Query: NC_012668:1036000 Vibrio cholerae MJ-1236 chromosome 1, complete sequence Lineage: Vibrio cholerae; Vibrio; Vibrionaceae; Vibrionales; Proteobacteria; Bacteria General Information: Vibrio cholerae MJ-1236 is a toxigenic O1 El Tor Inaba strain from Matlab, Bangladesh, 1994 that represents the "Matlab variant" of El Tor. This genus is abundant in marine or freshwater environments such as estuaries, brackish ponds, or coastal areas; regions that provide an important reservoir for the organism in between outbreaks of the disease. Vibrio can affect shellfish, finfish, and other marine animals and a number of species are pathogenic for humans. Vibrio cholerae can colonize the mucosal surface of the small intestines of humans where it will cause cholera, a severe and sudden onset diarrheal disease. One famous outbreak was traced to a contaminated well in London in 1854 by John Snow, and epidemics, which can occur with extreme rapidity, are often associated with conditions of poor sanitation. The disease has a high lethality if left untreated, and millions have died over the centuries. There have been seven major pandemics between 1817 and today. Six were attributed to the classical biotype, while the 7th, which started in 1961, is associated with the El Tor biotype.

General Information: Rhodococcus erythropolis PR4 (NBRC 100887) was isolated from Pacific Ocean seawater. It has the enzymes necessary for the degradation of different alkanes, such as pristane. PR4 shows tolerance to hydrocarbons and it is capable of producing several compounds with medical, industrial, and nutritional applications such as beta-carotenes (i.e. astaxanthin) and fatty acid-containing extracellular polysaccharides (i.e. mucoidan). Rhodococcus species are soil bacteria with remarkable metabolic versatility leading to several possible applications in the pharmaceutical and chemical industries and for industrial bioremediation. This species has shown potential in producing different valuable compounds. As examples, some Rhodococcus erythropolis strains posses a nitrile hydratase, an enzyme used for the industrial production of acrylamide and nicotinamide, while other strains are capable of transforming indene to 1,2-indandiol, a key precursor of the AIDS drug Crixivan.
