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.

Glycolate dehydrogenase in green algae
Archives of Biochemistry and Biophysics, 1970Abstract Glycolate dehydrogenase was partially purified from Chlamydomonas by Triton X-100 extraction from the cells followed by ammonium sulfate fractionation. The enzyme had no oxidase activity. No glyoxylate formation occurred in the absence of the artificial electron acceptors, dichloroindophenol or phenazine methosulfate.

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

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.

Xylan of Siphonaceous Green Algae
Nature, 1960COMPARATIVELY little is known at present about the chemical nature of the cell wall constituents of siphonous green algae, especially that of the non-septate groups. Although the cell wall of the algae belonging to Bryopsidaceae, Caulerpaceae and Codiaceae has been stated to consist for the most part of callose (a name given originally to a ...

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 ...

[FeFe]-hydrogenases from green algae
2018Algal hydrogenases are among to the most efficient hydrogen (H2) generating biocatalysts and use low-potential electrons from the photosynthetic light reactions. Thereby, photobiological H2 evolution by eukaryotic microalgae represents a sustainable alternative to the energy intensive industrial production of H2 based on fossil fuels.

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 ...
