Occurrence of okadaic acid-producing Prorocentrum lima on the Sanriku coast, northern Japan.
Prorocentrum lima was found to be distributed on the surface of the algae, Sargassum confusum and Carpopeltis flabellata collected at the Sanriku coast, northern Japan. Chemical analysis of cultured cells revealed that Sanriku strains of P. lima produce okadaic acid, a toxin responsible for diarrhetic shellfish poisoning. The Sanriku strain grew well in T1 medium at 15 degrees C at which tropical strains do not grow, indicating that it is a local strain which adapts to cooler environments.
