Query: NC_014355:288000 Candidatus Nitrospira defluvii, complete genome
Lineage: Nitrospira defluvii; Nitrospira; Nitrospiraceae; Nitrospirales; Nitrospirae; Bacteria
General Information: This nitrite-oxidizing bacterium was found through enrichment from activated sludge from a municipal wastewater treatment plant. Phylogenetic analysis of 16S rRNA gene sequences revealed that the enriched bacteria represented a novel Nitrospira species closely related to uncultured Nitrospira-like bacteria previously found in wastewater treatment plants and nitrifying bioreactors.
Subject: NC_014976:1174430 Bacillus subtilis BSn5 chromosome, complete genome
Lineage: Bacillus subtilis; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: Bacillus subtilis BSn5 was isolated from Amorphophallus konjac calli tissue culture. Bacilllus subtilis BSn5 could inhibit Erwinia carotovora subsp. carotovora strain SCG1, which causes Amorphophallus soft rot disease and affects Amorphophallus industry development 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.
