Query: NC_007912:1173752 Saccharophagus degradans 2-40, complete genome
Lineage: Saccharophagus degradans; Saccharophagus; Alteromonadaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: This strain is a marine gamma-proteobacterium that was isolated from decaying Spartina alterniflora, a salt marsh cord grass, in the Chesapeake Bay, USA. Saccharophagus degradans 2-40 has been used to produce ethanol from plant material and may be useful for the production bioethanol. Bacterium able to degrade complex carbohydrates. Saccharophagus degradans is capable of degrading insoluble complex carbohydrates through the collective action of enzyme complexes found on its cell surfaces, utilizing the degradation products as a carbon source. This organism may be useful in bioremediation. The degradative enzymes this organism produces are typically exoenzymes that are collected and organized into large surface complexes termed cellulosomes.
Subject: NC_002973:72328 Listeria monocytogenes str. 4b F2365, complete genome
Lineage: Listeria monocytogenes; Listeria; Listeriaceae; Bacillales; Firmicutes; Bacteria
General Information: This strain was isolated in 1985 in California, USA, during an outbreak of listeriosis among patients with AIDS. The strain is of serotype 4b and was isolated from a cheese product that caused the outbreak. This organism, which causes listeriosis, is one of the leading causes of death from food-borne pathogens especially in pregnant women, newborns, the elderly, and immunocompromised individuals. It is found in environments such as decaying vegetable matter, sewage, water, and soil, and it can survive extremes of both temperatures (1-45 degrees C) and salt concentration marking it as an extremely dangerous food-born pathogen, especially on food that is not reheated. This organism is enteroinvasive, and utilizes an actin-based motility system by using a surface protein, ActA, that promotes actin polymerization, to spread intercellularly using the polymerized cytoskeletal protein as a "motor". There are 13 serovars associated with Listeria monocytogenes, and the serovar 4b strains are more commonly associated with invasive disease.
