General Information: This strain is isolated from traditional dairy products of minority nationalities in China. The subspecies bulgaricus is used as a starter culture for a number of fermented dairy products such as yogurt and Swiss and Italian-type cheeses, and is a thermophilic culture, where the optimum temperature is 42 C.
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.
