The YTX profiles of the isolated strains were dominated by homo-YTX, YTX and a hydroxylated YTX analogue with retention time different 45-OH-YTX. Several planktonic species are toxic and are sometimes abundant enough to colour water and cause the phenomenon called red tide, which may kill fish and other animals.Humans may be poisoned by eating mussels or other shellfish that have ingested large quantities of Gonyaulax catenella.

Studies of phytoplankton are essential to understand food chain dynamics in aquatic ecosystems (Sieburth and Davis, 1982).In oligotrophic waters, the base of the food chain is composed of very small cells in the size range 0.2–2 μm [‘picoplankton' (Sieburth et al., 1978)] and the microbial loop dominates the pelagic food web (Fenchel, 1988).

YTXs are polyether phycotoxins first isolated in Japan from the scallop Patinopecten yessoensis (Murata et al., 1987).YTXs are produced by a number of dinoflagellates including Lingulodinium polyedrum, Protoceratium reticulatum and Gonyaulax spinifera (Satake et al., 1999; Paz et al., 2004, 2008; Álvarez et al., 2011).More than 90 different YTX analogues have been identified in … 106, 144pp. La pàgina va ser modificada per darrera vegada el 19 jul 2020 a les 13:35.
