| coordination chemistry of microbial iron transport compounds: rhodotorulic acid and iron uptake in rhodotorula pilimanae. | the mechanism by which iron uptake is facilitated by the siderophore rhodotorulic acid (ra) in the yeast rhodotorula pilimanae was investigated with radioactively labeled fe and ra and kinetically inert, chromic-substituted ra complexes. the weight of the evidence supports a model in which ra mediates iron transport to the cell but does not actually transport iron into the cell. it is proposed that ra exchanges the ferric ion at the cell surface with a membrane-bound chelating agent that complet ... | 1978 | 30750 |
| [infrared spectrum of yeast cell walls]. | infrared spectra of whole cells and cell walls were studied with schizosaccharomyces pombe, endomyces magnusii. rhodotorula rubra, and candida lipolytica. qualitative analysis of the spectra and comparison of the spectra recorded for the cells and for their walls led to a conclusion that, contrary to the common viewpoint, an ir spectrum of the whole cell of any yeast species was determined by the components contained in the cell rather wall than by all components of the cell. | 1977 | 895561 |
| acid phosphatase of the yeast rhodotorula rubra. purification and properties of the enzyme. | 1. acid phosphatase from the yeast rhodotorula rubra was purified 44-fold. the purification procedure involved mechanical disruption of cells, precipitation with ethanol, chromatography on deae- and cm-cellulose. 2. the purified enzyme is homogeneous in polyacrylamide gels at ph 4.5, 9.5 and 8.4. carbohydrate content accounts for 57% of the total weight. the optimum ph is at 4.0-4.6, and the enzyme is stable over ph range from 2.6 to 6.0. full activity was retained on 60-min incubation at 50 deg ... | 1977 | 17985 |
| the development of new iron-chelating drugs. | 2,3-dihydroxybenzoic acid has been identified as a potentially useful iron-chelating drug. accordingly, we have evaluated a series of derivatives of hydroxylated benzoic acids for their ability to induce iron excretion in the iron-overloaded rat. in addition, we have examined a number of hydroxamic acids and some other naturally occurring iron-chelating agents. of the 26 benzoic acid derivatives studied, none appeared to be more effective than 2,3-dihydroxybenzoic acid, for reasons which are dis ... | 1976 | 1255491 |
| lipid composition of 30 species of yeast. | the detailed composition of cellular lipid of more than 23 species of yeast has been determined quantitatively by thinchrography on quartz rods, a method previously used for estimating cellular lipids of seven species of yeast. that data was fortified by neutral and phospholipid quantitations on 30 species of yeast cells. most of the test organisms contained 7-15% total lipid and 3-6% total phospholipid per dry cell weight, except for the extremely high accumulation of triglycerides in two speci ... | 1976 | 1011938 |
| [studies on the cell wall of yeast of the genus rhodotorula. x. isolation and purification of cell-wall glycoproteins from rhodotorula rubra (author's transl)]. | following ethylene diamine treatment of the cell wall of rhodotorula rubra, a water soluble fraction has been isolated. this fraction can be resolved into three glycoproteins and one protein. the major part is a glycoprotein, purified to homogeneity which has a molecular weight of 64 000. the glyco-part of this protein contains mannose, glucose and one residue of glucosamine. after pronase treatment, the presence of an ""asparaginyl-n-acetylglucosamine" linkage is established by the existence of ... | 1976 | 943181 |
| [study of the rhodotorula rubra cell wall. vii influence of chloramphenicol on its morphology and phosphatase activity (author's transl)]. | rh. rubra grown in the presence of chloramphenicol (500 mug/ml of medium) displayed morphological and biological changes, including formation of aberrant mitochondria with altered cristae, increase of the ratio fundamental element/mucilaginous sheath and electron-transparent regions in the cell walls. after treatment of the yeast with trypsin or beta-glucanase complex, acid and alkaline phosphatases remained localised within the cell wall, but the effect of the degradative enzymes on the activit ... | 1976 | 943241 |

| mycotic flora of the interdigital spaces of the human foot: a preliminary investigation. | a qualitative and quantitative study of the mycotic flora of the interdigital spaces of 27 male volunteers yielded 1,291 moulds and 598 yeasts. concurrently, a study of garden soil was conducted in order to obtain data concerning the transient-resident status of the fungi recovered from the feet. of the 120 genera and species of fungi isolated, 51 were recovered from the volunteers, 53 from the soil, and 16 from both categories. the most commonly recovered fungi from the toewebs, in order to occ ... | 1975 | 1143314 |

| [effect of yeast mannans on aldolase of rat blood serum]. | the activity of aldolase in rat blood serum was studied in experiments in vitro and in vivo as affected by extracellular mannan of rhodotorula rubra. it was established that in vitro the polysaccharide has an inhibitory effect in the enzyme and in vivo, vice versa, activates it. the maximal activation is observed against a background of the v increase and km decrease. by the preparative electrophoresis in 7.5% polyakrylamide gel seven isoenzymes of aldolase are obtained. after introduction of th ... | 1975 | 1209756 |
