Poisoning by blue-green algae occurs after an algal "bloom" caused by warm weather and algal concentration. On death or disintegration, the algae release liver toxins and neurotoxins (fast death factor). Although deaths are common in animal exposures, human exposures have been limited to various allergic reactions, mild liver enzyme elevation, and ...

Ultrastructure of Blue-Green Algae
Journal of Bacteriology, 1969Two freshwater blue-green algae, Tolypothrix tenuis and Fremyella diplosiphon , and an oscillatorialike marine alga, were found to possess structures on the photosynthetic lamellae which appear to correspond to the phycobilisomes of red algae. These homologous structures are important because

Veterinary Clinics of North America: Equine Practice
Blue green algae cyanotoxins have become increasingly more prevalent due to environmental, industrial, and agricultural changes that promote their growth into harmful algal blooms. Animals are usually exposed via water used for drinking or bathing, though specific cases related to equines are very limited.

Archives of Microbiology, 1976
The isolation of a halophilic blue-green alga, Aphanothece halophytica, from Great Salt Lake is described. The organism was cultured from waters with salinities up to saturated NaC1 (about 30% w/v). It has an optimum salinity for growth of about 16% NaC1, but can grow very slowly even in saturated NaC1.

Hydrocarbons in green and blue-green algae
Folia Microbiologica, 1982Liquid column chromatography and thin-layer chromatography were used to determine the total content of hydrocarbons and gas chromatography was used to evaluate composition of hydrocarbons in green algae (Chlorella kessleri, C. vulgaris, Chlorella sp., Scenedesmus acutus, S. acuminatus, S.

Archiv f�r Mikrobiologie, 1972
Mesosome-like, unit-membrane structures are clearly defined in the blue-green algae, Spirulina and three strains of Synechococcus, after osmium or potassium permanganate fixation and observation with the electron microscope. The membranous structures are distinct from the photosynthetic membranes and, in the case of Spirulina, are frequently observed ...

Respiration in Blue-Green Algae
Journal of Bacteriology, 1969The low rate of endogenous respiration exhibited by the blue-green algae Anacystis nidulans and Phormidium luridum was not increased by the addition of respiratory substrates. However, endogenous respiration was inhibited by low concentrations of cyanide and by high carbon monoxide tensions ...

Nature, 1965
Richter1 and Fewson et al.2 have both reported that fructose diphosphate (FDP) aldolase activity could not be demonstrated in blue-green algae, especially Anacystis nidulans. A peculiar steady-state growth condition induced by uric acid as sole nitrogen source and characterized as a severe nitrogen deficiency has been found in a marine species of blue ...

Blue-green algae, or Cyanophyta (cyan = blue; phyton = plant), are found in a wide variety of environments. They occur in marine and fresh water, on and in soil, and on wet stones, cement, and plant pots. Some can withstand the temperatures of hot springs, others the cold of arctic pools.

The blue-green algae represent a unique stage in the evolution of plant life. The cyanophyta are clearly procaryotic organisms and so they might well be called blue-green bacteria. However they are the only procaryotes able to produce oxygen from water so their photosynthetic activity is like that of the higher plants (Krogmann, 1973).
