| dc.description | Different kinetic models have been proposed to describe the elimination of hydrophobic volatile organic compounds (VOCs) by fungal biofiltration. In this process the ratio of the initial substrate concentration (C-b0(p)) to the initial biomass (X-0) has been shown to influence the cell yield. This paper presents a study of the effect of the C-b0(p)/X-0 ratio on observed cell yield (Y-obs) in a fixed bed batch system (microcosm) using a gaseous carbon source, as an approximation to its application in the fungal biofiltration of hydrophobic VOCs. Essays were carried out in fixed-bed microcosms using the filamentous fungus Fusarium solani as a biological agent and n-pentane as a carbon and energy source. The results indicated that Y-obs in the gas phase is inversely proportional to the C-b0(p)/X-0 ratio, with values of 0.9 to 0.35 g(biomass) g(pentane)(-1) being obtained when the C-b0(P)/x(0) ratio is changed from 0.1 to 1.0 g(pentane) g(biomass)(-1).The results indicate that more than 60% of n-pentane was consumed due to energy spilling, and that strong dissociation of catabolism from anabolism occurred at higher C-b0(p)/X-0 ratios. | |
