Query: NC_014364:2246524 Spirochaeta smaragdinae DSM 11293 chromosome, complete genome
Lineage: Spirochaeta smaragdinae; Spirochaeta; Spirochaetaceae; Spirochaetales; Spirochaetes; Bacteria
General Information: Country: Congo; Environment: Oil fields; Isolation: Oil field of Congo, Africa; Temp: Mesophile; Temp: 35C. Spirochaeta smaragdinae was isolated from an oil field in Central Africa. The species is Gram-negative, motile, obligately halophilic and strictly anaerobic and is of interest because it is able to ferment numerous polysaccharides.
Subject: NC_015275:1 Clostridium lentocellum DSM 5427 chromosome, complete genome
Lineage: Cellulosilyticum lentocellum; Cellulosilyticum; Lachnospiraceae; Clostridiales; Firmicutes; Bacteria
General Information: Isolation: River sediment with paper mill waste; Temp: Mesophile; Temp: 40C; Isolation:river sediment with paper mill waste; Country:United Kingdom: River Don, Scotland. 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. This is a cellulolytic bacterium isolated from river sediment containing paper-mill waste.
