Query: NC_010382:3783879 Lysinibacillus sphaericus C3-41, complete genome Lineage: Lysinibacillus sphaericus; Lysinibacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria General Information: Lysinibacillus sphaericus C3-41 was isolated from a mosquito breeding site in China. This organism is highly toxic to Culex species of mosquito. Lysinibacillus sphaericus, formerly Bacillus sphaericus, is a common environmental organism which produces an insecticidal toxin similar to that produced by Bacillus thuringiensis. Lysinibacillus sphaericus produces two proteins during sporulation which accumulate in parasporal crystalline inclusions. These proteins bind in the gastric cavitiy and midgut of the larvae causing disruption of feeding by the infected host and death.

General Information: This strain was isolated in 1924 from garden soil in Connecticut, USA, by E. Wyer and L. Rettger. It is one of the best studied solventogenic clostridia. 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. This organism is a benign saccharolytic and proteolytic soil bacterium capable of producing a number of organic solvents (solventogenic bacterium) through fermentation of various organic compounds. acetobutyricum were isolated by Chaim Weizman during the World War I and used to develop industrial starch-based acetone, butanol and ethanol fermentation processes.
