Biomass production of Trichoderma Viride as influenced by carbon and nitrogen sources

The biomass production of Trichoderma species is greatly influenced by the type of nutritional sources besides environmental factors. To evaluate the influence of nutrient sources on the biomass production of T. viride various carbon sources such as peptone, mannitol, glucose and nitrogen sources such as ammonium sulphate, urea and potassium nitrate were used in this study. Among the tested carbon sources, significantly highest biomass production was observed in peptone supplemented media followed by glucose and mannitol. In case of nitrogen sources, the most favoured was ammonium sulphate yielding the maximum biomass. Urea did not appear to show any positive effects on the biomass production. Combined effect of peptone with ammonium sulphate proved to be significant. Based on the present study it can be stated that Trichoderma behaves differently to different carbon and nitrogen sources, which can be used as a tool in investigating their ecological niche and nutritional requirements. | Biomass production of Trichoderma Viride as influenced by carbon and nitrogen sources
