| ascorbic acid specific utilization by some yeasts. | one hundred and eighty strains of yeasts belonging to 17 genus and 53 species were screened for their ability to grow on ascorbic acid and iso-ascorbic acid as the sole carbon source. most of the tested strains (157) were unable to grow on either compound. strains of seven species of the genus cryptococcus, of two candida species, of filobasidiella neoformans, trichosporon cutaneum, lipomyces starkeyi, hansenula capsulata, and one strain of aureobasidium pullulans were able to grow on ascorbic a ... | 1986 | 3779527 |
| resistance of yeast flora of labaneh to potassium sorbate and sodium benzoate. | ten yeast cultures belonging to eight species representing the yeast flora of labaneh were tested for their resistance to potassium sorbate and sodium benzoate. changes in counts were monitored after 7, 14, and 21 d at 5 degrees c in yeast-free labaneh containing different concentrations of potassium sorbate or sodium benzoate. more than 400 mg/kg of sodium benzoate were needed to limit the counts of saccharomyces cerevisiae (biovariants 1, 2, and 7) cryptococcus curvatus, pichia farinosa, candi ... | 1997 | 9361202 |
| influence of the dilution rate on the bioproductivity of lactose-utilizing yeasts: fuzzy logic modeling. | the studied problem is of commercial interest because whey, the cultivation substrate, is a waste by-product from the transformation of milk into cheese and casein. investigations on the influence of the dilution rate (d) on the bioproductivity of lactose-utilizing yeasts were carried out with two model strains--the oxidative strain candida blankii 35 and the fermentative strain candida pseudotropicalis 11. the increase of d led to the different changes in productivity. the best synthesizing abi ... | 2003 | 12872933 |
| candida digboiensis sp. nov., a novel anamorphic yeast species from an acidic tar sludge-contaminated oilfield. | two strains (teri-6(t) and teri-7) of a novel yeast species were isolated from acidic tar sludge-contaminated soil samples collected from digboi refinery, assam, india. these two yeast strains were morphologically, physiologically and phylogenetically identical to each other. no sexual reproduction was observed on corn meal, malt, gorodkowa, ym or v8 agars. physiologically, the novel isolates were most closely related to candida blankii, but differed in eight physiological tests. the prominent d ... | 2005 | 15774693 |
| chemostat cultivation of candida blankii on sugar cane bagasse hemicellulose hydrolysate. | a candida blankii yeast isolate was grown in sugar cane bagasse hemicellulose hydrolysate at 38 degrees c in carbon-limited chemostat culture. the pretreatment of the acid hydrolysate prior to microbial cultivation consisted of partial neutralization with ammonia and sodium hydroxide, plus the addition of phosphorus, which was the only other growth-limiting nutrient apart from nitrogen. the cell yield coefficient on nitrogen was 16.78. the critical dilution rate was higher (0.35 h(-1)) in dilute ... | 1992 | 18601125 |
| isolation and identification of a candida digboiensis strain from an extreme acid mine drainage of the lignite mine, gujarat. | an extremely acidic mine drainage (amd) water sample was collected in 1998 and 2008 from panandhro lignite mine, gujarat, india. the yeast isolated from this sample was identified using mini api identification system, as a member of genus candida. the major cellular fatty acids detected by fame from the isolate are c(16:0) and c(18:2) (cis 9,12)/c(18:0alpha) as 25.23 and 19.5%, respectively. the isolate was identified as candida digboiensis by 18s rrna gene sequence analysis and designated as ca ... | 2009 | 19810040 |
| biosensor analyzer for bod index express control on the basis of the yeast microorganisms candida maltosa, candida blankii, and debaryomyces hansenii. | the parameters of biosensors based on the yeast strains candida maltosa vkm y-2359, candida blankii vkm y-2675, and debaryomyces hansenii vkm y-2482 for biochemical oxygen demand (bod) detection are compared. the catalytic activity of the strains was analyzed in relation to the growth phase. the possibility of using d. hansenii as a basis for receptor element of a biosensor for bod detection in municipal and biotechnological wastewaters was shown. | 2012 | 22418260 |
| description of groenewaldozyma gen. nov. for placement of candida auringiensis, candida salmanticensis and candida tartarivorans. | dna sequence analyses have demonstrated that species of the polyphyletic anamorphic ascomycete genus candida may be members of described teleomorphic genera, members of the candida tropicalis clade upon which the genus candida is circumscribed, or members of isolated clades that represent undescribed genera. from phylogenetic analysis of gene sequences from nuclear large subunit rrna, mitochondrial small subunit rrna and cytochrome oxidase ii, candida auringiensis (nrrl y-17674(t), cbs 6913(t)), ... | 2016 | 27142089 |
| relation between phylogeny and physiology in some ascomycetous yeasts. | the question of whether yeasts with similar physiological properties are closely related has been examined using recently published phylogenetic analyses of 26s domain d1/d2 rdna nucleotide sequences from all currently recognized ascomycetous yeasts. when apparently unique metabolic pathways are examined, some relationships between physiology and rdna phylogeny are evident. most candida and pichia species that are able to assimilate methanol as the sole carbon source are in a clade delimited by ... | 2003 | 12755482 |
