterotrophic Bacteria National Scientific Center Marine Biology were studied. The identified based on their phenotypic characteristics fatty acid composition cell wall lipids. Members genus Pseudoalteromonas prevailed both in associated microflora two dinoflagellate clones biofilms hydrobionts. Associated included also members CFB cluster, Bacillus, Sulfitobacter, Acinetobacter, Shewanella, Psychrobacter. A considerable portion (48.6%) exhibited antimicrobial activity. Antifouling activity against algal spores was studied using single-species Ulva lactuca и Undaria pinnatifida, algae most common Sea Japan. Strong inhibitory effect attachment observed for 75 51% strains, respectively. Attached were, however, less sensitive to action biofilms. Species specificity response bacteria shown, with a strain having different species. Biotechnologically promising determined, which high macroalgae could probably be used as producers antifouling substances components coatings. No relation found between source isolation. Our results indicate wide occurrence among hydrobionts demonstrate extent complexity diversity relations spores.
