Mycoremediation of crude oil contaminated soil by specific fungi isolated from Dhahran in Saudi Arabia.

Crude oil biodegrading microorganism considers the key role for environmental preserving. In this investigation, crude oil biodegrading fungal strains have been isolated in polluted soil of crude-oil at khurais oil ground in Kingdom of Saudi Arabia. Among of 22 fungal isolates, only three isolates reflected potential capability for oil degradation. These isolates were identified and submitted to GenBank as (A1) (MT448790, (A2) (MT448791 and (A3) (MT459302) through internal-transcribed spacer-regions (ITS1&ITS2) for sequencing in molecular marker. Comparing with controls, strain (A1) was superior for biodegradation ability (58%) comparing with and degrading were showed 47 and 51% respectively. Employed CO evolution as indicator for petroleum oil biodegradation by the fungal isolates reflected that, emission highest CO2 (28.6%) comparing with and which showed 13% and 12.4% respectively. capability of  sp. to tolerate and adapted oil pollutants with successful growth rate on them, indicated that it can be employed as mycoremediation agent for recovering restoring ecosystem when contaminated by crude oil.
