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 کاملInterspecific complementation analysis by protoplast fusion of Candida tropicalis and Candida albicans adenine auxotrophs.
A protocol employing inositol starvation was used to isolate proline and adenine auxotrophs of Candida tropicalis. Interspecific hybrids between red adenine auxotrophs of C. tropicalis and Candida albicans were formed by protoplast fusion. These C. tropicalis red adenine auxotrophs were shown to fall into two complementation groups by crossing them with a known C. albicans ade1 tester strain. I...
متن کاملEffects of Protoplast Fusion on δ-endotoxin Production in Bacillus thuringiensis Spp. (H14)
In this study, mutant forms of Bacillus thuringiensis spp. israelensis (H14) were produced. These mutants were identified when the cells were cultured on chloramphenicol plates and stained with crystal violet. Protoplasts of the mutants were isolated by enzymatic digestion (lysozyme) of the cell walls at the presence of an osmotic stabilizer. The protoplasts were induced to fuse to each other i...
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 کاملProtoplast Culture and Fusion between Brassica Carinata and Brassica Napus
In this study, attempts were made to select in vitro responsible genotypes and to fuse the isolated protoplasts of Brassica carinata and Brassica napus breeding lines (BC DH Dodolla, BC DH -1, BC DH-6 and BN OP-1, BN-SL03/04), obtained from our previous experiments. Combination of three different PEG concentrations (20%, 25% or 30%) and two different treatment durations (15 and 20 min.) were te...
