Cyanobacteria evolved the oxygenic photosynthesis to generate organic matter from CO 2
and sunlight, and they were responsible for the production of oxygen in the Earth's …

Picocyanobacteria of the genus Synechococcus (together with Cyanobium and
Prochlorococcus) have captured the attention of microbial ecologists since their description …

Background Cyanobacteria are the major prokaryotic primary producers occupying a range
of aquatic habitats worldwide that differ in levels of salinity, making them a group of interest …

Abstract Background The Black Sea is the largest brackish water body in the world, although
it is connected to the Mediterranean Sea and presents an upper water layer similar to some …

Synechococcus cyanobacteria are ubiquitous and abundant in the marine environment and
contribute to an estimated 16% of the ocean net primary productivity. Their light-harvesting …

Motivation metal-binding proteins have a central role in maintaining life processes. Nearly
one-third of known protein structures contain metal ions that are used for a variety of needs …

Background Cold environments dominate the Earth's biosphere and microbial activity drives
ecosystem processes thereby contributing greatly to global biogeochemical cycles. Polar …

In marine and freshwater oxygen-deficient zones, the remineralization of sinking organic
matter from the photic zone is central to driving nitrogen loss. Deep blooms of photosynthetic …

Marine Synechococcus, a main group of picocyanobacteria, has been ubiquitously
observed across the global oceans. Synechococcus exhibits high phylogenetical and …

Seas and oceans are a global reservoir of antibiotic resistance genes (ARGs). Only a few
studies investigated the dynamics of ARGs along the water column of the Black Sea, a …
