چکیده انگلیسی
The capacity of Phanerochaete chrysosporium grown on soil with added sugarcane baggase (BP) and pine sawdust (PS) to remove benzo(a)pyrene (BaP) was studied. A half factorial two-level experiment 24-1 was designed to determine the effect of: type of lignocellulosic material (BP and PS) for fungus growth, age of fungus (5 and 10 d), amount of lignocellulosic material (10% and 15% w/w) and soil moisture content (water holding capacity of 45% and 56% w/w). Inoculum obtained at different ages showed that the capacity of P. chrysosporium to remove BaP depends on the lignocellulosic used and on inoculum age. Abiotic BaP removal was affected significantly (p < 0.05) by inoculum age, type of lignocellulosic added and soil moisture content. The removal of BaP by lignocellulosic material was more effective by young inocula (71.97 mg BaP kgâ1 dry soil), with high percentage of added lignocellulosic (71.57 mg BaP kgâ1 dry soil) and at low soil moisture content (73.07 mg BaP kgâ1 dry soil). When fungus was grown on BP, maximum BaP removal rate was obtained at 5 d of incubation (10.85 mg BaP dâ1 lâ1 and 50.12 mg BaP kgâ1 dry soil), while in PS maximum BaP removal was obtained at 10 d of incubation (12.06 mg BaP dâ1 lâ1 and 39.94 mg BaP kgâ1 dry soil).
