Query: NC_009012:3421000 Clostridium thermocellum ATCC 27405, complete genome
Lineage: Clostridium thermocellum; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria
General Information: This strain is a well studied producer of endoglucanase and several restriction endonucleases. Thermophilic cellulose degrading bacterium. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA. Some species are capable of producing organic solvents (acetone, ethanol, etc,), molecular hydrogen and other useful compounds. This organism is a thermophilic anaerobe that produces an extracellular enzyme system capable of degrading crystalline cellulose to soluble sugars that are further utilized as the carbon source for growth.
Subject: NC_007929:1805000 Lactobacillus salivarius subsp. salivarius UCC118, complete genome
Lineage: Lactobacillus salivarius; Lactobacillus; Lactobacillaceae; Lactobacillales; Firmicutes; Bacteria
General Information: Lactobacillus salivarius salivarius strain UCC118 was isolated from the human gastrointestinal tract. This organism produces bacteriocins, antibiotic compounds which have inhibitory effects on pathogenic microorganisms. Lactobacillus salivarius subsp. salivarius strain UCC118 has been extensively studied for its effectiveness as a probiotic to maintain the balance of the gut microbial flora and stimulate the intestinal immune system. Oral and gastrointestinal tract 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 salivarius was first isolated as part of a survey of human oral lactobacilli and is commonly found in the oral cavity and gastrointestinal tract of humans and other animals.
