Query: NC_013943:382807 Denitrovibrio acetiphilus DSM 12809 chromosome, complete genome
Lineage: Denitrovibrio acetiphilus; Denitrovibrio; Deferribacteraceae; Deferribacterales; Deferribacteres; Bacteria
General Information: Isolation: Oil reservoir model column; Country: Norway; Temp: Mesophile; Habitat: Fresh water, Marine. This organism was first isolated from an oil reservoir modeling column under nitrate enrichment and reduces nitrate to ammonia. Stimulating the growth of nitrate-reducing bacterium in an oil well may prevent the growth of sulfate-reducing bacterium which cause reservoir souring by the production of H2S.
Subject: NC_012416:4973 Wolbachia sp. wRi, complete genome
Lineage: Wolbachia; Wolbachia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria
General Information: Endosymbiont. Obligate intracellular bacterium infects around 20% of all insect species. Naturally infects Drosophila simulans and induces almost complete cytoplasmic incompatibility in its host. Wolbachia sp. subsp. Drosophila simulans (strain wRi) is an intracellular proteobacterium that infect insects as well as isopods, spiders, scorpions, mites, and filarial nematodes. It is maternally inherited and induces reproductive alterations of insect populations by male killing, feminization, parthenogenesis, or cytoplasmic incompatibility. In insect populations, Wolbachia sp. induce reproductive manipulations to enhance their own spreading. The most frequently observed reproductive abnormality is cytoplasmic incompatibility, where uninfected females are unable to produce offspring with infected males, whereas infected females can produce offspring with both infected and uninfected males, thus creating a reproductive advantage for infected females. Other spectacular effects of Wolbachia sp. infections are male embryo killing, feminization, and parthenogenesis induction.
