Abstract—Polycyclic aromatic hydrocarbons-contaminated
soil and sewage sludge mixtures in microcosms were tested
separately in triplicate with two types of biological agents,
namely earthworms (Lumbricus rubellus) and spent fungal
mycelia of Pleurotus sajor-caju (SPC) for 60 days. The results
indicated that vermiremediation (VMR) and mycoremediation
(MYC) showed degradation result of 99.99% PAHs i.e. Anth,
Phen and BaP removal. Ten earthworms and 750 g of SPC
depicted optimum results in nutrient element content among
respective treatments. Treatment of MYC resulted a
consistence increment of soil macronutrients except for TP and
TKN (500 g treatment) compared to VMR. Hence, sixty days
incubation of spent fungal mycelia of Pleurotus sajor-caju
compost (SPC) is potential to degrade 99.99% of Anth, Phen
and BaP but at the same time enrich the soil macronutrients i.e.
TOC, TKN and TK.
Index Terms—Bioremediation, lumbricus rubellus, spent mushroom compost, vermitechnology.
