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-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.
