Na+H+ exchange in the cyanobacterium Synechococcus 6311
Biochemical and Biophysical Research Communications, 1984The cyanobacterium Synechococcus 6311 adapts to grow in 0.6 M NaCl by developing an efficient system for sodium extrusion. In the present investigation cells loaded with NaC1 were subjected to a large dilution. Changes in fluorescence quenching of acridine orange as a function of transmembrane Na+ gradients provide evidence that Na+/H+ exchange ...

Acetate uptake by the unicellular cyanobacteria Synechococcus and Aphanocapsa
Archives of Microbiology, 1977Acetate uptake by strains of Synechococcus and Aphanocapsa in short experiments required light, and was strongly inhibited by m-dichlorocarbonyl cyanide phenylhydrazone and dichlorophenyl dimethyl urea. Acetate carbon was distributed in amino acids and in the acyl portion of lipids in the same way as during growth experiments when CO2 was available ...

The ferredoxin:sulphite reductase gene from Synechococcus PCC7942
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1993The structural gene of the ferredoxin:sulphite reductase (EC 1.8.7.1) from the cyanobacterium Synechococcus PCC7942 (formerly 'Anacystis nidulans') was cloned and sequenced. The gene termed 'sir' was detected by heterologous Southern hybridisation with the structural gene cysI from Escherichia coli encoding the iron-sulphur haemoprotein of the NADPH ...

The synthesis of elemental selenium particles by Synechococcus leopoliensis
Applied Microbiology and Biotechnology, 2013Exposure of Synechococcus leopoliensis to selenite in the light resulted in orange-colored granules associated with the cells. No such particles were made in dark grown cells or when selenite was replaced by selenate. Light and scanning electron microscopy revealed that the particles formed inside the cells. Furthermore, these were easily extracted and

A New Synechococcus Cyanophage from a Reservoir in Korea
Virology, 1994A unicellular cyanobacterium (Synechococcus) and its cyanophage were both isolated from a reservoir in Korea. Although morphologically similar to AS-1, the cyanophage differs from cyanophage AS-1 in some respects. The burst size in the light is approximately 100 plaque-forming units (PFU)/cell.

The new microbiologica, 1998
During the last oceanographic cruise carried out in the Straits of Magellan (April 1995), a serological approach was used in order to determine the distribution and composition of the picophytoplankton community with respect to two cyanobacteria species, Synechococcus sp.

Plant Molecular Biology, 1994
Two open reading frames denoted as cpcE and cpcF were cloned and sequenced from Synechococcus sp. PCC 6301. The cpcE and cpcF genes are located downstream of the cpcB2A2 gene cluster in the phycobilisome rod operon and can be transcribed independently of the upstream cpcB2A2 gene cluster. The cpcE and cpcF genes were separately inactivated by insertion

Physiological diversity and niche adaptation in marine Synechococcus
2003During the twenty years or so since the discovery of tiny photosynthetic cells of the genus Synechococcus in marine oceanic systems, a tremendous expansion of interest has been seen in the literature pertaining to these organisms. The fact that they are ubiquitous and abundant in major oceanic regimes underlies their ecological importance as ...

The work is devoted to the substantiation of the use of cyanobacteria as a test-object for the screening of new antiviral medicinal substances. Clear correlation of experimental substances??? toxicity between culture of S. cedrorum and control test-cultures which are usually used in the investigation of new synthesized substances??? properties is shown.

Biotechnological Applications of Cyanobacteria: Synechocystis and Synechococcus Strains
Cyanobacteria as phototrophic microorganisms bear great potential for biotechnological application and a truly sustainable bioeconomy. Besides production of biomass and natural compounds, CO2-based production of diverse value-added compounds with engineered strains enjoys ever-growing interest.Paul, Bolay +2 more
