Solid state fermentation of paddy straw was carried out with non-toxic fungi Phanerochaete chrysosporium (MTCC 787) with different treatments. Phanerochaete chrysosporium MTCC 787was found to posses high endo-?-D-1, 4-glucanase (0.561 and 1.82 IUml-1), exo-1, 4-?-glucanase (0.917 and 2.20IUml-1) and xylanase (0.917Uml-1 and 2.20Uml-1) activity, but low laccase (0.245 and 0.431Uml-1) activity on 15th and 30th day of fermentation respectively. Phanerochaete chrysosporium (MTCC 787) was selected for paddy straw composting under field conditions with different treatments for 60 days. Treatment 5 (Paddy straw + Farm yard manure + Fungal culture (Phanerochaete chrysosporium MTCC 787) + Urea + Rock phosphate) was observed as the best treatment, as it favoured the efficient composting of paddy straw by degrading maximum hemicellulose (48%), cellulose (39.2%), lignin (38%), silica content (35%), total solids (54%) and volatile solids (13.3%). Scanning electron microscopy revealed that, untreated paddy straw exhibited a rigid and highly compact structure, whereas paddy straw treated with T5 (Paddy straw + Farmyard manure + Fungal culture + Urea + Rock phosphate) showed opening of the holo-cellulose fibrils due to creation of pores of different sizes.
