Query: 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.
Subject: NC_011959:972798 Thermomicrobium roseum DSM 5159, complete genome
Lineage: Thermomicrobium roseum; Thermomicrobium; Thermomicrobiaceae; Thermomicrobiales; Chloroflexi; Bacteria
General Information: Thermomicrobium roseum DSM 5159 was isolated from Yellowstone National Park, USA. Obligate thermophile with unusual cell wall structure. Thermomicrobium roseum is a red-pigmented, rod-shaped, Gram-negative extreme thermophile that possesses both an atypical cell wall composition and an unusual cell membrane that is composed entirely of long-chain 1,2-diols. Analyses of environmental sequences from hot spring environments show that T.roseum displays a low quantity but ubiquitous presence in top layers of microbial mats. Few standard housekeeping genes are found on the megaplasmid, however, it does encode a complete system for chemotaxis including both chemosensory components and an entire flagellar apparatus. T. roseum oxidizes CO aerobically, making it the first thermophile known to do so. In addition, is is propose that glycosylation of its carotenoids plays a crucial role in the adaptation of the cell membrane to this bacterium's thermophilic lifestyle. Because T. roseum is a deep-branching member of this phylum, eventhough this species is not photosynthetic, analysis of the genome provides some insight into the origins of photosynthesis in the Chloroflexi.
