Query: NC_010382:1020516 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.
Subject: NC_016047:2480921 Bacillus subtilis subsp. spizizenii TU-B-10 chromosome, complete
Lineage: Bacillus subtilis; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: This organism was one of the first bacteria studied, and was named Vibrio subtilis in 1835 and renamed Bacillus subtilis in 1872. It is one of the most well characterized bacterial organisms, and is a model system for cell differentiation and development. This soil bacterium can divide asymmetrically, producing an endospore that is resistant to environmental factors such as heat, acid, and salt, and which can persist in the environment for long periods of time. The endospore is formed at times of nutritional stress, allowing the organism to persist in the environment until conditions become favorable. Prior to the decision to produce the spore the bacterium might become motile, through the production of flagella, and also take up DNA from the environment through the competence system. The sporulation process is complex and involves the coordinated regulation of hundreds of genes in the genome. This initial step results in the coordinated asymmetric cellular division and endospore formation through multiple stages that produces a single spore from the mother cell.
