Marine biofilms: cyanobacteria factories for the global oceans
mSystemsMarine biofilms were newly revealed as a giant microbial diversity pool for global oceans. However, the cyanobacterial diversity in marine biofilms within the upper seawater column and its ecological and evolutionary implications remains undetermined ...

, 2022 Although numerous marine prokaryotes dwelling in the sunlit layer of oceans can exploit solar energy, cyanobacteria are the only ones to perform oxygenic photosynthesis and to produce organic carbon, a critical process that sustains the whole marine trophic web.

Origin of marine planktonic cyanobacteria [PDF]
Scientific Reports, 2015 AbstractMarine planktonic cyanobacteria contributed to the widespread oxygenation of the oceans towards the end of the Pre-Cambrian and their evolutionary origin represents a key transition in the geochemical evolution of the Earth surface. Little is known, however, about the evolutionary events that led to the appearance of marine planktonic ...

Unraveling the genomic mosaic of a ubiquitous genus of marine cyanobacteria [PDF]
Genome Biology, 2008 Abstract Background The picocyanobacterial genus Synechococcus occurs over wide oceanic expanses, having colonized most available niches in the photic zone. Large scale distribution patterns of the different Synechococcus clades (based on 16S rRNA gene markers) suggest the occurrence of two major ...

Nitrogen fixation by marine cyanobacteria
Trends in Microbiology, 2011 Discrepancies between estimates of oceanic N(2) fixation and nitrogen (N) losses through denitrification have focused research on identifying N(2)-fixing cyanobacteria and quantifying cyanobacterial N(2) fixation. Previously unrecognized cultivated and uncultivated unicellular cyanobacteria have been discovered that are widely distributed, and some ...

Marine Benthic Cyanobacteria Contain Apoptosis-Inducing Activity Synergizing with Daunorubicin to Kill Leukemia Cells, but not Cardiomyocytes [PDF]
Marine Drugs, 2010 The potential of marine benthic cyanobacteria as a source of anticancer drug candidates was assessed in a screen for induction of cell death (apoptosis) in acute myeloid leukemia (AML) cells.

Anoxia-adapted cyanobacteria in a marine blue hole [PDF]
Applied and Environmental MicrobiologyVertical transmission of marine particles brings ocean surface cyanobacteria into the deep ocean, where heterotrophic cyanobacterial lineages probably evolve to adapt to new environments even in oxygen-depleted zones.

Current Research in Green and Sustainable Chemistry, 2021 An integrated approach on uranium adsorption and emulsification of oils was evaluated using extracellular polysaccharides (EPS) of a marine unicellular cyanobacterium Synechococcus elongatus BDU130911. EPS gel of S. elongatus BDU130911 was able to adsorb

Bioprospecting Sponge-Associated Marine Cyanobacteria to Produce Bioactive Compounds. [PDF]
Toxins (Basel), 2020 Marine cyanobacteria are considered a prolific source of bioactive natural products with a range of biotechnological and pharmacological applications. However, data on the production of natural compounds from sponge-associated cyanobacteria are scarce ...
