Abstract
Seven different species of Trichoderma isolated from the different locations of Uttar Pradesh were used in this study. A comparative analysis was done among all the seven species for the determination of glucanase enzyme production and nitrogen content determination the results showed that among all the seven tested species, Trichoderma harzianum shows the highest glucanase enzyme production as well as the highest nitrogen content. Optimal physical parameters such as pH, temperature, and effect of agitation were also tested for the biomass production on all the eight species. The results revealed that the optimal pH temp and agitation speed for Trichoderma biomass production were 6.0 and 6.5, 25 and 30°C and 150 rpm. In present study we also evaluated the effect of two different carbon sources on the glucanase enzyme induction. Carboxymethyl cellulose (CMC) was found to be the best carbon source for glucanase enzyme induction. Key words: Trichoderma, nitrogen content, biological control.
