Pyrene Biodegradatin in Aqueous Solutions and Soil Slurries By< I> Mycobacterium Pyr-1 and Enriched Consortium
To better understand complex bioavailability issues, pyrene degradation was examined in aqueous and soil slurry solutions using pure Mycobacterium sp. PYR-1 and a microbial consortium. The intrinsic rates of the aqueous pyrene degradation were very similar, pyrene/CFU-h for Mycobacterium sp. PYR-1 and pyrene/CFU-h for the consortium. Rates were much lower with the soil-slurry experiments, ranging from 1.2×10−12 to , depicting the strong negative effects of soils on bioavailability. Supernatants from the slurry experiments were found to increase the aqueous-phase pyrene solubility significantly. Pyrene solubility was increased from 120.5 to over . However, the linear adsorption constants of pyrene on the soil were reduced.
