| the regulated catabolism of endogenous and exogenous phosphatidylinositol by saccharomyces cerevisiae leading to extracellular glycerophosphorylinositol and inositol. | it was previously shown that phosphatidylinositol catabolism leads to the accumulation of glycerophosphorylinositol in the culture medium of saccharomyces cerevisiae. we now find that lack of an energy source (glucose) reduces the formation of glycerophosphorylinositol and increases extra-cellular inositol. this situation is reversed by refeeding glucose. [3h]phosphatidylinositol is the precursor of extra-cellular [3h]inositol with energy-starved cells. extracellular glycerophosphorylcholine and ... | 1975 | 166987 |

| the conversion of 3-hydroxy-2,4,5-trihydroxymethylpyridine into pyridoxine by kloeckera apiculata. | kloeckera apiculata, a vitamin b-6-dependent yeast, grows in the presence of 3-hydroxy-2,4,5-trihydroxymethylpyridine in vitamin b-6-free media. on a molar basis the growth-promoting activity of this compound is approximately one-tenth that of other forms of vitamin b-6. [g-3h]3-hydroxy-2,4,5-trihydroxymethylpyridine is converted into radioactive vitamin b-6 compounds of the same specific radioactivity by growing cultures of k. apiculata. | 1976 | 1275911 |
| activity of different 'killer' yeasts on strains of yeast species undesirable in the food industry. | killer strains of the genera saccharomyces, hansenula and kluyveromyces were tested for killing activity against yeasts that cause trouble in the food industry (in the genera zygosaccharomyces, kloeckera, saccharomycodes and schizosaccharomyces). saccharomyces strains killed only zygosaccharomyces rouxii strains, while non-saccharomyces strains showed a wider anti-yeast spectrum. the kluyveromyces phaffii killer strain was of particular interest because of its killer action against kloeckera api ... | 1991 | 1769559 |
| contribution of different yeasts isolated from musts of monastrell grapes to the aroma of wine. | volatile substances of wines obtained by fermentation of musts from 'monastrell' grapes (alicante, spain) was studied for yeast isolated from such musts. the results of the statistical treatment performed show the importance of yeasts of low fermentative power, particularly kloeckera apiculata, in the production of volatile substances. saccharomyces cerevisiae var. chevalieri was found to be the most important yeast of high fermentative power. | 1991 | 1777384 |
| physiological variants of saccharomyces cerevisiae and kloeckera apiculata from palm wine and cashew juice. | physiological variants of saccharomyces cerevisiae and kloeckera apiculata have been identified in oil palm wine and cashew juice from nigeria. genomic dna from the four s. cerevisiae variants had a % g + c of 36-41% while that of k. apiculata was 32.2%. fermentation of cashew juice produced wine of alcoholic contents of 10% with s. cerevisiae, 8% with k. apiculata and 9.3% with both yeasts simultaneously. | 1990 | 2196256 |
| killer toxin of hanseniaspora uvarum. | the yeast hanseniaspora uvarum liberates a killer toxin lethal to sensitive strains of the species saccharomyces cerevisiae. secretion of this killer toxin was inhibited by tunicamycin, an inhibitor of n-glycosylation, although the mature killer protein did not show any detectable carbohydrate structures. culture supernatants of the killer strain were concentrated by ultrafiltration and the extracellular killer toxin was precipitated with ethanol and purified by ion exchange chromatography. sds- ... | 1990 | 2206104 |

| glucose metabolism, enzymic analysis and product formation in chemostat culture of hanseniaspora uvarum. | the physiology of hanseniaspora uvarum k5 was studied in glucose-limited chemostat cultures and upon glucose pulse. up to a dilution rate of 0.28 h-1, glucose was completely metabolized in biomass and co2. above this value, increase in the dilution rate was accompanied by sequential production of metabolites (glycerol, acetate and ethanol) and decrease in cell yield. similar results were observed upon glucose pulse. from the enzyme activities (pyruvate dehydrogenase, pyruvate decarboxylase, nad ... | 1995 | 7785333 |
| "hanseniaspora uvarum" the ultrastructural morphology of a rare ascomycete, isolated from oral thrush. | superficial fungal infections, including oral thrush, often affect aged full denture wearers and many individuals over 65 years old. the aim of this study was to examine the ultrastructural morphology of a very rare yeast, named hanseniaspora uvarum/guillermondi, member of the ascomycetes family, whose pathogenesis and behaviour is not widely known. the yeast was isolated from whitish lesions of the buccal mucosa of an 70 years old woman. the specimen was collected with a mouth swab and cultured ... | 1994 | 7994154 |
| relationship between ethanol tolerance, lipid composition and plasma membrane fluidity in saccharomyces cerevisiae and kloeckera apiculata. | the lipid composition of a strain of each of two yeasts, saccharomyces cerevisiae and kloeckera apiculata, with different ethanol tolerances, was determined for cells grown with or without added ethanol. an increase in the proportion of ergosterol, unsaturated fatty acid levels and the maintenance of phospholipid biosynthesis seemed to be responsible for ethanol tolerance. the association of ethanol tolerance of yeast cells with plasma membrane fluidity, measured by fluorescence anisotropy, is d ... | 1994 | 8001764 |
