The aim of this study was to evaluate and validate the efficiency of 12C6+ irradiation of Aspergillus niger (A. niger) or mutagenesis via mixed Trichoderma viride (T. viride) culturing as well as a liquid cultivation method for cellulase production via mixed Trichoderma reesei (T. reesei) and A. niger culture fermentation. The first mutagenesis approach was employed to optimize yield from a cel...

There is no doubt in the fact that preparations containing Trichoderma as main component are currently a real alternative to synthetic agrochemicals antagonists of soil-borne plant diseases and growth stimulators. The use this kind drugs does not always give sufficiently stable results. In addition, technological problems can often arise, which associated with short shelf life liquid based on T...

ADEROLU, Ademola Zaid, Eustace. A. IYAYI and Abiodun A. ONILUDE, 2007. Changes in nutritional value of rice husk during Trichoderma viride degradation. Bulg. J. Agric. Sci., 13: 583-589 Possible improvement in nutritional status of rice husk using Trichoderma viride a fungus was investigated over a period of 40 days. Proximate composition was significantly (P<0.05) improved with microbial treat...

More than 200 recent collections of Trichoderma from China were examined and 16 species belonging to the Viride clade were identified based on integrated studies of phenotypic and molecular data. Among them, seven wood-inhabiting new species, T. albofulvopsis, T. densum, T. laevisporum, T. sinokoningii, T. sparsum, T. sphaerosporum and T. subviride, are found. They form trichoderma- to verticil...

The effect of two fungicides, Caocobre and Ridomil on rhizosphere phenomenon of Cocoa (Theobroma cacao L) seedlings has been studied at different stages of the development of the plant growing in pots. Fungal population in the rhizophere soil was generally higher than in the non-rhizosphere soil. The total number of fungal population in both the rhizosphere and non-rhizosphere was highest on th...

Azalomycin F (AMF), a macrocyclic lactone antibiotic, in concentrations of 10(-5) g/ml (10(-6) - 10(-5) mol/l) was found to stimulate both the 45Ca2+ influx and efflux in intact Trichoderma viride submerged mycelium and in cells of Saccharomyces cerevisiae without having Ca2+ ionophoric properties. AMF also inhibited ATP-dependent Ca2+ uptake in membrane fractions prepared from T. viride submer...

Two enzymatic extracts obtained from xylan-grown Aspergillus terreus CCMI 498 and cellulose-grown Trichoderma viride CCMI 84 were characterised for different glycanase activities. Both strains produce extracellular endoxylanase and endoglucanase enzymes. The enzymes optimal activity was found in the temperature range of 45-60 degrees C. Endoglucanase systems show identical activity profiles tow...
