Query: NC_007086:1224867 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_004757:427483 Nitrosomonas europaea ATCC 19718, complete genome
Lineage: Nitrosomonas europaea; Nitrosomonas; Nitrosomonadaceae; Nitrosomonadales; Proteobacteria; Bacteria
General Information: Ammonia-oxidizing bacterium. This organism is an obligate chemo-lithoautotroph as it only uses ammonia and carbon dioxide and mineral salts for growth, and is an important part of the global biogeochemical nitrogen cycle. It can derive all energy requirements from the oxidation of ammonia to nitrate, driving global nitrogen from the reduced insoluble form to the oxidized and potentially gaseous form (including NO and NO2 which are greenhouse gases). The energy derived from ammonia oxidation is in turn used to drive carbon fixation. This bacterium also provides plants with a readily available form of nitrogen, is important in wastewater treatment, and may be involved in bioremediation of sites contaminated with toxic compounds.
