Rearing the Colorless Marine Dinoflagellate <i>Cryptothecodinium cohnii</i> for Use as a Biochemical Tool

Abstract

SYNOPSIS. A Puerto Rican isolate of the colorless, marine, superficially athecate, extremely euryhaline, marine dinoflagellate Cryptothecodinium cohnii grows well in simple defined acidic media prepared from a dry mix. Long‐lasting inocula are prepared as biphasic cultures. Refrigerated slants last for months and the organisms resume motility in minutes when slants are flooded with distilled water at room temperature.
