Identification of Volatiles of the Dinoflagellate <i>Prorocentrum cordatum</i>

The dinoflagellate <i>Prorocentrum cordatum</i>, often called <i>P. minimum</i>, is a potentially toxic alga found in algal blooms. Volatile compounds released by the alga might carry important information, e.g., on its physiological state, and may act as chemical messengers....

description The dinoflagellate <i>Prorocentrum cordatum</i>, often called <i>P. minimum</i>, is a potentially toxic alga found in algal blooms. Volatile compounds released by the alga might carry important information, e.g., on its physiological state, and may act as chemical messengers. We report here the identification of volatile organic compounds emitted by two strains, xenic <i>P. cordatum</i> CCMP 1529 and axenic <i>P. cordatum</i> CCMP 1329. The volatiles released during culture were identified despite their low production rates, using sensitive methods such as open-system-stripping analysis (OSSA) on Tenax TA desorption tubes, thermodesorption, cryofocusing and GC/MS-analysis. The analyses revealed 16 compounds released from the xenic strain and 52 compounds from the axenic strain. The majority of compounds were apocarotenoids, aromatic compounds and small oxylipins, but new natural products such as 3,7-dimethyl-4-octanolide were also identified and synthesized. The large difference of compound composition between xenic and axenic algae will be discussed.
