Antifungal Activity of Cinnamaldehyde Against Fusarium sambucinum Involves Inhibition of Ergosterol Biosynthesis.

Only registered users can translate articles

In this study, the antifungal effect of cinnamaldehyde against Fusarium sambucinum and its underlying mechanisms were determined.

METHODS AND RESULTS

Minimum inhibitory concentration and minimal fungicidal concentration of cinnamaldehyde were 3 and 4

Isolation and Structure Determination of Antiproliferative Secondary Metabolites from the Potato Earthball Mushroom, Scleroderma bovista (Agaricomycetes).

Only registered users can translate articles

Mycochemical examination of a methanol extract of Scleroderma bovista Fr. (Agaricomycetes) led to the isolation of 7 compounds, which were, to our knowledge, identified for the first time in this species. The chemical structures of these compounds were determined through extensive spectroscopic

Degradation and emission of carbonyl sulfide, an atmospheric trace gas, by fungi isolated from forest soil.

Only registered users can translate articles

Soil is thought to be important both as a source and a sink of carbonyl sulfide (COS) in the troposphere, but the mechanism affecting COS uptake, especially for fungi, remains uncertain. Fungal isolates that were collected randomly from forest soil showed COS-degrading ability at high frequencies:

Novel antifungal mechanism of oligochitosan by triggering apoptosis through a metacaspase-dependent mitochondrial pathway in Ceratocystis fimbriata

Only registered users can translate articles

The antifungal effects of oligochitosan (OCS) against Ceratocystis fimbriata that causes black rot disease in sweet potato and its apoptosis mechanism were evaluated. OCS restrained the mycelial growth and spores germination of C. fimbriata, and decreased the ergosterol content of cell membrane.

Chemical Composition of an Aphid Antifeedant Extract from an Endophytic Fungus, Trichoderma sp. EFI671.

Only registered users can translate articles

Botanical and fungal biopesticides, including endophytes, are in high demand given the current restrictive legislations on the use of chemical pesticides. As part of an ongoing search for new biopesticides, a series of fungal endophytes have been isolated from selected medicinal plants including

Baseline Sensitivity and Toxic Actions of Prochloraz to Sclerotinia sclerotiorum.

Only registered users can translate articles

The ergosterol biosynthesis inhibitor prochloraz is a broad-spectrum fungicide and has been registered in China since 2007 for control of the economically important necrotrophic pathogen Sclerotinia sclerotiorum. In this study, relative baseline sensitivity and toxic actions of prochloraz on S.

A sterol C-14 reductase encoded by FgERG24B is responsible for the intrinsic resistance of Fusarium graminearum to amine fungicides.

Only registered users can translate articles

Fusarium graminearum, the causal agent of wheat head blight, shows intrinsic resistance to amine fungicides. It is commonly accepted that the amines target sterol C-14 reductase and sterol Δ(8)-Δ(7) isomerase of ergosterol biosynthesis, encoded by the genes ERG24 and ERG2, respectively. Analysis of

Antiproliferative Activity and Characterization of Metabolites of Aspergillus nidulans: An Endophytic Fungus from Nyctanthes arbor-tristis Linn. against Three Human Cancer Cell Lines.

Only registered users can translate articles

BACKGROUND Endophytic fungi are receiving attention as sources of structurally novel bioactive secondary metabolites towards drug discovery from natural products. This study reports the isolation and characterization of secondary metabolites from an endophytic fungus Aspergillus nidulans, associated

Enhanced production of ligninolytic enzymes and decolorization of molasses distillery wastewater by fungi under solid state fermentation.

Only registered users can translate articles

Selected isolates of fungi were grown on wheat straw and corncob in the presence of different moistening agents such as water, molasses, potato dextrose broth and distillery effluent. All the fungal isolates responded differently with respect to growth and ligninolytic enzyme production. Fungal

Phytotoxic components produced by pathogenic Fusarium against morning glory.

Only registered users can translate articles

A pathogenic isolate of Fusarium, F. oxysporum f. sp. batatas O-17 (PF), causes wilt disease in leaf etiolation in sweet potato (Ipomoea batatas) and morning glory (Ipomoea tricolor). Extracts from PF cultures were screened for phytotoxic components using a growth inhibition assay with morning glory

Talarofuranone, a New Talaroconvolutin Analog from the Endophytic Fungus Talaromyces purpurogenus from Pouteria campechiana Seeds.

Only registered users can translate articles

An endophytic fungus Talaronyces pinpurogenus was isolated from the seeds of the popular edible fruit Pouteria campechiana. The fungus was fermented in potato dextrose agar and the fungal media were extracted with EtOAc. Chromatographic separation of the EtOAc extracts over silica gel, Sephadex

Growth and mycotoxin production by food spoilage fungi under high carbon dioxide and low oxygen atmospheres.

Only registered users can translate articles

The influence of high carbon dioxide and low oxygen concentrations on growth by the foodborne fungal species, Mucor plumbeus, Fusarium oxysporum, Byssochlamys fulva, Byssochlamys nivea, Penicillium commune, Penicillium roqueforti, Aspergillus flavus, Eurotium chevalieri and Xeromyces bisporus was
