Among all environmental contaminations,
industrial oil is one of the major pollutants of soil, water,
and air. There are different chemical, physical, and biological
methods to remove all types of oil pollutions. One
of the common biological methods is to utilize the
microorganisms like yeast, fungi or bacteria. Previous
studies concerning the biodegradation of an aromatic
compound in industrial waste water by
Aspergillus niger
have been reported. In this study, we tried to identify an
oil-derived microorganism and evaluate its efficacy on selfremoval
of industrial oil. Firstly, the strain of isolated
fungus from various bulks of used oil was defined via
colonial identification and DNA sequencing. Secondly,
bioremoval activity of defined fungus (
Penicillium commune
)
was evaluated using gas chromatography–mass
spectrometry. The optimum conditions in biological elimination
of oil including the incubation time, pH level of
culture, and amount of reagents were determined. In the
best condition, a removal rate of 95.4 % was obtained.
