Lineage: Actinobacillus succinogenes; Actinobacillus; Pasteurellaceae; Pasteurellales; Proteobacteria; Bacteria
General Information: Succinate-producing bacterium. Originally isolated from bovine rumen, this species is one of the most promising succinate producers known. It can utilize a variety of sugars and produce a very high volume of succinate, which is used by the pharmaceutical industry. This organism has been improved over time by growth on fermentable carbon and sodium monofluoroacetate and selection of fluoroacetate-resistant mutants which have a higher succinate yield. The succinate yield has also been improved via a metabolic engineering approach, by cloning and overproducing the PEP-carboxykinase gene which catalyzes the addition of carbon dioxide to PEP to form oxalacetate and can work physiologically in both directions
Subject: NC_006814:1618588 Lactobacillus acidophilus NCFM, complete genome
Lineage: Lactobacillus acidophilus; Lactobacillus; Lactobacillaceae; Lactobacillales; Firmicutes; Bacteria
General Information: This organism is a normal inhabitant of the human intestinal tract. This strain was isolated from a human in 1970. 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. This organism has been studied for its ability to help the human gut maintain its natural microbial community. Strains of this organism are also used in the production of yogurt, cheese and other fermented foods.
