Abstract
The results showed that two fungi used in this research had positive and effective role in biodegradation of Kirkuk mid crude oil and Al-Qayarah heavy crude oil. Synergism between F.moniliforme and A.flavus was able to biodegrade hydrocarbons of Kirkuk mid crude oil by percent 86.6% then A.flavus could biodegrade the same crude oil by percent 85.3% where's F.moniliforme at third stage by percent 68.6%. But the percent of biodegradation of Al-Qayarah heavy crude oil, showed that synergim could biodegrade by percent 81.05%. A.flavus by percent 78.9% but F. moniliforme by percent 65.4%. From the results of viable counts for the two grown fungi on the two kinds of crude oil showed adaptation for new ecology and increase in 1st and 2nd weeks from growth but decrease the viable counts for two fungi in the 3rd., 4th. weeks of growth, analysis by gas-chromatography improved biodegradation the hydrocarbons of two kinds of crude oil by the action of two fungi used in this research. These two techniques produced another type for measured the profile oil hydrocarbons and disappeared many of peaks include components of crude oil which cleared through hydrocarbons profile before and after using two fungi as biotic analyzed factors, to affirmative results which cleared by weight as percent's in this research.
