Biological treatment of oil spill in Iraqi soil

Hussein Al Nasrawi

Southern Technical University, Iraq

T

he 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
