The Biodegradation of Fuels in Soils and Sediments: Differences as a Function of Mineralogy.
Abstract
Experiments were carried out to determine the effects of substrate mineralogy on the biodegradability of fuel components. Samples of quartz sand (Fischer Sea Sand) and illite clay (API#35) were spiked wilt DFM, aged, slurried and inoculated with DFM-acclimated soil microorganisms. Then, the concentrations of fuel components were monitored over time. While there was clear chromatographic and biomarker evidence of TPH biodegradation on the sands, illite samples showed no evidence of biogenic loss of aliphatic components. PAHs, on the other band, degraded equally well on both substrates, and in both cases, degraded to a much greater extent than did TPH.
