Abstract
The efficiency and kinetics of naphthalene biodegradation in a soil medium using Pleurotus ostreatus (a type of white rot fungus) in batch mode with and without the addition of oil palm fiber (OPF) as a nutrient are evaluated in this study. Three batches are considered in the biodegradation study: (i) control—spiked soil; (ii) spiked soil with fungus; and (iii) spiked soil with both fungus and OPF. Biodegradation is conducted over a period of 22 days for which soil naphthalene concentrations are determined with respect to microwave extraction and high-performance liquid chromatography (HPLC) analysis. The results indicate that inoculation with Pleurotus ostreatus significantly enhances soil naphthalene biodegradation to 84%, which is further enhanced upon the addition of OPF to 98% with respect to the degradation rate. The high carbon content in OPF (>40%) affords it the capacity to be a viable nutrient supplement for Pleurotus ostreatus, thereby enhancing the potential of Pleurotus ostreatus in the biodegradation of polycylic aromatic hydrocarbons (PAHs), and indicating the potential of OPF as a nutrient for PAH biodegradation. A relationship between OPF mass and the biodegradation rate constant has been determined to be linear according to the following equation: k = 0.0429 × OPF + 0.1291.
