متن کاملStrain Improvement of Trichoderma Harzianum by Uv Mutagenesis for Enhancing It’s Biocontrol Potential against Aflotoxigenic Aspergillus
Trichoderma is an opportunistic, avirulent plant symbiont. Chitin is the main structural component of fungi, enzyme responsible to metabolize the chitin and various techniques to enhance the chitinolytic enzyme production at the genetic level are receiving great attention to develop the efficient biocontrol agent. UV mutagenesis was found to be one of the novel strategy for developing Trichoder...
متن کاملProtease over-production in the presence of copper by a Trichoderma harzianum strain with biocontrol potential
The effect of copper on the production of extracellular trypsin-like proteases of Trichoderma harzianum T66 was examined. Trypsin-like protease enzyme activities were significantly enhanced in the presence of copper ion. It was demonstrated that instead of raising the activity of previously produced enzymes, copper ions are able to induce the secretion of extracellular trypsin-like proteases. S...
متن کاملOptimization of Fungal Enzyme Production by Trichoderma harzianum KUC1716 through Surfactant-Induced Morphological Changes
The morphological optimization of Trichoderma harzianum was carried out using several surfactants to achieve increased cellulase production. Addition of the surfactants to the culture medium successfully modified the fungal morphology from an aggregated form to a dispersed form. Optimization of the fungal morphology increased cellulase activity up to 177%. The morphologically optimized conditio...
متن کاملSelf-fusion of protoplasts enhances chitinase production and biocontrol activity in Trichoderma harzianum.
Protoplasts were isolated from Trichoderma harzianum strain PTh18 using lysing enzymes and self-fusion of T. harzianum protoplasts was carried out using polyethylene glycol in STC buffer. The fused protoplasts of T. harzianum were regenerated and 15 self-fusants were selected to study the chitinase production and biocontrol activity. High chitinase activity was measured in the culture filtrates...
