ABSTRACT
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 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 d. To the best of our knowledge, this is the first report of isolation and characterization of anthracene-degrading Microbacterium sp.
