Query: NC_009617:163466 Clostridium beijerinckii NCIMB 8052 chromosome, complete genome Lineage: Clostridium beijerinckii; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria General Information: Solvent-producing 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. There are also species that can fix molecular nitrogen and thus are important participants in biological turnaround of nitrogen compounds in nature. This species is used to produce industrial solvents.

General Information: This organism is the obligate endosymbiont for the tsetse fly Glossina brevipalpis. As Wigglesworthia brevipalpis resides intracellularly, the resulting co-evolution with its host over millions of years has led to a drastic reduction in the bacterium's genome size, resulting in this its inability to survive outside the host. Tsetse fly endosymbiont. This organism is the obligate endosymbiont for the tsetse fly Glossina brevipalpis, Glossina tachinoides, Glossina palpalis palpalis, and Glossina austeni. The tsetse fly is a vector for African trypanosomes, and is the main transmitter of deadly diseases in animals and humans in Africa. The fly feeds on a restricted diet, exclusively consisting of vertebrate blood, and lacks certain metabolic compounds needed for survival and reproduction. To complement this lack in nutrients, the tsetse fly relies mainly on the intracellular bacterial symbiont, Wigglesworthia glossinidia for its viability and fecundity.
