Query: NC_016630:1462788 Filifactor alocis ATCC 35896 chromosome, complete genome Lineage: Filifactor alocis; Filifactor; Peptostreptococcaceae; Clostridiales; Firmicutes; Bacteria General Information: Filifactor alocis, originally known as Fusobacterium alocis, was first isolated in1985 from the human gingival crevice, and has since been discovered in patients suffering from chronic periodontitis, generalized aggressive, periodontitis and endodontic infections. It has also been isolated from feline soft tissue infections. It is a fastidious, Gram-positive obligately anaerobic rod. Bacteria in periodontal pockets develop complex sessile communities that attach to the tooth surface.

General Information: These cyanobacteria are bluegreen algae that are capable of fixing carbon and nitrogen. 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. Anabaena variabilis is a filamentous heterocyst-forming cyanobacterium that fixes nitrogen and CO2 using the energy of sunlight via oxygen-evolving plant-type photosynthesis. In addition, this organism has been studied extensively for the production of hydrogen using solar energy.
