| description | The experiment under lab condition was conducted to investigate the effect of petroleum
hydrocarbon contamination on soil microorganisms and biodegradation. The experiment was
conducted in 12 treatment and three replication. The treatments include soil contaminated with
Kerosene, Diesel, lubricate oil and used lubricate oil in three concentration 0%, 5%, and 10%.
contamination with hydrocarbons significantly decreased the count of heterotrophic bacteria and
there was reversal relationship between the contaminant concentration and the count of
heterotrophic bacteria. The results indicated soil contamination with hydrocarbons significantly
increased the count of Hydrocarbon Utilizing Bacteria (HUB). The effect of petroleum
hydrocarbons on fungi count differed according to the type of hydrocarbons, concentration of
contaminant and the periods of incubation. Our results show that soil contamination by
hydrocarbons caused significant increase in actinomycetes count at all hydrocarbon types and
concentrations except 5% used and non-used lubrication oil. The higher percentage of
biodegradation in hydrocarbons contaminated soil 49.6% was recorded in soil contaminated with
5% kerosene while the lower percentag10.8% was recorded with soil contaminated 10% lubricate
oil. |
