Biological treatment of oil spill in Iraqi soil
Hussein Al Nasrawi
Southern Technical University, Iraq
The present study was conducted to identify isolation of fungi
from soil polluted with oil spill from southern area of Iraq
.Three species of fungi were isolated from polluted soil, the
fungi belongs to: Aspergillus niger, Fusarium sp. and Penicillium
sp. Only A.niger shows biodegradation ability of crude oil in
liquid medium , in addition to test two white rot fungi Agaricus
bisporus and Pleurotus ostreatus. Results revealed that 80%
of hydrocarbons PAHs was biodegraded by A.niger under 25
cº and 75% in 20 and 30 cº. whereas Agaricus bisporus and
Pleurotus ostreatus biodegraded 55% and 50% PAHs under
25 cº and 20,30 cº respectively. Diameter of A.niger colony
revealed 90mm. Growth in PAmediumenriched with 1% crude
oil. The percentage of PAHs degraded by Agaricus bisporus and
Pleurotus ostreatus was 90% in successionwith A.niger and C/N
ratio decreased from 20.5:1 to 18.5:1 in addition to advance of
