Intracellular bacteria: the origin of dinoflagellate toxicity.

摘要: Dinoflagellate blooms of the same species have been registered either as toxic or nontoxic and, in latter case, toxicity may be different types. A hypothesis has formulated according to which bacteria having some way taken part toxin formation are inside dinoflagellate cell nutritive liquid. The presence intracellular those microorganisms studied mainly material from cultures, a few sea, and several strains were isolated species. Experiments with crossed inoculations shown that bacterial strain Gonyaulax tamarensis caused cells other become toxic. From clonal cultures Prorocentrum balticum, Glenodinium foliaceum, Gyrodinium instriatum, after inoculation strain, obtained whose extracts showed kind G. tamarensis. No action could found form assayed strains. interference metabolism dinoflagellates must main cause their toxicity.
