The paralytic shellfish toxin producing dinoflagellate Gymnodinium catenatum is a globally distributed species and often forms massive blooms. However, the physiological and molecular responses of G. catenatum to nitrate starvation have not been thoroughly investigated. Our results showed that multiple forms of N could be utilized by G. catenatum under

Effectiveness of coagulants-flocculants for removing cells and toxins of Gymnodinium catenatum
Aquaculture, 2016Abstract Laboratory experiments compared the removal efficiency of cells and toxins of the dinoflagellate Gymnodinium catenatum, using three concentrations of cells and three concentrations of red clay, montmorillonite, clinoptilolite, calcium oxide, calcium hydroxide, aluminium sulfate, chitosan, activated silica, and polyaluminium chloride, as ...

Harmful Algae, 2016
The allelopathic effect of the raphidophyte Chattonella marina var. marina on the dinoflagellate Gymnodinium catenatum was determined. Both species are harmful algal bloom forming algae, produce toxic metabolites, and can co-exist in the environment.

Alexandrium minutum and Gymnodinium catenatum bloom dynamic in the Galician Rías
2022Alexandrium minutum and Gymnodinium catenatum are associated with paralyzing toxins in Galician Rias (NW Spain). This upwelling area supports the mussel culture on suspended ropes (270,000 t year-1). Both autotrophic dinoflagellates produce cysts and have developed toxic episodes and red tides in the Rías due to slow growth in situ from the internal ...

Hydrolysis of hydroxybenzoate saxitoxin analogues originating from Gymnodinium catenatum
Food Chemistry, 2011Abstract The paralytic shellfish poisoning (PSP) toxin producer Gymnodinium catenatum produces several hydrophobic analogues of saxitoxin (STX). These are poorly studied due to their recent discovery and lack of standards. It was previously observed these hydrophobic analogues could be partially hydrolysed, loosing its benzoate moiety during ...

Gymnodinium catenatum Graham (Dinophyceae): morphology and affinities with armoured forms
Phycologia, 1982Abstract Samples of the unarmoured dinoflagellate Gymnodinium catenatum Graham, collected from the plankton during an outbreak of paralytic shellfish-poisoning, were examined with light and electron microscopy. No thecal plates were seen. Instead, a pellicular layer surrounded the cells.

Harmful Algae, 2013
Abstract Four Gymnodinium species have previously been reported to produce microreticulate cysts. Worldwide, Gymnodinium catenatum strains are conservative in terms of larger subunit (LSU) rDNA and internal transcribed spacer region (ITS) sequences, but only limited information on the molecular sequences of other species is available.

Abstract Gymnodinium nolleri Ellegaard et Moestrup sp. ined. (Dinophyceae) strains established from cysts collected at three marine locations in Denmark were compared to Australian and Spanish strains of Gymnodinium catenatum with respect to morphology, molecular characteristics, and content of paralytic shellfish poisoning (PSP) toxins.

The marine dinoflagellate Gymnodinium catenatum is known to produce saxitoxins (STXs) that are responsible for paralytic shellfish poisoning (PSP); however, the genes involved in STX synthesis are insufficiently understood. In the present study, we determined transcriptome sequences of toxic G.
