ABSTRACT

Three hundred five samples of partially decomposed paddy crop residues were collected from Dhamtari, Kanker, Bastar, Durg, Raipur and Mahasamund districts of Chhattisgarh plains in order to isolate and identify effective lingo-cellulolytic fungal isolates for quick recycling of paddy crop residues. In this connection, 110 fungal isolates were isolated. These isolates were mostly belonging to fungal genera Aspergillus, Trichoderma, Penicillium, Mucor etc. All the isolates were further tested for lignin and cellulose decomposing ability. Out of the total 110 isolates, 25 fungal isolates showed lignolysis. While 63 isolates showed cellulose degrading ability

Keywords : Ligno-cellulolytic fungal isolates, paddy crop residues, paddy stubbles and Chhattisgarh plains.
