Trichoderma is one of the fungi genera that produce important metabolites for industry. The growth of these organisms is a consequence of the nutritional sources used as also of the physical conditions employed to cultivate them. In this work, the automated Bioscreen C system was used to evaluate the influence of different nutritional sources on the growth of Trichoderma strains (T. hamatum, T....

Challenging tomato or tobacco varieties with ethylene-inducing xylanase (EIX) from the fungus Trichoderma viride causes rapid induction of plant defence responses leading to programmed cell death. Using the yeast two-hybrid system, we isolated a novel protein, tomato small ubiquitin-related modifier protein (T-SUMO), which specifically interacts with EIX. T-SUMO, a cytoplasmic protein, is a mem...

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...

The paddy straw is one of the most abundant agricultural by-products in Tamil Nadu, India. It contains approximately 37% cellulose, 24% hemicelluloses and 15% lignin. In the present investigation the paddy straw was pre-digested with Trichoderma viride and subsequently the same was utilized for the production of vermicompost by using Eudrilus eugeniae, Perionyx excavatus and Lampito mauritii un...

The objective of this research was to investigate xylanase production by filamentous fungi (Trichoderma viride) to determine the best cultivation conditions in the process, aiming toward optimization of enzyme production. The best temperature, as well as the best carbon source, for biomass production was determined through an automated turbidimetric method (Bioscreen-C). The enzyme activity of ...

The parrotfish Sparisoma viride is an abundant and ecologically important member of the tropical NW Atlantic reef fish fauna. Sagittal otoliths of 417 individuals were analysed to estimate age-based demographic variables at 4 localities (Lee Stocking Island, Barbados, Los Roques Archipelago and the San Blas Archipelago) spanning 14° of latitude. The sampling localities ranged from an area prote...

A mutant strain that secretes twice as much cellulase as its parent was obtained by irradiating conidia of Trichoderma viride QM 6a with a linear accelerator.

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...

Cellulase-producing fungi Trichoderma viride were cultured and fermented on the solid-state wheat bran fermentation medium. The characteristics of its carboxymethyl cellulase (CMCase) in the condition of this solid-state fermentation were evaluated, and the optimum culture time, optimum pH and optimum temperature for CMCase activity of T. viride fermented in this solid state were 60h, 5.0 and 5...
