| inhibition of citrus postharvest pathogens by vapor of citral and related compounds in culture. | the vapors of citral, its isomers geranial and neral, and its related compounds were examined for their effect on penicillium digitatum, penicillium italicum, and geotrichum candidum, the major fungi responsible for postharvest spoilage of citrus. vapor of citral and its two isomers generated from 15 microl l(-1) aqueous solutions in petri dishes inhibited development of the three pathogens, with concentrations of 2-6 microl l(-1) also being effective against p. italicum. vapors of citral and ge ... | 2003 | 12696950 |
| isolation and cdna cloning of novel hydrogen peroxide-dependent phenol oxidase from the basidiomycete termitomyces albuminosus. | a novel hydrogen peroxide-dependent phenol oxidase (tap) was isolated from the basidiomycete termitomyces albuminosus. tap is an extracellular monomeric enzyme with an estimated molecular weight of 67 kda. the purified enzyme can oxidize various phenolic compounds in the presence of hydrogen peroxide, but cannot oxidize 3,4-dimethoxybenzyl (veratryl) alcohol. mn(ii) was not required for catalysis by tap. the optimum ph for tap activity was 2.3, which is the lowest known optimum ph for a fungal p ... | 2003 | 12698279 |
| ustilipids, acylated beta-d-mannopyranosyl d-erythritols from ustilago maydis and geotrichum candidum. | ustilago species produce an extracellular oil that shows activity in various pharmaceutical assays. we isolated several complexes of this heterogeneous glycolipid from cultures of ustilago maydis dsm 11494 and geotrichum candidum st 002515, and determined the chemical structures of these new compounds, termed ustilipids, on the basis of nmr experiments, mass spectra, and fatty acid analyses. they all possess a 4-o-beta-d-mannopyranosyl d-erythritol basic framework, the configuration of which was ... | 2003 | 12715867 |
| dual influence of the carbon source and l-methionine on the synthesis of sulphur compounds in the cheese-ripening yeast geotrichum candidum. | the effect of the carbon source and l-methionine on the ability of geotrichum candidum to produce volatile sulphur compounds (vsc) was studied. this yeast was cultivated in a synthetic medium supplemented with various carbon sources and l-methionine at different concentrations. both glycerol and glucose significantly increased vsc production by g. candidum. unlike the effect on the l-methionine- and 4-methylthio-2-oxobutyric acid-demethiolating activities, the supply of a carbon source had a dra ... | 2003 | 12743766 |
| staphylococcus equorum subsp. linens, subsp. nov., a starter culture component for surface ripened semi-hard cheeses. | two staphylococcal strains, rp29t and rp33, were isolated from the main microflora of a surface ripened swiss mountain cheese made from raw milk. these two strains were differentiated from the most closely related species staphylococcus equorum on the basis of dna-dna hybridisation and phenotypic characteristics and are proposed as staphylococcus equorum subsp. linens subsp. nov. they could be distinguished phenotypically from s. equorum by their sensitivity to all 14 tested antibiotics, especia ... | 2003 | 12747407 |
