A novel anthracene-degrading Gram-positive actinomycete, Microbacterium sp. strain SL10 was isolated from a hydrocarbon-contaminated soil at a mechanical engineering workshop in Lagos, Nigeria. The polluted soil had an unusually high total hydrocarbon content of 157 g/kg and presence of various heavy metals. The isolate tolerated salt concentration of more than 4 %. It resisted cefotaxime, streptomycin and ciprofloxacin, but susceptible to meropenem, linezolid and vancomycin. The isolate exhibited growth rate and doubling time of 0.82 days(-1) and 0.84 days, respectively on anthracene. It degraded 57.5 and 90.12 % of anthracene within 12 and 21 days, respectively while the rate of anthracene utilization by the isolate was 4.79 mg l(-1) d(-1). To the best of our knowledge, this is the first report of isolation and characterization of anthracene-degrading Microbacterium sp.
