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...

HIGHLIGHTS Trichoderma inoculation increased the total biomass, seedling height, root length, area, diameter, number of tips, and growth potential seedlings. increases resistance bean plant to Rhizoctonia pathogen. Among improved isolates Trichoderma, ChBD13 ChBD15 showed better performance in terms growth.

A study of the distribution of fungal microflora was conducted on the sediment of Lake Alimini Grande in order to contribute to the evaluation of the ecosystem characteristics that can effect the process of decomposition. The isolation and identification of fungal species and ergosterol analysis were performed on sediment samples taken from 33 monitoring stations in autumn and winter. Altogethe...

The present study is an attempt to isolate and optimize the fermentation conditions of three fungus, namely Trichoderma virens, Alternaria alternata and Curvularia lunata to get pigments for the purpose of textile dyeing. Highest optical density has been achieved in potato dextrose broth at 28oC in 25 days under static conditions. Wool and silk are dyed unmordanted with very good wash and rub f...

We have isolated three novel strains of Trichoderma (two T. harzianum and one T. atroviride) from wild mushroom and tree bark, and evaluated their biocontrol potential against Sclerotium delphinii infecting cultivated cotton seedlings. T. harzianum strain CICR-G, isolated as a natural mycoparasite on a tree-pathogenic Ganoderma sp. exhibited the highest disease suppression ability. This isolate...

Trichoderma harzianum is a ubiquitous species in the environment and is effective in the biological control of plant-pathogenic fungi. T. harzianum has not been linked unequivocally to its sexual state nor has its phylogeny been studied in detail. It has been suggested that T. harzianum is a species complex based on the phenotypic and genotypic variability encountered. On the basis of morpholog...

Glucanase enzyme isolated from Trichoderma isolates were purified to homogeneity using ammonium persulphate precipitation and Fast Protein Liquid Chromatography. Purity of the isolated enzyme was confirmed by SDS-PAGE. Enzymatic properties such as effect of temperature, pH, SDS and EDTA were determined. Molecular weight of Trichoderma isolates was found to be around 55 kDa. The optimum temperat...

background and objectives: different trichoderma species play role as suitable alternative for chemical fertilizers and successful biological tool in stable agriculture. these microorganisms show rivalry in food and place sources. they establish in the rhizosphere of most agricultural and non-agricultural plants via producing spores. they also could induce resistance in plants. these properties...
