Query: NC_014212:319815 Meiothermus silvanus DSM 9946 chromosome, complete genome
Lineage: Meiothermus silvanus; Meiothermus; Thermaceae; Thermales; Deinococcus-Thermus; Bacteria
General Information: Isolation: Hot spring; Country: Portugal; Temp: Thermophile; Temp: 50C; Habitat: Hot spring. An aerobic, thermophilic, nonmotile Gram-negative bacterium isolated from the hot spring located at the end of a 450 m tunnel and from thermal water piped to a spa at Vizela in northern Portugal. M. silvanus is of special interest as it causes colored biofilms in the paper making industry and may thus be of economic importance as a biofouler. M. silvanus has also been detected in the gut of an invasive wood-boring beetle and in seawater adjacent to a Pacillopora meandrina coral colony at Palmyra Atoll.
Subject: NC_010001:1 Clostridium phytofermentans ISDg, complete genome
Lineage: Lachnoclostridium phytofermentans; Lachnoclostridium; Lachnospiraceae; Clostridiales; Firmicutes; Bacteria
General Information: Isolated from forest soil near the Quabbin Reservoir in Massachusetts, USA. This organism plays an important industrial and ecological role in the anaerobic fermentation of cellulose and produces economically significant levels of acetate and ethanol. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA.
