Photoassimilation of organic compounds by autotrophic blue-green algae.
Four obligately photoautotrophic blue-green algae were shown to assimilate acetate. This reaction was light dependent and was greatly decreased in the absence of carbon dioxide. Acetate was incorporated mainly into the ethanol extractable (lipid) fraction of the organisms and into the protein fraction. Only four amino acids (glutamate, proline, arginine, leucine) were significantly radioactive ...
متن کاملRole of reduced exogenous organic compounds in the physiology of the blue-green bacteria (algae): photoheterotrophic growth of an "autotrophic" blue-green bacterium.
The unicellular blue-green bacterium Agmenellum quadruplicatum strain BG-1 was found to be capable of rapid photoheterotrophic growth but unable to grow in the dark on a variety of reduced organic substrates. The generation time on glycerol was 12 h, and on CO(2), 3 h. Glycerol carbon was converted into cellular carbon with a very high efficiency. This high efficiency of carbon conversion, the ...
متن کاملLysis of blue-green algae by myxobacter.
Enrichment from local fishponds led to the isolation of a bacterium capable of lysing many species of unicellular and filamentous blue-green algae, as well as certain bacteria. The isolate is an aflagellate, motile rod which moves in a gliding, flexuous manner; the organism is capable of digesting starch and agar, but not cellulose and gelatin. Its deoxyribonucleic acid base pair composition (p...
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 کاملPteridines 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...
