Investigation of Fungal Degradation Efficiency on Spent Engine Oil
Abstract
The contamination of soil by spent engine oil is on the increase due to increased use of engines that use petroleum products. This study was aimed to investigate the biodegradation of spent engine oil using indigenous fungi isolated from soil samples. Engine oil contaminated soil was collected from two mechanic workshops located around Alex Ekwueme Federal University Ndufu-Alike. From the collected samples indigenous fungi were isolated using Sabouraud Dextrose Agar. A total of thirty isolates (100%) were isolated among which Aspergillus sp (60%) and Penicillium sp (30%) were found to be predominant. Morphological studies of the fungal isolates showed different growth patterns. Screening of the isolates for biodegradation potential was done using the Minimal Salt Medium, where six (20%) of the fungal isolates that passed the screening test were used. Biodegradation study was conducted for 15 days, isolates of Aspergillus CA4(2), Penicillium CB3(1), and Penicillium CA2(2) had a percentage rate of degradation of 78.9%, 72.1% and 65.9% respectively, while the isolate of Aspergillus CB3(3) recorded the least at 34.9%. The GC-MS result showed loss of hydrocarbons compound from the residual degraded oil and a 100% removal of pentadecane. The result revealed that the fungal isolates indigenous to contaminated engine oil sites have the potential to breakdown hydrocarbons, which makes them potent organisms for environmental cleanup.
