Non-Stereotypical Distribution and Effect of Ergosterol in Lipid Membranes [PDF]

open access: yes
Sterols are an important class of lipids that regulate many biological processes. Among them, ergosterol in fungi and some protists is surprisingly understudied compared to cholesterol from animal membranes.

Procoagulant constituents from Cordyceps militaris

open access: yesFood 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

open access: yesmBio, 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

open access: yesPlant 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.

Microbial community dynamics during composting of sewage sludge and straw studied through phospholipid and neutral lipid analysis [PDF]

open access: yes, 2008
The composting process involves a succession of different communities of microorganisms that decompose the initial material, transforming it into a stable final product. In thiswork, the levels of phospholipid fatty acid (PLFA), neutral lipid fatty acid (

Pseudomonas lipase catalyzed synthesis of ergosterol oleate [PDF]

open access: yes, 2011
In the present study, the potential of bacterial lipase isolated from Pseudomonas aeruginosa NCATM (P) B 001380 to catalyze the esterification of ergosterol with oleic acid in the simple process, was evaluated. The prepared ergosterol oleate was purified

Specific perception of ergosterol by plant cells [PDF]

open access: yes, 2003
Ergosterol (a fungal membrane component) induced modification of proton fluxes and membrane yperpolarization in motor cells of Mimosa pudica. These reactions appear specific since they were not induced by the other sterols tested.

Ergosterol Peroxide: a Fungal Artefact [PDF]

open access: yesNature, 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.

Expression pattern, subcellular localization of Aspergillus oryzae ergosterol synthases, and their effects on ergosterol and fatty acid metabolism

open access: yesApplied and Environmental Microbiology
Ergosterol 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 ...

Adapting an Ergosterol Extraction Method with Marine Yeasts for the Quantification of Oceanic Fungal Biomass

open access: yesJournal 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 ...
