Abstract

The present study examines the lignocellulose degradation in solid state fermentation in sugarcane bagasse and rice straw by Aspergillus tamarii over a period of 21 days. Lignocellulose degradation in sugarcane bagasse and rice straw, fortified with glucose was studied with and without ammonium sulphate. In bagasse fermentation, when the substrate initially containing 17.4% lignin was fortified with 5% glucose in the absence of ammonium sulphate, a maximum lignin loss of 24.7, was recorded. This maximum lignin loss was accompanied by a minimum cellulose loss of 3. In rice straw, fermentation under the same conditions resulted in a maximum lignin loss of 45.5% and 2.8% loss of cellulose. Efficiency of solid state fermentation using the two different substrates indicates that lignin loss is high in comparison to cellulose loss.  

Key words: lignin, cellulose, fortification, white rot fungi
