From this viewpoint, fungus has been the relatively less explored group although the fungi possess a huge number of enzymatic activities which can be easily used to replace different chemicals in various industries for lowering down their pollution levels. Fungi have diverse capacities to biotransform and to completely destroy toxic chemicals viz. pesticides/xenobiotics etc. from our environment. Their ligninolytic enzyme complex is reported to be the best for degradation of such pollutants. This enzyme system is also reported to be involved in the degradation of highly recalcitrant lignin biomolecule. Basidiomycete group of fungi especially white rot fungi are reported to be the best microorganisms for lignin degradation due to their unique abili...

Handmade papermaking is an eco-friendly option. However with the increasing demand of handmade paper, this sector is also facing challenges. Calotropis procera is one of the alternative raw materials for making excellent varieties. Owing to its lignocellulosic nature, pulping chemicals are introduced which can be minimized/ eliminated through biopulping with the utilization of white rot fungi. In the present study, white rot fungal isolates identified as Schizophyllum commune and Perenniporia tephropora have been evaluated for degrading lignin of C. procera fibre so that the most efficient isolate may be used further for biopulping to make handmade paper in an eco-friendly manner. Ganoderma lucidum (MTCC-1039) was also studied for comparison. To ascertain the lignin degradation capabilities, the development of zones of clearance was observed on the innovatively designed media plates. Accordingly, efficiency of the tested cultures was found to be in the order: G. lucidum > S. commune > P. tephropora. On proximate analysis of the fungal pre-treated fibre, S .commune reduced klason lignin to a level of 4.34% from the original value of 12.98% without ill-affecting the cellulose contents. Thus, S. commune was identified as an efficient strain for lignin degradation implying its suitability as a biopulping agent in handmade paper industry.
