Abstract: Conversion of dimethyl sulfide (DMS) by a marine phytoplankton, Chattonella antiqua, is discussed. The algae was cultured under light and dark conditions and the cells were harvested by centrifugation to prepare pellets and supernatants. The cell pellets were resuspended in a fresh medium and the 4 fractions were heated at 90℃ for 10 min to inactivate enzyme activities. After adding 6 mM DMS, they were incubated again for two weeks in the light and dark, respectively. It was found by means of capillary electrophoresis that DMS was converted to dimethyl sulfoxide (DMSO) only in the pellet fraction cultured in the light but not in the other 3 fractions. It was therefore considered that the conversion could possibly be a photo-induced oxidation reaction which is mediated by a kind of certain photosensitizing cellular components of the algae.
