To examine whether PRP, which is a oil spill response product, extensively enhances the biodegradation of crude oil, the bench-scale batch culture test was carried out. Although the initial rate of the crude oil degradation of PRP added sample was increased with a increase of incubation temperature, it was lower than that of control sample. This result was due to the volatilization of low molecular weight components in crude oil, and was confirmed using the headspace gas analysis. Because the PRP interacted with the crude oil to form a PRP/crude oil mixture that was semisolid and relatively stable, volatile hydrocarbons were trapped and the crude oil degradation was hindered by limited oxygen in aggregate during the experiment. After 5 weeks of incubation at 5, 10, 15 and 20°C, the removal rates of the crude oil(1 g/L) in sample were 35, 40, 55 and 80%, respectively. The CO2 produced from the mineralization of crude oil was measured using the Biometer flask method during 2 months. The addition of PRP did not have any enhancing effect on the evolution CO₂ in the crude oil degradation, but it increased the mineralization in the diesel oil degradation. It can be concluded that PRP could not accelerate the degradation rate of crude oil significantly, but it has a high oil-adsorbing capacity.
