Query: NC_011726:3205278 Cyanothece sp. PCC 8801, complete genome Lineage: Cyanothece; Cyanothece; ; Chroococcales; Cyanobacteria; Bacteria General Information: This strain was isolated from rice fields in Taiwan. Photosynthesis. The cells contain in, addition to chlorophyll and phycobilins, phycoerythrin, a pigment that allows the absorption of light from parts of the spectrum not utilized by many other of photosynthetic organisms.

General Information: Trichodesmium erythraeum strain IMS101 was isolated from the North Carolina coast in 1992 and grows in straight filaments. Filamentous marine cyanobacterium. This filamentous marine cyanobacterium is a nitrogen-fixing organism that contribues a significant amount of the global fixed nitrogen each year. These bacteria are unusual in that nitrogen fixation takes place in a differentiated cell called the diazocyte which is different from the nitrogen-fixing differentiated cell (heterocyst) found in other cyanobacteria. The diazocyte is developed in order to protect the oxygen-sensitive nitrogenases and includes a number of changes including production of more membranes and down-regulation of photosynthetic activity during times of peak nitrogen fixation (noontime). This organism gives the Red Sea its name when large blooms appear and is one of the organisms most often associated with large blooms in marine waters.
