Query: NC_014654:1 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%.

General Information: Thermomicrobium roseum DSM 5159 was isolated from Yellowstone National Park, USA. Obligate thermophile with unusual cell wall structure. Thermomicrobium roseum is a red-pigmented, rod-shaped, Gram-negative extreme thermophile that possesses both an atypical cell wall composition and an unusual cell membrane that is composed entirely of long-chain 1,2-diols. Analyses of environmental sequences from hot spring environments show that T.roseum displays a low quantity but ubiquitous presence in top layers of microbial mats. Few standard housekeeping genes are found on the megaplasmid, however, it does encode a complete system for chemotaxis including both chemosensory components and an entire flagellar apparatus. T. roseum oxidizes CO aerobically, making it the first thermophile known to do so. In addition, is is propose that glycosylation of its carotenoids plays a crucial role in the adaptation of the cell membrane to this bacterium's thermophilic lifestyle. Because T. roseum is a deep-branching member of this phylum, eventhough this species is not photosynthetic, analysis of the genome provides some insight into the origins of photosynthesis in the Chloroflexi.
