This study investigated the role of intracellular and extracellular bacteria in the production ofparalytic shellfish toxins by dinoflagellated algal cells. Three strains of the toxic dinoflagellatespecies, Alexandrium tamarense , were purified by external bacteria using penicillin G (Pen.G) at levels of 500 and 1000 p.p.m. Levels of toxicity of the resulting purified dinoflagellatecultures were similar to those of the original strains contaminated with external bacteria,indicating that the external bacteria had no influence on toxicity. No bacterial colony formingunits (cfu) arose from disruption of algal cells derived from penicillin‐treated cultures, indicatingthat intracellular bacteria were not responsible for the toxicity of cultures.
