indigenous white rot fungus Lentinus squarrosulus in degrading
engine oil in soil. Flasks containing sterilized garden soil (100 g) moistened
with 75% distilled water (w/v) were contaminated with engine oil 1, 2.5,
5, 10, 20 and 40% w/w concentrations, inoculated with L. squarrosulus
and incubated at room temperature for 90 days. Levels of organic matter,
pH, total hydrocarbon and elemental content (C, Cu, Fe, K, N, Ni, Zn and
available P) were determined post-fungal treatment. Results indicate that
contaminated soils inoculated with L. squarrosulus had increased
organic matter, carbon and available phosphorus, while the nitrogen and
available potassium was reduced. A relatively high percentage degradation
of Total Petroleum Hydrocarbon (TPH) was observed at 1% engine oil concentration
(94.46%), which decreased to 64.05% TPH degradation at 40% engine oil
contaminated soil after 90 days of incubation. The concentrations of Fe,
Cu, Zn and Ni recovered from straw/fungal biomass complex increased with
the increase of engine-oil contamination and bio-accumulation by the white-rot
fungus. The improvement of nutrient content values as well as the bioaccumulation
of heavy metals at all levels of engine oil concentrations tested through
inoculations with L. squarrosulus is of importance for the bioremediation
of engine-oil polluted soils.]]>Adenipekun, C.O. and I.O. Fasidi,2005Lentinus subnudus, a Nigerian white-rot fungus.]]>4796798AOAC,19801980Atagana, H.I., R.J. Haynes and F.W.
