Abstract

Biodegrading capability of fungi isolated from oil-contaminated soil in three auto-mechanic workshops in Minna, Nigeria was determined by mycelial extension rate measurement method. Penicillium strain 8 I 0 IF, 8201 F and B202F and Mortierel/a strain B I 002F were identified as best crude oil (lagoma light) degraders compared to the other isolates such Aspergillus strain BI02F, BI04F and Bll9F, Fusarium strain 8501F and Trichoderma strain K602F and K561F. The optimum pH and temperature forB I 0 IF and B l 002F to degrade crude oil were 5.0 and 28 •c respectively. When complex nutrient such as maize bran was used as nitrogen source with crude oil in minimal salt liquid medium (MSLM) omitting NaN03, the optimum growth reached on 14tl' day of fermentation for both the isolates. BIOIF and BI002F were capable of using crude oil as both carbon and energy source in minimal salt medium. In view of their ability to utilize crude oil as carbon and nitrogen source, these organisms may be used in mitigating the pollution arising out of oil spills in the environment
