from extracellular to intracellular: the establishment of mitochondria and chloroplasts.	paracoccus and rhodopseudomonas are unusual among bacteria in having a majority of the biochemical features of mitochondria; blue-green algae have many of the features of chloroplasts. the theory of serial endosymbiosis proposes that a primitive eukaryote successively took up bacteria and blue-green algae to yield mitochondria and chloroplasts respectively. possible characteristics of transitional forms are indicated both by the primitive amoeba, pelomyxa, which lacks mitochondria but contains a ...	1979	36620
[characteristics of the proteins of unicellular organisms as potential components of ecological life-support systems].	a comparative characterization of the biological value of proteins from green and blue-green algae, bacteria, and microbial coenosis of straw mineralizing active sludge is given with respect to the fractional composition of total protein, its amino acid composition, and affinity for proteolytic enzymes in vitro. the above microorganisms have an adequate amino acid composition, a high content of essential amino acids, and differ in their content of readily soluble proteins. the presence of protei ...	1979	36502
role of phycobilin pigments in photosynthesis.	experimental data on possible role of phicobilliprotein (phbp) in photosynthesis are analysed. it is concluded that the widely spread notion about phbp only as the light-gathering pigments which transfer the energy to chlorophyll, turned to be insufficiently substantiated experimentally until recently. at the same time the discovered ability of phbp for reversible redox transformations together with the new data on the nature of fluorescence of blue-green algae and phbp localization in the cell ...	1977	19089
penicillinase (beta-lactamase) formation by blue-green algae.	beta-lactamase (penicillinase) activity was found in a number of strains of blue-green algea. in some cases, this enzyme permitted algae to overcome the inhibitory effects of penicillin. production and localization of beta-lactamase were studied in a unicellular species, coccochloris elabens (strain 7003), and in a filamentous, nitrogen-fixing anabaena species (strain 7120). when cells were grown in a neutral medium with nano3 as n source, the ph rose during growth; at a ph of about 10, most of ...	1977	15530
influence of sewage discharge on nitrogen fixation and nitrogen flux from coral reefs in kaneohe bay, hawaii.	nitrogen fixation was investigated in kaneohe bay, oahu, hawaii, a subtropical eutrophic estuary, by using the acetylene reduction technique on algal samples. no active, planktonic, n2-fixing blue-green algae or bacteria were observed. however, calothrix and nostoc capable of fixing n2 were cultured from navigational buoys and dead coral heads. nitrogen fixation associated with these structures was greater in the middle sector than in the south and north sectors of the estuary. experiments demon ...	1976	7198
presence of two subunit types in ribulose-1,5-bisphosphate carboxylase from blue-green algae.		1976	3179
some thermodynamic and kinetic properties of the primary photochemical reactants in a complex from a green photosynthetic bacterium.	we have examined the bacteriochlorophyll reaction-center complex of chlorobium limicola f. thiosulfatophilum, strain tassajara. our results indicate that the midpoint potential of the primary electron donor bacteriochlorophyll of the reaction center is +250 mv at ph 6.8, while that of cytochrome c-553 is +165 mv. there are two cytochrome c-553 hemes per reaction center, and the light-induced oxidation of each is biphasic (t1/2 of less than 5 mus and approximately 50 mus). we belive that this ind ...	1976	2322
effect of nadp on light-induced cytochrome changes in membrane fragments from a blue-green alga.	the effect of nadp+ on light-induced steady-state redox changes of membrane-bound cytochromes was investigated in membrane fragements prepared from the blue-green algae nostoc muscorum (strain 7119) that had high rates of electron transport from water to nadp+ and from an artificial electron donor, reduced dichlorophenolindophenol (dciph2) to ndap+. the membrane fragments contained very little phycocyanin and had excellent optical properties for spectrophotometric assays. with dciph2 as the elec ...	1976	2320
