Query: NC_004193:375416 Oceanobacillus iheyensis HTE831, complete genome
Lineage: Oceanobacillus iheyensis; Oceanobacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: This organism is extremely salt tolerant and alkaliphilic and has a number of hydrogen, sodium and potassium transporters to deal with these extreme environments. This organism was isolated from deep sea mud (1050 m) from the Iheya ridge near Okinawa, Japan in 1998.
Subject: NC_016047:2150000 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.
