Query: NC_017277:1610391 Synechocystis sp. PCC 6803, complete genome Lineage: Synechocystis; Synechocystis; ; Chroococcales; Cyanobacteria; Bacteria General Information: Photosynthesis. Synechocystis is a genus of cyanobacteria primarily represented by the strain Synechocystis sp. PCC6803. S. sp. PCC6803 lives in freshwater and is capable of both phototrophic growth by oxygenic photosynthesis in sunlight and heterotrophic growth by glycolysis and oxidative phosphorylation during dark periods. It is able to effectively anticipate transitions of light and dark phases by using a circadian clock.

General Information: Obligately chemolithoautotrophic, haloalkaliphilic, mesophilic, microaerophilic and sulfur-oxidizing bacterium. Uses CO2 as a carbon source and reduced inorganic sulfur compounds as an energy source. Utilizes ammonium and urea, but not nitrate or nitrite, as a N-source. Isolated from a full-scale Thiopaq bioreactor in the Netherlands used to remove H2S from biogas. Thioalkalivibrio species are commonly isolated from soda lakes and tend to dominate the microbial community of hypersaline soda lakes. These organisms have a pH optimum of 10 and are able to oxidize hydrogen sulfide to elemental sulfur. Thioalkalivibrio species have also been isolated from sulfide oxidizing bioreactors which remove sulfide from refinery and natural gas.
