Query: NC_014624:2668157 Eubacterium limosum KIST612 chromosome, complete genome
Lineage: Eubacterium limosum; Eubacterium; Eubacteriaceae; Clostridiales; Firmicutes; Bacteria
General Information: Eubacterium limosum KIST612 is an acetogenic bacterium isolated from an anaerobic digester and has a high growth rate on synthesis gas (CO; carbon monoxide) using it as a sole energy source. This organism produces acetate as well as butyrate and ethanol as fermentation products from syngas. Therefore, E. limosum KIST612 has been considered for a model strain for bioenergy production from syngas (obtained from biomass).
Subject: NC_009012:3653111 Clostridium thermocellum ATCC 27405, complete genome
Lineage: Clostridium thermocellum; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria
General Information: This strain is a well studied producer of endoglucanase and several restriction endonucleases. Thermophilic cellulose degrading bacterium. 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. Some species are capable of producing organic solvents (acetone, ethanol, etc,), molecular hydrogen and other useful compounds. This organism is a thermophilic anaerobe that produces an extracellular enzyme system capable of degrading crystalline cellulose to soluble sugars that are further utilized as the carbon source for growth.
