| Abstract | ||
| Two fungal species, Bipolaris hawaiiensis and Emericella nidulans were isolated from soils contaminated by refined oil, were chosen to detect their ability to decompose samples of crude oil, which analyzed by Gas Chromatography/Mass Spectrometry (GC/MS) instruments, on the solid media based on fungi growth rate (FGR) in the medium. The oil samples were selected from the moderate and light oil, which have 27.5 and 36.7 API respectively. It was clearly that both Bipolaris hawaiiensis and Emericella nidulans have the ability to decompose oil, but this ability differs. It is worth to mention that the selected isolates of species were took gradually away from the refined oil pollutant center. As a result, to the growth media, the Bipolaris hawaiiensis recorded the highest growth rate for the two crude oil types. The value of the FGR reached 6.0 cm and 7.0 cm for the Moderate and Light oil respectively. While Emericella nidulans have 5.5 and 4.8 cm to the Moderate and Light oil respectively. This study shows the possibility of taking advantage of these fungi types, Bipolaris hawaiiensis and Emericella nidulans in bioremediation and decomposition of hydrocarbon pollutant | ||
