Query: NC_012815:1465670 Bifidobacterium animalis subsp. lactis DSM 10140, complete genome
Lineage: Bifidobacterium animalis; Bifidobacterium; Bifidobacteriaceae; Bifidobacteriales; Actinobacteria; Bacteria
General Information: Bifidobacterium animalis subsp. lactis (strain DSM 10140 / JCM 10602 / LMG 18314) is an anaerobic Gram-positive lactic acid bacterium commonly found in the guts of healthy humans and has been identified in the infant gut biota, particularly in ileal, fecal, and mucosal samples. Some strains of B. animalis subsp. lactis are able to survive in the GIT, to adhere to human epithelial cells in vitro, to modify fecal flora, to modulate the host immune response, or to prevent microbial gastroenteritis and colitis.
Subject: NC_013890:808791 Dehalococcoides sp. GT chromosome, complete genome
Lineage: Dehalococcoides mccartyi; Dehalococcoides; Dehalococcoidaceae; Dehalococcoidales; Chloroflexi; Bacteria
General Information: Temp: Mesophile; Habitat: Fresh water, Groundwater. Dehalococcoides sp. GT was isolated from an chloroethene-contaminated aquifer. This strain can dechlorinate trichloroethene and vinyl chloride. This organism was isolated from environments contaminated with organic chlorinated chemicals such as tetrachloroethene (PCE) and trichloroethane (TCE), common contaminants in the anaerobic subsurface. There are at least 15 organisms from different metabolic groups, halorespirators, acetogens, methanogens and facultative anaerobes, that are able to metabolize PCE. Some of these organisms couple dehalogenation to energy conservation and utilize PCE as the only source of energy while others dehalogenate tetrachloroethene fortuitously. This non-methanogenic, non-acetogenic culture is able to grow with hydrogen as the electron donor, indicating that hydrogen/PCE serves as an electron donor/acceptor for energy conservation and growth. This organism can only grow anaerobically in the presence of hydrogen as an electron donor and chlorinated compounds as electron acceptors. Dehalococcoides ethenogenes is typically found at sites contaminated with chlorinated solvents, and have been independently isolated in dozens of sites across the USA.
