Biodegradation of Gasoil by Fungal Isolates from Petroleum Contaminated Soils

Abstract

Biodegradation of gasoil can be improved using various fungi isolated (Aspergillus sp . and  Alternari sp)  from chronically diesel-oil-polluted soil . Samples were collected from power generators locations in Ramadi city. In this present investigation, bioremediation was carried out through  growth of individual fungicide strains on gasoil and examined for its ability to degrade gasoil hydrocarbon at 26C⁰ was accomplished and assessed by using Gas Chromatography (GC). Evaluated of biodegradable  observed the short-chain alkanes  C₉H₂₀ greater extent than that for the long-chain C₂₁H₄₄. In addition, from the biodegradation efficiencies obtained, it can be inferred that gasoil was amenable to Bioremediation. Results pointed that bioremediation depends on the kind of used fungus such as Alternaria sp. Strain  which are more effective in the degrade of gasoil than the Aspergillus sp Fungi strain
