Query: NC_014654:2101500 Halanaerobium sp. 'sapolanicus' chromosome, complete genome
Lineage: Halanaerobium hydrogeniformans; Halanaerobium; Halanaerobiaceae; Halanaerobiales; Firmicutes; Bacteria
General Information: Environment: Fresh water, Sediment; Temp: Mesophile; Temp: 34 - 42C. Organisms identified in the genus Halanaerobium (also known as Haloanaerobium) were first isolated from the Great Salt Lake in Utah, USA and have since been isolated from diverse saline environments such as oil reserviors, brine-seawater interfaces and hypersaline sediments. These bacteria are extremely salt-tolerant and are able to grow in concentrations of salt as high as 25%.
Subject: NC_004757:427483 Nitrosomonas europaea ATCC 19718, complete genome
Lineage: Nitrosomonas europaea; Nitrosomonas; Nitrosomonadaceae; Nitrosomonadales; Proteobacteria; Bacteria
General Information: Ammonia-oxidizing bacterium. This organism is an obligate chemo-lithoautotroph as it only uses ammonia and carbon dioxide and mineral salts for growth, and is an important part of the global biogeochemical nitrogen cycle. It can derive all energy requirements from the oxidation of ammonia to nitrate, driving global nitrogen from the reduced insoluble form to the oxidized and potentially gaseous form (including NO and NO2 which are greenhouse gases). The energy derived from ammonia oxidation is in turn used to drive carbon fixation. This bacterium also provides plants with a readily available form of nitrogen, is important in wastewater treatment, and may be involved in bioremediation of sites contaminated with toxic compounds.
