Pteridines in blue green algae.
The presence of a remarkably high concentration of pteridiineS in the blue green alga, Anacystis nidulanis 5, wvas demonstrated by Forrest, van Baalen, and Myers in 1957 (2). A number of (lifferent pteridines were then isolated and ideentifie(l. These included 2-amino-4-hydroxypteridine, 2,6-diamino-4-hydroxypteridline (10), a yellow pteridine assigned the structure 2-aimino-4-hydroxv-6-propion...
متن کاملRespiration in blue-green algae.
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. In addition, the uncouplers dinitrophenol and carbonyl cyanide p-trifluoromethoxyphenylhydrazone both st...
متن کاملUltrastructure of blue-green algae.
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 they contain the phycobilins which are accessory pigments involved in photosynthesis. As in the red alga...
متن کاملBlue-Green Algae Management in Aquaculture
Blue-green algae, scientifically known as Cyano single-celled organisms that grow naturally in fresh not algae (eukaryotes), but are a type of bacteria the ability to synthesize chlorophyll a. Therefore, th sunlight to manufacture carbohydrates from carb process known as photosynthesis. Blue-green al pockets inside vacuoles within their cells that they in regulate their buoyancy in response to ...
متن کاملElectron Microscope Studies on Blue-green Algae
Several species of blue-green algae were studied in thin sections with the electron microscope. Our electron micrographs confirm the view that the cell of blue-green algae is different and simpler in organization than the typical plant or animal cell. On the other hand, the general pattern of ultrastructure is the same as that found in bacteria and Streptomyces. The cell boundary is formed by a...
