ABSTRACT

Wheat straw is an abundant by-product from wheat production. The average yield of wheat straw is 1.3-1.4 lb per lb of wheat grains. Composting is a cost effective and eco-friendly process to dispose abundant agricultural wastes. In our study we apply bacterial and fungal biodegrader consortia to enhance quality of compost. The parameters like pH, moisture, cellulose, lignin, TOC, total nitrogen, C: N ratio and lignocellulolytic enzymatic properties have been analyzed. The C: N ratio at 90 days was 15.02% with mixing of bacterial consortium and 17.04% with treatment receiving fungal consortium as compared to natural composting which were 25.30%. Endocellulase activity increases up to 60 days that was 93.10 IU/g in treatment receiving bacterial consortium while in other lignin peroxidase and laccase was detected in very less amount. The data suggested that bacterial and fungal mixture can degrade wheat straw maximum between 60-90 days.
