SYNOPSIS.Gyrodinium cohnii , a marine heterotrophic dinoflagellate, was cultured at 35 C in a medium supplemented with yeast extract and finally in a defined medium. Vitamin B 12 , not required at 30 C or lower, caused marked stimulation at 35 C used in combination with yeast extract or tryptophan + proline. Folic acid and possibly other vitamins may also be stimulatory at the elevated temperature. Ecological implications and applications to bioassays are discussed.
