Ultrastructure 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...
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 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 کاملViability of lyophilized cyanobacteria (blue-green algae).
Lyophilizatin of 13 cyanobacterial cultures belonging to seven genera was attempted in a variety of suspending substances. All organisms survived lyophilization when suspended in lamb serum. Some of the organisms could be successfully lyophilized in horse serum, beef serum, fetal bovine serum, or human ascites fluid. With the exception of Nostoc muscorium, none of the organisms survived lyophil...
