Query: NC_011729:812594 Cyanothece sp. PCC 7424 chromosome, complete genome
Lineage: Cyanothece; Cyanothece; ; Chroococcales; Cyanobacteria; Bacteria
General Information: This strain was isolated from a rice field in Senegal. The genome shows that these cells have the ability to store the products of both photosynthesis (glycogen) and nitrogen fixation (cyanophycin) as intracellular inclusion bodies. Unlike some other Cyanothece strains, Cyanothece 7424 appears to be an obligate autotroph.
Subject: NC_010001:4520979 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.
