The performance of a lab-scale biotrickling filter inoculated with a mixed fungal consortium was investigated for the simultaneous abatement of 2-ethylhexanol; a hydrophobic semi-volatile organic compound, and propylene glycol monomethyl ether. The biotrickling filter performance was investigated in the presence of lipopeptide-type biosurfactant, surfactin. The effect of surfactin on the removal efficiency and elimination capacity was examined at stretched inlet loading rates: 1.04 to 15.7 and 3.2-48 g m-3 h-1 of propylene glycol monomethyl ether and 2-ethylhexanol, resp. Seeding the biotrickling filter with 50 mg L-1 of surfactin maintained high and consistent removal efficiencies of propylene glycol monomethyl ether and 2-ethylhexanol up to loading rates of 15.7 and 32 g m-3 h-1, with removal efficiencies of 98.5 and 99%, resp. Once the loading rate of 2-ethylhexanol increased to 48 g m-3 h-1, a substrate inhibition was observed, accompanied by a sudden decrease in removal efficiency from 99.2 to 62.3%. At the same loading rates, the biotrickling filter performance was improved by reseeding 100 mg L-1 of surfactin, hence, reinstated the removal efficiency of 2-ethylhexanol to 92.7% and achieving a maximum elimination capacity of 44.5 g m-3 h-1. This enhanced semi-volatile organic compounduptake rate was further confirmed by a considerable increase in reaction rate constant from 0.005 to 0.017 s-1. A batch study was also conducted at the end of the exptl. run to better understand the correlation between surfactin concentrations and the time-dependent partition coefficient of 2-ethylhexanol. Biofilm microbial community structure revealed relative abundancy of 72 and 28% of Trichoderma asperellum and Fusarium solani, resp. The findings of this study show for the first time that the removal of a semi-volatile organic compd such as 2-ethylhexanol is feasible in the presence of surfactin and hence improving the bioavailability of hydrophobic semi-volatile organic compound
