Procoagulant constituents from Cordyceps militaris
Food Science and Human Wellness, 2018 Cordyceps militaris, belongs to Clavicipitaceae family, was investigated for its chemical compounds, and six compounds were isolated and purified by silica gel column chromatography, Sephadex LH-20 and recrystallization, and their structures were ...

Ergosterol distribution controls surface structure formation and fungal pathogenicity
mBio, 2023 Ergosterol, the major sterol in fungal membranes, is critical for defining membrane fluidity and regulating cellular processes. Although ergosterol synthesis has been well defined in model yeast, little is known about sterol organization in the context ...

Ergosterol induces mobilization of internal calcium in tobacco cells
Plant Protection Science, 2002 As for natural sterols, only ergosterol is recognized very specifically and sensitively (nM) by plants cells. Ergosterol interacts with tobacco suspension cells and trigger pH changes of extracellular medium, oxidative burst and synthesis of phytoalexins.

Journal of Fungi, 2021 Ergosterol has traditionally been used as a proxy to estimate fungal biomass as it is almost exclusively found in fungal lipid membranes. Ergosterol determination has been mostly used for fungal samples from terrestrial, freshwater, salt marsh- and ...

Applied and Environmental MicrobiologyErgosterol is an important component of fungal cell membranes and participates in the regulation of its fluidity, permeability, and material transport. In our study, we found that the ergosterol biosynthesis pathway in Aspergillus oryzae is more complex ...

Ergosterol Peroxide: a Fungal Artefact [PDF]
Nature, 1967 ALTHOUGH the isolation of ergosterol peroxide from the extracts of several different fungi has been reported1–4, the question of its authenticity as a metabolite in these cases does not seem to have been raised. In the present case, the peroxide was found to be present in extracts of sporophores of Piptoporus betulinus or of Daedalea quercina.

Ergosterol extraction: A comparison of methodologies
Access Microbiology, 2022 Ergosterol is a component of the cell membrane of mycorrhizal fungi and is frequently used to quantify their biomass. Arbuscular mycorrhizal (AM) fungi and ectomycorrhizal (ECM) fungi establish a symbiotic relationship with a respective host plant. Several methods are currently employed for quantification of ergosterol; however, these utilise a series ...

Δ8(9),22-Ergostadiene-3β-ol, an ergosterol precursor accumulated in wild-type and mutants of yeast
Journal of Lipid Research, 1972 Whereas wild-type strains of Saccharomyces cerevisiae can synthesize up to 7% dry weight of ergosterol, a polyene-resistant mutant has been obtained which produces no ergosterol. Instead, a C-28 methyl sterol is produced, and it has been identified as Δ8(

Unraveling Unique Effect of Ergosterol on Lipid Membranes, and What We Can Do with the Future STS [PDF]
Structural DynamicsErgosterol, a critical component of fungal membranes, has traditionally been thought to influence membrane properties in much the same way as cholesterol because of their similar structures.

Engineering Microbial Particles for Next‐Generation Biomedical Platforms
Advanced Science, EarlyView.Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...
