Query: NC_009342:2528426 Corynebacterium glutamicum R chromosome, complete genome
Lineage: Corynebacterium glutamicum; Corynebacterium; Corynebacteriaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: This strain was isolated from meadow soil in Japan. Soil bacterium with industrial uses. 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 well-studied soil bacterium of considerable importance in biotechnology, in particular for the fermentative production of L-amino acids for food and fodder industry. The name was originaly given for this species for its ability to produce significant quantities (>100 g per liter) of glutamic acid (glutamate), an important food enhancer that has a meaty taste and flavor. C. glutamicum is currently used commercially to produce glutamate and other amino acids (L-lysine) and compounds. The first strain of the species was isolated in 1957 by S. Kinoshita and colleagues while searching for an efficient glutamate-producer.
Subject: NC_008530:1551356 Lactobacillus gasseri ATCC 33323, complete genome
Lineage: Lactobacillus gasseri; Lactobacillus; Lactobacillaceae; Lactobacillales; Firmicutes; Bacteria
General Information: Lactobacillus gasseri ATCC 33323 is a human isolate and is the type strain. This organism has been shown to have probiotic activities such as production of bacteriocins, macrophage stimulation and adherence to intestinal tissues. Normal gastrointestinal bacterium. They are commonly found in the oral, vaginal, and intestinal regions of many animals. They are important industrial microbes that contribute to the production of cheese, yogurt, and other products such as fermented milks, all stemming from the production of lactic acid, which inhibits the growth of other organisms as well as lowering the pH of the food product. Industrial production requires the use of starter cultures, which are carefully cultivated, created, and maintained, which produce specific end products during fermentation that impart flavor to the final product, as well as contributing important metabolic reactions, such as the breakdown of milk proteins during cheese production. The end product of fermentation, lactic acid, is also being used as a starter molecule for complex organic molecule syntheses. Lactobacillus gasseri is a rod-shaped, gram-positive anaerobe. Of the lactobacilli, it is the most amenable to DNA introduction and manipulation which should prove useful in the functional genomic analysis of this species. It has been shown to be an effective probiotic in suppressing Helicobacter pylori infections in humans.
