The efficacy of four fungal bioagents viz., Trichoderma hamatum, Trichoderma harzianum, Trichoderma viride, Gliocladium virens and two bacterial bioagents namely Pseudomonas fluorescens and Bacillus subtilis were evaluated against the chickpea vascular wilt pathogen, Fusarium oxysporum f.sp. ciceri in vitro condition using Dual Culture Technique. Among the fungal bioagents, T. harzianum produce...

The aim of this work is to select filamentous fungal strains isolated from saw dust, soil, and decaying wood with the potential to produce xylanase and cellulase enzymes. A total of 110 fungi were isolated. Fifty-seven (57) of these fungi were isolated from soil samples, 32 from sawdust, and 19 from decaying wood. Trichoderma and Aspergillus had the highest relative occurrence of 42.6% and 40.8...

The present experiment aimed at increasing orange peel and sugar beet pulp protein content through solid-state fermentation by Trichoderma reesei and Trichoderma viride. In vitro digestibility and changes in the chemical composition of the fermented products were determined after seven days of fungal cultivation using gas production tests. The cultivation of T. reesei and T. viride on orange pe...

Fungi commonly known for diseases generating and fermentation agents, apart from this some fungi show biodegradation agents. Pesticides are used for controlling plant diseases but when spraying the pesticides only 40% goes at target and the rest in soil environment. So the soil be contaminated and as a result of this useful microflora are affected and soil fertility decline. So, some fungi test...

A major part of Trichoderma antifungal system consists of a number of genes encoding for an astonishing variety of secreted lytic enzymes including; e.g. chitinase, cellulases and β-1,3glucanases. The present work aimed to apply the mutagenesis technique in genetically breeding program of the bioagent Trichoderma viride to enhance three effective hydrolytic enzymes in their biocontrol abilities...

Lentinula edodes, one of the most important edible mushrooms in China, is affected heavily by the infection of green mold that overgrows mushroom mycelia. We collected the diseased samples from main L. edodes cultivation regions in China to characterize the pathogen and to study the effect of Trichoderma spp. on L. edodes species. We identified six Trichoderma species, that is, T. harzianum, T....

Antibiotic U-22,324 is a polypeptide produced by the fungus Trichoderma viride. Cycloheximide was found to block gross cellular protein synthesis of T. viride with little interference with antibiotic synthesis. No radioactive label was recovered in the ribosomes when labeled amino acids and cycloheximide were added to a culture at the onset of peptide synthesis although net antibiotic synthesis...

The most common biological control agents (BCAs) of the genus Trichoderma have been reported to be strains of Trichoderma virens, T. harzianum, and T. viride. Since Trichoderma BCAs use different mechanisms of biocontrol, it is very important to explore the synergistic effects expressed by different genotypes for their practical use in agriculture. Characterization of 16 biocontrol strains, pre...

In the field of natural products chemistry, a common question pertains to the authenticity of an isolated compound, i.e. are the interesting side chains biosynthesized naturally or an artefact of the isolation/purification processes? The droplet-liquid microjunction-surface sampling probe (droplet-LMJ-SSP) coupled to a hyphenated system (UPLC-UV-HRESIMS) empowers the analysis of natural product...

Humic acids (HA) were produced by a Trichoderma viride strain under submerged fermentation in a medium based on the oil palm empty fruit bunch (EFB) and the main variables of the process were optimized by using response surface methodology. A temperature of 40°C and concentrations of 50g/L EFB, 5.7g/L potato peptone and 0.11g/L (NH4)2SO4 were the optimum levels of the variables that maximize th...
