PRETREATMENT OF LIGNOCELLULOSIC WASTES WITH WHITE ROT FUNGI, FOMES LIVID US, THELEPHORA SP. AND TRAMETES VERSICOLOR FOR VERMICOMPOSTINGK. SELVAMI K. SWAMINATHAN, K. RASAPPAN , R. RAJENDRAN AND S. PATTABI
The lignocellulosic waste biomass, vegetable waste, agricultural waste and agro-industrial waste were pretreated with the white rot fungi, Fontes lividus, Thelephora sp. and Trametes versicolor for composting with earthworm aiming that the fungi will degrade the complex plant polymers, lignin, cellulose and hemicellulose by their enzymes thereby accessing simple compounds for earthworm composting. Five types of treatments were tried. In tretment I, the wastes were allowed for natural degradation and it served as control, in treatment II, the fungus alone was inoculated on the substrate, in treatment III, the earthworm, Eudrilus eugeniae alone was inoculated, in the treatment IV, the fungus and the earthworm were inoculated on the same time and in treatment V. the earthworm was inoculated after one month of fungal inoculation. The compost formed was analysed for organic carbon, nitrogen, phosphorus and potassium contents and the C/N ratio was calculated. The effect of application of compost on soil fertility was analysed.It was observed that treatment V was more efficient in composting the waste biomass; the compost obtained in this treatment enhanced the soil fertility than the composts from other treatments.
