The remediation potentials of diesel oil by two white rot fungi
(Basidiomycota; Hymenomycetes)
Heterobasidion annosum
13.12B and
Resinicium bicolor
were tested in two artificially contaminated experimental matrices: Norkran’s liquid
medium and Insch - Pitcaple soil collected from Aberdeen, United Kingdom. Gravimetric
measurements showed reductions in the weight of the hydrocarbon extract from soil
inoculated with
H. annosum 13.12B and
R. bicolor. The reduction in diesel extract was
observed to be higher in the treatments with
H. annosum 13.12B compare with other
treatments in soil microcosm amended with 3.5 and 7 % diesel oil. Significant increase in
extractable hydrocarbon was detected in Norkran’s liquid medium amended with 1 and 3.5
% diesel oil. These results showed that white rot fungi could be harnessed to remediate soil
contaminated with diesel oil in the field.
