Biological fuel production serves as a sustainable carbon neutral energy source in this era of decreasing fossil fuels. Biogas technology is an important alternative biological fuel. In this context, this paper present the use of cheap and easily available cattle dung and cattle dung slurry for producing cellulolytic enzymes using Trichoderma reesei MTCC 164. Being rich in lignocelluloses, cattle dung and slurry are suitable for cellulolytic enzyme production.  In this study, upon optimization for fermentation conditions, it was found that sterilizing the sample by autoclaving do  not show significant  increase in  enzyme production and non-autoclaved samples showed better enzyme production. For cattle dung, concentration of 75%, 10 spores/ml Cbase (185.81U/ml), Incubation period of 15 days  showed higher activities i.e. 115.9U/ml  Cbase,  .While in case of digested biogas slurry, all parameters were more at 50% slurry concentration (i.e. 23.07U/ml Cbase) 106 spores/ml Cbase (17.79 U/ml), Incubation period of 15 days.  But the incubation period for maximum enzyme production varies with the type of enzymes and their isozymes. Out of all the three components of cellulase complex produced by Trichoderma reesei MTCC 164, cellobiase was produced to the maximum, followed by Fpase and CMCase both in cattle dung and digested biogas slurry. These enzymes can further be purified for commercial purpose.
