摘要

This study was conducted to investigate the degree of bioremediation that would occur in the samples of soil polluted with raw and treated crude petroleum (oil) with the aid of Aspergillus niger (fungi) and Pseudomonas aeruginosa (bacteria). This was achieved by monitoring the Organic carbon content in the soil over 45 days and pH over 25 days. Four systems of 500 g soil were polluted with 40 g treated crude petroleum, while four systems were contaminated with 40 g raw crude petroleum. The eight systems were labeled accordingly. Two systems for raw crude control and treated crude control (RCC and TCC) were left as control, two systems for raw crude Aspergillus niger and treated crude Aspergillus niger (RCA and TCA) were treated with Aspergillus niger only, two systems for raw crude Pseudomonas aeruginosa and treated crude Pseudomonas aeruginosa (RCP and TCP) were treated with Pseudomonas aeruginosa only and the last two systems for raw crude Aspergillus niger and Pseudomonas aeruginosa (RCAP and TCAP) were treated with both Pseudomonas aeruginosa and Aspergillus niger . At the end of the bioremediation period, the results obtained showed that the pH was not particularly a solid parameter to estimate the degree of bioremediation. This is because a proper trend in the results obtained could not be determined. Additionally, it was observed that Aspergillus niger (fungi) and Pseudomonas aeruginosa (bacteria) alone and separate remediate raw crude polluted soil better than treated crude polluted soil. This was determined by the TOC (Total Organic Carbon) values on the 45th day of the experiment.
