Abstract: | "This work systematically compared the potential of a conventional fungal biofilter (BF) and a fungal biotrickling filter (BTF) for the abatement of a mixture of hydrophobic volatile organic compounds (VOCs). Candida subhashii was herein used for the first time, to the best of the author's knowledge, to remove n-hexane, trichloroethylene, toluene and alpha-pinene under aerobic conditions. C. subhashii immobilized on polyurethane foam supported steady state removal efficiencies of n-hexane, trichloroethylene, toluene and alpha-pinene of 25.4 +/- 0.9%, 20.5 +/- 1.0%, 19.6 +/- 1.5% and 25.6 +/- 2.8% in the BF, and 35.7 +/- 0.9%, 24.0 +/- 1.6%, 44.0 +/- 1.7% and 26.2 +/- 1.8% in the BTF, respectively, at relatively short gas residence times (30 s). The ability of C. subhashii to biodegrade n-hexane, TCE, toluene and alpha-pinene was confirmed in a batch test conducted in serum bottles, where a biodegradation pattern (toluene approximately n-hexane > alpha-pinene > trichloroethylene) comparable to that recorded in the BF and BTF was recorded" |
