the effects of bio-priming with different isolates of biological agent of trichoderma spp. and pseudomonas fluorescens on morphological and physiological characteristics of a bean cultivar (yaas) as well as their effects on controlling of rhizoctonia solani were investigated in two separate experiments. in the first experiment, different isolates of trichoderma including trichoderma harzianum b...

Forest ecosystem harbour a large number of biotic components where cellulolytic microorganisms participate actively in the biotransformation of dead and decaying organic matter and soil nutrient cycling. This study explores the aerobic culturable cellulolytic microorganisms in the forest soils of North East India. Soil samples rich in dead and decaying organic matter were collected from eight c...

We examined the mycoparasitic and saprotrophic behavior of isolates representing groups of Trichoderma harzianum to establish a mechanism for the aggressiveness towards Agaricus bisporus in infested commercial compost. Mycoparasitic structures were infrequently observed in interaction zones on various media, including compost, with cryoscanning electron microscopy. T. harzianum grows prolifical...

Abstract Filamentous fungi are crucial for recycling of organic material in nature. In natural habitats, they cope with many stress factors and therefore their adaptation ability to various conditions is very high. Trichoderma sp., used agriculture as biocontrol agent, exposed a variety toxic molecules including pesticides fungicides. They have fight using mechanisms known the response. Adaptat...
