Ochratoxin production by the Aspergillus ochraceus group and Aspergillus alliaceus.
Ochratoxin A is a toxic and carcinogenic fungal secondary metabolite; its presence in foods is increasingly regulated. Various fungi are known to produce ochratoxins, but it is not known which species produce ochratoxins consistently and which species cause ochratoxin contamination of various crops. We isolated fungi in the Aspergillus ochraceus group (section Circumdati) and Aspergillus alliac...
متن کاملMicrobiological hydroxylation of estradiol: formation of 2- and 4-hydroxyestradiol by Aspergillus alliaceus.
Microorganisms known to hydroxylate alkaloids, amino acids, and aromatic substrates were examined for their potential to hydroxylate 17 beta-estradiol and estrone. Thin-layer chromatography of fermentation extracts revealed a wide range of steroid products. Aspergillus alliaceus (UI 315) was the only culture capable of producing good yields of catechol estrogens with 17 beta-estradiol. The orga...
متن کاملAsperlicin, a novel non-peptidal cholecystokinin antagonist from Aspergillus alliaceus. Fermentation, isolation and biological properties.
The fermentation and isolation of a new, non-peptide cholecystokinin antagonist, asperlicin, produced by Aspergillus alliaceus is described. The potent and specific interaction of asperlicin with cholecystokinin receptors was shown using in vitro biochemical assays.
متن کاملA potent nonpeptide cholecystokinin antagonist selective for peripheral tissues isolated from Aspergillus alliaceus.
A new, competitive, nonpeptide cholecystokinin (CCK) antagonist, asperlicin, was isolated from the fungus Aspergillus alliaceus. The compound has 300 to 400 times the affinity for pancreatic, ileal, and gallbladder CCK receptors than proglumide, a standard agent of this class. Moreover, asperlicin is highly selective for peripheral CCK receptors relative to brain CCK and gastrin receptors. Sinc...
متن کاملSex Hormones and Macronutrient Metabolism
The biological differences between males and females are determined by a different set of genes and by a different reactivity to environmental stimuli, including the diet, in general. These differences are further emphasized and driven by the exposure to a different hormone flux throughout the life. These differences have not been taken into appropriate consideration by the scientific community...
