The study was aimed to carry out experiments to determine the optimal parameters for the biomass production of Trichoderma. It is quite essential to determine the physical conditions that are favorable for the growth of Trichoderma species. The seven species under study have been isolated from the rhizospheric soils of chickpea; pigeon pea and lentil crops of different areas of an Indian State (Uttar Pradesh) and these were later tested in vitro at different pH, temperatures and varying…

Trichoderma from Extreme Environments: Physiology, Diversity, and Antagonistic Activity

In this chapter I focus on important parameters that have large effects on growth, bioactivity, and antagonism as biological control agents of Trichoderma: temperature, pH, nutrient substrate, and water potential, and minor factors such as light and humidity.

The Influence of Temperature on the Growth, Sporulation, Colonization, and Survival of Trichoderma spp. in Grapevine Pruning Wounds

Native Trichoderma native strains are better adapted to survive in a changing environment, and they could give better protection to grapevine plants in co-evolution with each specific vineyard.

Comparative Study on the Activity of Trichoderma asperellum and T. Album and Their Role in Controlling Faba Bean Root Rot and Wilt Diseases

richoderma spp are the most important soil fungi in Egypt. This study was initiated to evaluate Trichoderma asperellum and T. album used to produce Bio-Nagi and Bio-Zeid biocide products,

Application of a Posttreatment to Improve the Viability and Antifungal Activity of Trichoderma asperellum Biomass Obtained in a Bioreactor during Submerged Cultivation

All the post-treatment methods studied improved the viability and antifungal activity of Trichoderma, at least in terms of the area of the colonized surface.

Evaluation of biocontrol potential of native Trichoderma isolates against charcoal rot of strawberry

Trichoderma is a highly beneficial species for use in agriculture due to its ability to combat soilborne disease and increase growth in plants. This study investigated the effects of the biological

Effect of Different Temperature and Culture Media on the Mycelia Growth of Trichoderma viride Isolates

Trichoderma sp. are free-living filamentous fungi that are common in soil and root ecosystems. They are opportunistic, avirulent plant symbionts, as well as being parasites of other fungi (Harman et

The in vitro test revealed the potential antagonist of Trichoderma spp.



Effects of temperature, pH and water potential on growth of four fungi with disease biocontrol potential

G20 and three Trichoderma isolates and growth rates were lower on potato/dextrose agar with water potential adjusted with polyethylene glycol than when adjusted with NaCl or glycerol and no mycelial growth or spore germination occurred on agar at-14.0 MPa.

Aims:  Water activity (aw) and pH are probably the most important environmental parameters affecting the activities of mycoparasitic Trichoderma strains. Therefore it is important to collect

Effect of Media, Temperature, pH and Light on the Growth and Sporulation of Fusarium oxysporum f. sp. Lini (Bolley) Snyder and Hensan

Out of ten different media studied, Fusarium oxysporum f. sp. lini grew well on linseed and maize meal media. It required optimum temperature of 25 ± 20C for the growth and sporulation and grew well

Effect of Agitation Speed on Morphological Changes in Aspergillus niger Hyphae During Production of Tannase

There were significant correlations between the speed of agitation and the hyphal morphology including its internal structures and the activity of enzyme production and this could be due to the excessive cell permeability related to abrasion by shear forces and also by oxygen limitation.
