The Dinophysis genus includes both phototrophic and heterotrophic species. D. acuminata is one of several phototrophic species of Dinophysis classed as toxic, as they produce okadaic acid which can cause diarrhetic shellfish poisoning (DSP). Okadiac Dinophysis toxins (DTXs) emerged as a major risk since the 1970s, it was not until the recent cultivation of D. acuminata in the laboratory [5] that it became possible to undertake physiological studies of the Dinophysis Acuminata What is Dinophysis acuminata? Dinophysis acuminata is a marine planktonic (free-floating) microalgal species (dinoflagellate).

D. acuminata was isolated from Danish coastal waters and cultivated using the mixotrophic ciliate Mesodinium rubrum as prey. The roles of food uptake and photosynthesis for the growth and survival of D. acuminata were studied. Dinophysis acuminata and Teleaulax spp. were restricted to the upper 9 m but M. rubrum was found down to 20 m depth. This study offers circumstantial evidence for the interdependency between the three taxa in nature.

Distribution Dinophysis acuminata is widely distributed from cold to warm waters of both hemispheres. Its presence in the Mediterranean status D. skagii Paulsen has been observed forming couplets with D. acuminata, and is probably a 'small cell' in its life cycle 2014-09-26 13:03:20 Janina Kownacka - Added media: Dinophysis acuminata_9.jpg 2014-06-02 10:46:36 Regina Hansen - Updated media metadata for Dinophysis acuminata_8.png 2014-06-02 10:44:58 Regina Hansen - Updated media metadata for Dinophysis acuminata_8.png While toxic species of Dinophysis such as D. acuminata have a single gene for LSU rRNA, non-toxic species seem to have two distinct classes of LSU rRNA. The difference between these two classes was a 70 bp deletion, indicating the shorter product might be a pseudogene. Dinophysis is one genera responsible for Diarrhetic shellfish poisoning (DSP), a global illness with incidences of outbreak or high toxicity occurring in North America, western Europe, east and southeast Asia, South America, Latin America, South Africa, New Zealand, and Australia.
