The best established physical evidence of early life forms are stromatolites which have been dated to 3.3–3.5 × 109 (Awramik et al., 1983; Schopf and Walter, 1987; Schopf, 1993). Although the phototrophic obligatory anaerobes belonging to the genus Chloroflexus can make laminated microbial mats similar to that seen in micro fossil records (Awramik et ...

Base editing for reprogramming cyanobacterium Synechococcus elongatus
Metabolic Engineering, 2022Abstract Global climate change demands carbon-negative innovations to reduce the concentration of atmospheric carbon dioxide (CO 2 ). Cyanobacteria can fix CO 2 from the atmosphere and can be genetically reprogrammed for the production of biofuels,

Ultrastructure of a marine Synechococcus possessing spinae
Canadian Journal of Microbiology, 1981Two Chesapeake Bay isolates of unicellular cyanobacteria belonging to the genus Synechococcus are described. Unicellular cyanobacteria are suspected to be important primary producers in estuarine and marine waters. One isolate (P-11-16) fluoresces red and forms green colonies. The other isolate (P-11-17) fluoresces orange and forms red colonies. Their

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.

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 ...

Abstract The nucleotide sequence of the txlA gene was determined (Collier, Grossman, 1995) from a genomic clone isolated from the cyanobacterium Synechococcus sp. strain PCC7942 (GenBank accession number U05044). The sequence predicts a protein of 191 amino acids, with an isolelectric point of 4.2.

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

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 ...
