摘要：The research on utilization of spent mushroom substrate (SMS), vermicompost (VC), domestic compost (DC) and leachate (L) as inoculum of microorganisms in bioremediation of 30% oil sludge was conducted. The aim of this study was to obtain the most suitable inoculum in bioremediation of oil sludge. TPH and C/N ratios were analyzed on 15 days of interval, while Polycyclic Aromatic Hydrocarbon (PAH) and heavy metals were measured at the beginning (H-0) and the end of experiment (H-45) for 45 days of experiment. The additional parameters such as acidity (pH), temperature (°C), and humidity of medium (%) were measured. The results showed that all inoculums (SMS, VC, DC and L) affect the diminution of TPH as much as 27.7%, 20.9%, 24.8% and 24.20%, respectively. On the other hand, SMS and VC were able to decrease C/N ratio as much as 18% and 4%, respectively. By contrast, DC and L increased C/N ratio as much as 33% and 1.14%, respectively. In this study, inoculum of SMS and L were able to decrease Cr content (16% and 5.88%, respectively). However, Hg content diminished (29%) only in oil sludge medium with SMS inoculum. The PAH compound can be degraded by all types of inoculum with carbon chain ranged from C6-C54 into shorter carbon chain (C6-C30).
