Query: NC_007086:1936505 Xanthomonas campestris pv. campestris str. 8004, complete genome
Lineage: Xanthomonas campestris; Xanthomonas; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: The original was isolated from an inflected cauliflower in Sussex, United Kingdom, in 1958. Strain 8004 is a spontaneous rifampicin resistant strain. Causes black rot disease in crucifers. These organisms are almost exclusively found associated with their plant hosts and are not found free in the soil. This species is a major cause of black rot in crucifers, a disease that results in massive tissue degeneration. It also produces an extracellular polysaccharide known as xanthan, which is harvested commercially as a food stabilizing agent for use in industry.
Subject: NC_009138:2242470 Herminiimonas arsenicoxydans, complete genome
Lineage: Herminiimonas arsenicoxydans; Herminiimonas; Oxalobacteraceae; Burkholderiales; Proteobacteria; Bacteria
General Information: Herminiimonas arsenicoxydans was isolated from heavy metal contaminated sludge from an industrial water treatment plant. This organism has a number of mechanisms for metabolizing arsenic allowing it to effectively colonize arsenic-contaminated environments. A bacterium capable of oxidizing and reducing arsenic. This heterotrophic bacterium is capable of reducing and oxidizing arsenic with the objective of detoxification. Arsenic is both a product from natural sources and of human activities, and is widely distributed in the environment, essentially in 3 different oxidation states: As (-III) (arsine), As (+III) (arsenite) and As (+V) (arseniate). The ecology of this metalloid is strongly dependent on microbial transformations which affect the mobility and bioavailability as well as the toxicity of arsenic in the environment.
