Query: NC_007760:1806136 Anaeromyxobacter dehalogenans 2CP-C, complete genome
Lineage: Anaeromyxobacter dehalogenans; Anaeromyxobacter; Myxococcaceae; Myxococcales; Proteobacteria; Bacteria
General Information: This strain differs from other isolates based on the combination of its ability to use 2,5-dichlorophenol and its inability to use nitrate as a strong electron acceptor. It can also dechlorinate 2,4-dichlorophenol and 2,4,6-trichlorophenol much faster than other isolates. Can dehalogenate chlorinated phenols. This anaerobic species was originally isolated by enrichment and isolation of single plate-grown colonies, and was the first pure culture of myxobacteria able to grow anaerobically.
Subject: NC_010556:141374 Exiguobacterium sibiricum 255-15, complete genome
Lineage: Exiguobacterium sibiricum; Exiguobacterium; Bacillales Family XII; Bacillales; Firmicutes; Bacteria
General Information: This organism was isolated from a 2-3 million-year permafrost core in Siberia, Russia and can survive and grow rapidly at low temperatures. Analysis of long-term survival of psychrophilic organisms such as this one may aid understanding of the potential growth of organisms in astrobiology. Exiguobacterium sibiricum is a psychrotolerant organism able to grow at temperatures that range from -6 to 40 degrees C. This organism is also able to survive repeated freeze/thaw cycles which may contribute to its ability to survive in cold environments.
