Query: NC_012632:1212780 Sulfolobus islandicus M.16.27 chromosome, complete genome
Lineage: Sulfolobus islandicus; Sulfolobus; Sulfolobaceae; Sulfolobales; Crenarchaeota; Archaea
General Information: This strain was isolated from a hot spring on the Kamchatka Penninsula, in the Russian Far East. Hyperthermophilic acidophilic sulfur-metabolizing archeon. Sulfolobus islandicus is a thermo-acidophilic archeae commonly identified in hot, acidic sulfur springs. This organism can grow both chemoautotrophically, using sulfur or hydrogen sulfide, and heterotrophically. S. islandicus can play host to a number of plasmids and viruses which may be useful in developing tools for genetic analysis. In addition, Sulfolobus islandicus isolates from different areas in Russia, Iceland, and the United States have been shown to be genetically distinct from each other making this organism useful for comparative analysis.
Subject: NC_004369:2968251 Corynebacterium efficiens YS-314, complete genome
Lineage: Corynebacterium efficiens; Corynebacterium; Corynebacteriaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: This is the type strain of C. efficiens isolated by researchers of Ajinomoto food company from soils at Kanagawa, Japan in the late 1980's. The strain can grow and produce glutamate at temperatures above up to 45oC in contrast to C. glutamicum that is only efficient at around 30oC. This feature is very beneficial for industrial applications, because less heat removal is required in fermenters to be used for cultivation of these bacteria. Glutamate-producing bacterium. They may be found as members of the normal microflora of humans, where these bacteria find a suitable niche in virtually every anatomic site. This organism is a recently proposed new species of the genus capable of producing significant quantities of glutamic acid (glutamate), an important enhancer of taste in the food industry. It is currently used commercially to produce glutamate and other amino acids and compounds.
