Effects of biological pre-treatment of lignocellulosic waste with white-rot fungi on the stimulation of 14C-phenanthrene catabolism in soils

The enhancement of phenanthrene catabolism in soils amended with lignocellulosic waste material (spent brewery grains) was investigated. were pre-treated five white-rot fungi ( Phanerochaete chrysosporium , Trametes versicolor Irpex lateus Pleurotus ostreatus, and Bjerkandera adusta ). changes the kinetics 14 C-phenanthrene mineralisation (lag phases, fastest rates overall extents) measured inoculated, PAH-amended over time (1–100 d). Changes ligninolytic (laccase, lignin peroxidase manganese peroxidase) non-ligninolytic (β-glucosidase phosphatase) enzymatic activities also assessed. Overall results revealed that amendment fungal SBG influenced as well soils. Soil inoculated caused reductions lag phases higher extents following trend T. > B.

These findings provided an insight on potential biological pre-treatment materials for enhanced carbon, energy nutrients bioactivities biodegradation organic pollutants which may be applicable during situ remediations contaminated soil. • Fungal facilitated soil time. microbial activities. more efficient degraders PAH Phenanthrene decreased activity but enzymes.
