| characterization of new types of mannosylerythritol lipids as biosurfactants produced from soybean oil by a basidiomycetous yeast, pseudozyma shanxiensis. | mannosylerythritol lipids (mels) are glycolipid biosurfactants produced by the yeast strains of the genus pseudozyma. these show not only the excellent surface-active properties but also versatile biochemical actions. in course of mel production from soybean oil by p. shanxiensis, new extracellular glycolipids (more hydrophilic than the previously reported mels) were found in the culture medium. as a result of the structural characterization, the glycolipids were identified as a mixture of 4-o-[ ... | 2007 | 17898510 |
| identification of ustilago cynodontis as a new producer of glycolipid biosurfactants, mannosylerythritol lipids, based on ribosomal dna sequences. | mannosylerythritol lipids (mels) are one of the most promising glycolipid biosurfactants known because of their multifunctionality and biocompatibility. the search for novel producers of mels was undertaken based on the analysis of ribosomal dna sequences on basidiomycetous yeasts. the bermuda grass smut fungus ustilago cynodontis nbrc 7530, which taxonomically relates to pseudozyma shanxiensis known as a mel-c producer, was found to accumulate glycolipids in the cultured medium. under a shake f ... | 2008 | 18781055 |
| pseudozyma hubeiensis sp. nov. and pseudozyma shanxiensis sp. nov., novel ustilaginomycetous anamorphic yeast species from plant leaves. | among basidiomycetous yeast strains isolated from wilting leaves of various plants in china, two groups of pseudozyma strains were distinguished from the others by morphological and physiological characterization. molecular taxonomic analysis based on sequencing of the large subunit (26s) rrna gene d1/d2 domain and internal transcribed spacer (its) region confirmed that the two groups represent two novel species. they are proposed as pseudozyma hubeiensis sp. nov. (type strain ws 6.4t = as 2.249 ... | 2006 | 16403900 |
| the assessment of epiphytic yeast diversity in sugarcane phyllosphere in thailand by culture-independent method. | the diversity of epiphytic yeasts from sugarcane (saccharum officinarum linn.) phyllospheres in thailand was investigated by culture-independent method based on the analysis of the d1/d2 domains of the large subunit rrna gene sequences. forty-five samples of sugarcane leaf were collected randomly from ten provinces in thailand. a total of 1342 clones were obtained from 45 clone libraries. 426 clones (31.7 %) were closely related to yeast strains in the genbank database, and they were clustered i ... | 2015 | 26615738 |
| production of glycolipid biosurfactants, mannosylerythritol lipids, by pseudozyma siamensis cbs 9960 and their interfacial properties. | the search for a novel producer of glycolipid biosurfactants, mannosylerythritol lipids (mels), was undertaken on the basis of the analysis of ribosomal dna sequences of yeast strains of the genus pseudozyma. in the course of the investigation, pseudozyma siamensis cbs 9960, which is closely related to pseudozyma shanxiensis, a known mel-c producer but with a different morphology, was found to accumulate a large amount of glycolipids. on thin layer chromatography, the extracellular glycolipids s ... | 2008 | 18558340 |
