Bacterial diversity of Gymnodinium catenatum and its relationship to dinoflagellate toxicity
Gymnodinium catenatum Graham (Dinophyceae) is one of several marine dinoflagellates responsible for outbreaks of paralytic shellfish poisoning (PSP), a problem that is considered to be increasing globally. Bacteria associated with these dinoflagellates have been implicated as potentially involved with the production of PSP toxins, and this study sought to identify whether there was a link betwe...
متن کاملBacterial Associates Modify Growth Dynamics of the Dinoflagellate Gymnodinium catenatum
Marine phytoplankton cells grow in close association with a complex microbial associate community known to affect the growth, behavior, and physiology of the algal host. The relative scale and importance these effects compared to other major factors governing algal cell growth remain unclear. Using algal-bacteria co-culture models based on the toxic dinoflagellate Gymnodinium catenatum, we test...
متن کاملBacterial Community Affects Toxin Production by Gymnodinium catenatum
The paralytic shellfish toxin (PST)-producing dinoflagellate Gymnodinium catenatum grows in association with a complex marine bacterial community that is both essential for growth and can alter culture growth dynamics. Using a bacterial community replacement approach, we examined the intracellular PST content, production rate, and profile of G. catenatum cultures grown with bacterial communitie...
متن کاملGrazing of heterotrophic dinoflagellate Noctiluca scintillans (Mcartney) Kofoid on Gymnodinium catenatum Graham.
A dinoflagellate bloom ("red tide" event) dominated by the toxic Gymnodinium catenatum Graham (Gymnodiniales, Dinophyceae; 99.7%) and the noxious Noctiluca scintillans (Mcartney) Kofoid (Noctilucaceae, Dinophyceae; 0.3%) was observed in Bahia de Mazatlán Bay, México, on 24-26 January 2000. Photographic and microscopic analysis of samples during such an event, allowed us to collect evidence of a...
متن کاملThe toxic dinoflagellate Gymnodinium catenatum: an invader in the Mediterranean Sea
The distribution of the toxic dinoflagellate Gymnodinium catenatum Graham in the Mediterranean Sea was once restricted to the eutrophic waters of the Alborán Sea. In September 1999, this taxon was found for first time in the Algerian basin, being the dominant species at subsurface depths (~1 cell mL–1) associated with low salinity waters. The geographical expansion of this exotic species is not...
