Rhodococci are aerobic, Gram positive actinomycetes of high G+C content, capable of morphological differentiation in response to their environment (e.g., cocci or filaments). These widely occurring organisms are of considerable environmental and biotechnological importance due to their broad metabolic diversity and array of unique enzymatic capabilities. These are of interest to the pharmaceutical, environmental, chemical and energy sectors. Specific applications include the desulphurization of fossil fuels and the industrial production of acrylamide. Rhodococci are well suited for bioremediation due to their capacity for long term survival in soil, their exceptional ability to degrade hydrophobic pollutants even in the presence of more readily assimilable carbon sources, and their ability to accumulate high levels of heavy metals.

Rhodococcus erythropolis PR4 (NBRC 100887) was isolated from the Pacific Ocean, south of Okinawa Island, Japan, at a depth of 1,000 m. This strain can degrade various alkanes (C8-C20 n-alkanes, branched alkanes including pristane) and methylbenzenes (such as toluene), but not benzene or naphthalene, as sources of carbon and energy. It produces a large quantity of extracellular polysaccarides (EPSs), which are assumed to play an important role in the tolerance to a variety of organic solvents. The genome consisted of one circular chromosome, one linear plasmid, and two circular plasmids. Genes for the degradation of alkanes were found on the chromosome and plasmids. Genes for the degradation of intermediates of the aromatic hydrocarbon catabolism, such as protocatechuic acid and catechol, were clustered on the chromosome. The genome also contains a number of secondary metabolism genes and EPS biosynthesis genes (modified from
