Enhancement of Xylanase Production by Protoplast Fusion of Trichoderma spp.
Filamentous fungi Trichoderma spp. are efficient hyper-producers of industrially important enzymes. Xylanases are essential hemicellulases having vast ranges of applications in the various industrial sectors. In this study, the protoplast fusion of two T. virens and </span...
متن کاملInfluence of protoplast fusion between two Trichoderma spp. on extracellular enzymes production and antagonistic activity
Biological control plays a crucial role in grapevine pathogens disease management. The cell-wall degrading enzymes chitinase, cellulase and β-glucanase have been suggested to be essential for the mycoparasitism activity of Trichoderma species against grapevine fungal pathogens. In order to develop a useful strain as a single source of these vital enzymes, it was intended to incorporate the char...
متن کاملIntraspecific hybridisation of Trichoderma pseudokoningii by anastomosis and by protoplast fusion.
Double auxotrophic and morphological mutants of Trichoderma pseudokoningii Rifai were fused by anastomosis and by protoplast fusion. The recovery of recombinants from heterokaryons on different selective media and from heterokaryotic colonies indicated the occurrence of parasexual events. Prototrophic colonies growing on minimal medium produced binucleate spores, green in colour, revealing a no...
متن کاملComparative Study of Cellulase Production by Aspergillus niger and Trichoderma viride Using Solid State Fermentation On Cellulosic Substrates Corncob, Cane Bagasse and Sawdust
The enzyme activities of Trichoderma viride and Aspergillus niger grown on various waste cellulosic materials such as corncobs, saw dust and sugarcane baggase were tested for a period of 192 hrs. The maximum activity of 0.33 mg/min/ml & 0.026 mg/min/ml of cellulase enzyme were found to be produced on saw dust after 144 hrs by Aspergillus niger & Trichoderma viride, respectively. Corncob showed ...
متن کاملSuppression of Pratylenchus penetrans and Tylenchorhynchus dubius by Trichoderma viride.
Trichoderma spp. are common soil fungi which influence tile development of plant-pathogenic fungi in the soil (1, 8). Yang et al. (9) found that T. harzianum influenced the severity of Fusarium wilt of cotton in the presence of Meloidogyne incognita. We report herein that the survival of two other plant-parasitic nematodes also was influenced by addit ion of cornminuted cultures of Trichoderrna...
