Query: NC_010320:881351 Thermoanaerobacter sp. X514 chromosome, complete genome
Lineage: Thermoanaerobacter; Thermoanaerobacter; Thermoanaerobacteraceae; Thermoanaerobacterales; Firmicutes; Bacteria
General Information: This strain was isolated by anaerobic enrichment culture from a deep subsurface sample (2000 m below the surface) taken from a core hole at the Piceance Basin, Colorado, USA. It can use a variety of electron donors, including glucose, acetate, hydrogen and xylose while reducing iron, chromium and uranium at 60 degrees C.
Subject: NC_019771:4459000 Anabaena cylindrica PCC 7122, complete genome
Lineage: Anabaena cylindrica; Anabaena; Nostocaceae; Nostocales; Cyanobacteria; Bacteria
General Information: Country: United Kingdom; Environment: Ponds; Isolation: Water, most likely pond, Cambridge, UK, 1939; Temp: Mesophile. They form long filaments and can be found worldwide in various aquatic environments as well as some terrestrial ones. These bacteria can form a variety of differentiated cell types, including spore-like cells (akinetes), small motile filaments (hormongia) and most importantly, heterocysts that are nitrogen-producing cells. The heterocyst produces multiple layers outside of its cell wall, shuts down photosystem II in order to inhibit oxygenic photosynthesis and ramps up metabolism in order to use up the oxygen present. Heterocysts donate fixed nitrogen compounds as amino acids to neighboring cells and in return receive a photosynthetically produced carbon source such as sucrose. These organisms produce toxic blooms in aquatic environments that are harmful or fatal to animals and humans due to the various cyanotoxins they produce.
