Hydrocarbons in green and blue-green algae

Folia Microbiologica, 1982
Liquid 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.

Blue-green algae poisoning

The Journal of Emergency Medicine, 1985
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, 1969
Two 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

Blue Green Algae

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.

Respiration in Blue-Green Algae

Journal of Bacteriology, 1969
The 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 ...

Halophilic-blue-green algae

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.

Aldolase in Blue-green Algae

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 ...

Mesosomes in blue-green algae

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 ...

Nitrogen chlorosis in blue-green algae

Archiv f�r Mikrobiologie, 1969
Nitrogen deficient Anacystis nidulans contained normal levels of chlorophyll-a and carotenoids but did not contain any phycocyanin. These organisms also contained large amounts of polysaccharide. The addition of nitrate to a deficient culture resulted in the recovery of normal pigmentation over a period of several hours.

Urease Activity in Blue-Green Algae

Science, 1966
The apparent enzymatic hydrolysis of urea has been detected in whole blue-green algae and in cell extracts. Urease is present as an intracellular component in cultures in which no bacterial contaminants are found. The activity in the cells was recovered from the extracts.
