Abstract

The present study was carried out to check and assess the enzymatic potential and decomposition capacity of paddy straw by the fungal consortium in-vitro. Burning of paddy straw is observed a big problem in Haryana, which is responsible for air pollution in Haryana and NCR regions. The fungal communities play a dominant role in paddy straw decomposition due to their lignocellulolytic potential and can adapt to adverse conditions of the soil ecosystem. Soil is known to be the excellent habitat for fungi. The lignocellulolytic enzyme helps in the formation of humus and thus increases health and fertility of the soil. Total five fungal forms were isolated from the decomposed paddy straw and identified. These five fungi belong to Deutromycotina (Aspergillus fumigatus, Aspergillus terreus and Fusarium ssp.) and Zygomycotina (Mucor and Rhizopus). In-vitro testing of fungi was done to produce extracellular enzymes, viz. cellulose, pectinase and laccase. The findings suggest the possible ways of utilizing the fungal consortium contributing to the green India revolution and making the country pollution free.
