[Algicidal effect of (2-isobutoxyphenyl) amine on Alexandrium tamarense].

Wei sheng wu xue bao = Acta microbiologica Sinica, 2016
A strain named BS01 showed strong algicidal activity to Alexandrium tamarense and we got algicidal compound (2-isobutoxyphenyl) amine from BS01 to study its algicidal effect on A. tamarense.We studied the algicidal mechanism of (2-isobutoxyphenyl) amine on photosynthetic process, antioxidant enzyme activities and morphological change of A.

The impact of associated bacteria on morphology and physiology of the dinoflagellate Alexandrium tamarense

Harmful Algae, 2015
Abstract Despite their potential impact on phytoplankton dynamics and biogeochemical cycles, biological associations between algae and bacteria are still poorly understood. The aim of the present work was to characterize the influence of bacteria on the growth and function of the dinoflagellate Alexandrium tamarense.

Differences in expression patterns of photosynthetic genes in the dinoflagellate Alexandrium tamarense

European Journal of Protistology, 2005
In higher land plants, the expression pattern and mechanisms of transcriptional regulation of photosynthetic genes such as chl a/b-binding protein have been well studied. However, details of these mechanisms in dinoflagellates have not been reported.

Nitrate and phosphate supplementation to increase toxin production by the marine dinoflagellate Alexandrium tamarense

Marine Pollution Bulletin, 2006
Alexandrium tamarense toxins have great value in biotechnology research as well as important in connection with shellfish poisoning. The influence of nitrate or nitrate and phosphate supplementation on cell biomass and toxin content were investigated in batch cultures.

Radiobiosynthesis of paralytic shellfish toxins in the dinoflagellate alexandrium tamarense

2014
Paralytic shellfish toxins (PSTs) are a family of neurotoxic alkaloids produced by certain dinoflagellates including strains of Alexandrium tamarense that are found in Hong Kong and South China coastal waters. The frequent occurrence of these toxins in commercial shellfish and other seafood is a serious food safety, economic and environmental problem ...

Effect of antibiotic treatment on toxin production by Alexandrium tamarense.

Biomedical and environmental sciences : BES, 2004
Impact of the presence of bacteria associated with a marine dinoflagellate, Alexandrium tamarense CI01, on the growth and toxin production of the algae in batch culture was investigated.Pronounced changes in the activities of the algal culture were observed when the culture was treated with different doses of a mixture of penicillin and streptomycin.In

Biotransformation of mycosporine like amino acids (MAAs) in the toxic dinoflagellate Alexandrium tamarense

Journal of Photochemistry and Photobiology B: Biology, 2006
Changes in mycosporine-like amino acids (MAAs) induced by the increase of photosynthetically active radiation (PAR) were studied in the toxic dinoflagellate Alexandrium tamarense. Cultures of A. tamarense were maintained at exponential growth under low (25 micromol quanta m(-2)s(-1)) PAR irradiance. The cultures were nutrient enriched and one day later

Inhibition of the Growth of Alexandrium tamarense by Algicidal Substances in Chinese Fir (Cunninghamia lanceolata)

Bulletin of Environmental Contamination and Toxicology, 2009
The wood sawdust from Chinese fir (Cunninghamia lanceolata) exhibited stronger inhibition on the growth of Alexandrium tamarense than those from alder (Alnus cremastogyne), pine (Pinus massoniana), birch (Betula alnoides) and sapele (Entandrophragma cylindricum). The water extract, acetone-water extract and essential oil from fir sawdust were all shown

IDENTIFICATION AND TOXICITY OF ALEXANDRIUM TAMARENSE (DINOPHYCEAE) IN SCOTTISH WATERS¹

Journal of Phycology, 2009
Contamination of shellfish with paralytic shellfish poisoning (PSP) toxins produced by Alexandrium species poses a potential threat to the sustainability of the Scottish aquaculture industry. Routine LM analysis of water samples from around the Scottish coast has previously identified Alexandrium (Dinophyceae) as a regular part of the spring and summer

Stress‐related Responses in Alexandrium tamarense Cells Exposed to Environmental Changes

Journal of Eukaryotic Microbiology, 2013
AbstractOrganisms tend to be sensitive to drastic changes in environmental conditions. For unicellular microorganisms, variations in physico‐chemical conditions are particularly challenging and may result in acclimation, entrance into quiescence, or death through necrotic or autocatalytic pathways.
