Optimisation of high value metabolite production from benthic marine dinoflagellate Prorocentrum lima.
… poisoning (DSP) toxins, OA and DTX1, from Prorocentrum lima. The organism is also known to produce peridinin, a carotenoid pigment that has been found to have pharmaceutical potential. Results from this study showed that cultivation of P. lima CCAP 1136/11 was still, although not …

Comparative laboratory study of photoacclimation in selected dinoflagellate and diatom species of the Benguela ecosystem
… catenella, Protoceratium reticulatum, Prorocentrum micans, Prorocentrum triestinum, Gymnodinium zeta) and three diatom species (Chaetoceros sp., C. capense, C. cf. pendulus) were investigated with respect to parameters of P versus E curves (P*m, α* and Ek) and variability in chemical …

Physical constraints on phytoplankton in estuaries and shallow coastal waters
… was dominated by autotrophic dinoflagellates (Prorocentrum micans and Peridifiium trochoideum), manifesting in a sub-surface chlorophyll a maximum. The vertical position of diatom species, bothpelagic and benthic, suggested no dependence on incident irradiance, but seemed solely governed by …

Genetic variability and differentiation in niche components of marine phytoplankton species
… oceanica (19), Cyclococcolithina leptopora (31), Prorocentrum micans (28), Dissodinium lunula (22), Thoracosphaera heimi (20), and Gonyaulax tamarensis (83) were measured in several light and temperature regimes. The data were used to determine the amount of genetic variability and the spatial …

Effect of future CO2 and temperature regimes on phytoplankton community composition, biomass and photosynthetic rates in the western English Channel
… temperature promoted biomass of the HAB species, Prorocentrum minimum in autumn. The results indicate that experimental simulations of year 2100 pCO2 and temperature may significantly modify phytoplankton community structure with a positive feedback on atmospheric CO2 in late summer and no change …

Using cell size to represent phytoplankton diversity in studies of nitrogen dynamics in the southern Benguela
… ciliate, Myrionecta rubra, and a dinoflagellate, Prorocentrum triestinum. The nitrogen uptake rates followed the well observed pattern of high nitrate uptake by large cells and regenerated nitrogen uptake by small cells. Myrionecta rubra had a wide range of nitrate (O₃⁻ ) uptake rates (0.02-0.3 …

Phytoplankton Response to South Louisiana Crude Oil Exposure: Determining Impacts at Individual, Community, Toxin Production, Enzymatic-Activity and Gene-Expression Levels
… species of the GoM, Karenia brevis and Prorocentrum minimum. It was revealed that reactive oxygen species are activated in phytoplankton exposed to crude oil. Phytoplankton species also displayed signs of oxidative stress and damage in their lipid structure under crude oil exposure. A …

Diversidad, abundancia y distribución de dinoflagelados epífitos en la zona intermareal rocosa del Área Natural Protegida Complejo Los Cóbanos, El Salvador
En la presente investigación se caracterizó la diversidad y abundancia de dinoflagelados epífitos en dos sitios del Área Natural Protegida Complejo Los Cóbanos, en la Playa El Faro y Playa La Privada. La abundancia de dinoflagelados no presentó diferencia significativa entre los dos sitios de …

Estudio toxicológico y electrofisiológico de ficotoxinas marinas: Mecanismo excitotóxicos y apoptóticos en cultivos primarios de neuronas
… 1) nuevas ficotoxinas aisladas del dinoflagelado Prorocentrum belizeanum y asociadas con la Intoxicación Diarreica por Mariscos (DSP): Belizeanólido, ácido belizeanólico, belizentrina, ácido 19-epi-okadaico (19-epi-OA) y ácido prorocentroico; y 2) ficotoxinas ampliamente conocidas como palitoxina …

The aggregation of clay minerals and marine microalgal cells : physicochemical theory and implications for controlling harmful algal blooms
… in a mixed culture with the dinoflagellate, Prorocentrum micans, or the diatom, Skeletonema costatum. While the RE's were generally comparable to individual cultures, the RE of either species increased in the presence of the other, especially for K. brevis. Similar results were observed in …
