Industrial Applications of Dinoflagellate Phycotoxins Based on Their Modes of Action: A Review

Toxins, 2020
Dinoflagellates are an important group of phytoplanktons, characterized by two dissimilar flagella and distinctive features of both plants and animals. Dinoflagellate-generated harmful algal blooms (HABs) and associated damage frequently occur in coastal

Asynchrony of Gambierdiscus spp. Abundance and Toxicity in the U.S. Virgin Islands: Implications for Monitoring and Management of Ciguatera

Toxins, 2021
Ciguatera poisoning (CP) poses a significant threat to ecosystem services and fishery resources in coastal communities. The CP-causative ciguatoxins (CTXs) are produced by benthic dinoflagellates including Gambierdiscus and Fukuyoa spp., and enter reef ...

Geochemical and Seismic Constraints on the Role of Mud Diapirs in Petroleum Migration and Accumulation in the Recôncavo Basin, NE Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT In the Recôncavo Basin, Northeast of Brazil, mud diapirs have been reported for decades, but their role within the basin's petroleum system remains poorly constrained. Here, we combine 2D seismic interpretation, field observations, and organic geochemical analyses of rocks and oil seeps to investigate the relationship between diapirism and ...

LC-MS/MS Method Development for the Discovery and Identification of Amphidinols Produced by Amphidinium

Marine Drugs, 2020
Amphidinols are polyketides produced by dinoflagellates suspected of causing fish kills. Here, we demonstrate a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the identification and quantification of amphidinols (AM).

How nitrogen and phosphorus stoichiometry drive the physiology and photosynthesis of Scrippsiella acuminata (Dinophyceae)

Journal of Phycology, EarlyView.
Abstract Development and growth of microalgae are mainly sustained by two essential nutrients: nitrogen (N) and phosphorus (P). Although single‐nutrient limitation has been extensively studied, the balance between N and P availability remains less explored.

The Distribution and Diversity of Dinoflagellate Cysts in Sediments of Gwatar Bay (Northeast Gulf of Oman)

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2015
Most dinoflagellate produce resting cysts during their sexual lifecycle as well as under unfavorable environmental conditions and from water column settle in the sediments substratum. The evaluation of diversity and distribution of dinoflagellate cysts

Kabirimine, a New Cyclic Imine from an Okinawan Dinoflagellate

Marine Drugs, 2019
On our quest for new bioactive molecules from marine sources, two cyclic imines (1, 2) were isolated from a dinoflagellate extract, inhibiting the growth of the respiratory syncytial virus (RSV).

Amphidinolides B4 and B5, Potent Cytotoxic 26-Membered Macrolides from Dinoflagellate Amphidinium Species

Marine Drugs, 2005
: Two new cytotoxic 26-membered macrolides, amphidinolides B4 (1) and B5 (2), have been isolated from a marine dinoflagellate Amphidinium sp. (strain Y-100), and the structures were elucidated on the basis of detailed analyses of 2D NMR data including ...
