Antagonistic capacity of Trichoderma harzianum compared to Rhizotecnia, Nakataea sigmoidea, Sclerotium rolfsii and its effect in native strains of Trichoderma isolated form rice crops

Selection of high temperature and salinity tolerant Trichoderma isolates with antagonistic activity against Sclerotium rolfsii

Trichoderma isolates were collected from varied agro-climatic zones of India and screened for high temperature and salinity tolerance. Among all the isolates tested, T. asperellum, TaDOR673 was highly tolerant to heat shock of 52°C with a mean spore count (log c.f.u/ml) of 4.33. The isolate after recovery from heat shock possessed higher germination rate and biomass production compared to its w...

The improvement of competitive saprophytic capabilities of Trichoderma species through the use of chemical mutagens

The antagonistic potential of Trichoderma strains was assayed by studying the effect of their culture filtrate on the radial growth of Sclerotium rolfsii, the causal agent of chickpea collar rot. Trichoderma harzianum-1432 (42.2%) and Trichoderma atroviride (40.3%) were found to be strong antagonists. To enhance their antagonistic potential, mutagenesis of these two selected strains was perform...

Fungal Biomass Protein Production from Trichoderma harzianum Using Rice Polishing

Industrially important enzymes and microbial biomass proteins have been produced from fungi for more than 50 years. High levels of crude protein as much as 45% are present in fungal biomass with balanced essential amino acids. The aim of this study was to access the potential of Trichoderma harzianum to produce fungal biomass protein from rice polishings. Maximum biomass yield was obtained at 5...

Fungicidal compounds from a marine Ascidian - associated fungus

A marine Ascidian-associated fungus, Trichoderma harzianum, (NIO/BCC2000-51) was assessed for its in vitro antagonistic activity against ten fungal phytopathogens and three food-infesting fungi. Fractionation of the cell-free culture filtrate of T. harzianum (NIO/BCC2000-51) showed its ethyl acetate (EA) fraction to be significantly active against fungal phytopathogens; Macrophomina sp, Pyricul...
