Query: NC_018532:166468 Arthrobacter sp. Rue61a plasmid p232, complete sequence
Lineage: Arthrobacter; Arthrobacter; Micrococcaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Bacteria of the genus Arthrobacter are ubiquitous in the environment. They are characterized by nutritional versatility and pronounced resistance to desiccation, long-term starvation, toxic compounds, oxidative stress, and other environmental stress conditions. Arthrobacter nitroguajacolicus strain Rü61a was previously isolated from sludge of the biological wastewater treatment plant of a coal tar refining company, based on its ability to utilize quinaldine (2-methylquinoline) as source of carbon and energy.
Subject: NC_008146:2744612 Mycobacterium sp. MCS, complete genome
Lineage: Mycobacterium; Mycobacterium; Mycobacteriaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Mycobacterium MCS was isolated from soil in a wood preservative-contaminated land-treatment unit where remediation of polycyclic aromatic hydrocarbon (PAH) was occurring. This isolate mineralizes small- and large-ring PAHs, in contrast to other PAH-degrading microbes. Bioremediation of PAHs offers an attractive solution to pollution clean-up because it can occur on site and at relative little cost compared to alternatives. This isolate belongs to a fast-growing group of the mycobacterium genus that is defined as Gram-positive, acid-fast, pleomorphic, non-motile rods. Bioremediation of soils contaminated with wood preservatives containing polycyclic aromatic hydrocarbons (PAHs) is desired because of their toxic, mutagenic, and carcinogenic properties. Creosote wood preservative–contaminated soils at the Champion International Superfund Site in Libby, Montana currently undergo bioremediation in a prepared-bed land treatment unit (LTU) process.
