| occurrence and dominance of yeast species in naturally fermented milk from the tibetan plateau of china. | to determine which yeasts are present in the naturally fermented milks of china, 69 samples made by the nomads of tibet were collected from the tibetan plateau in china. from these samples, 225 strains of yeast were isolated and identified using conventional microbiological analysis and gene sequencing analysis of the d1/d2 domain of the large subunit (26s) ribosomal dna. the results showed that the total concentration of yeasts in these samples ranged from 5.01 to 8.97 log10 colony-forming unit ... | 2010 | 20921981 |
| the ability of a cold-adapted rhodotorula mucilaginosa strain from tibet to control blue mold in pear fruit. | cold-adapted yeasts were isolated from soil samples collected in tibet and evaluated as potential biocontrol agents against blue mold (penicillium expansum) of pear fruit in cold storage. yc1, an isolate identified as rhodotorula mucilaginosa, was found to exhibit the greatest biocontrol activity among the different isolates that were screened. a washed cell suspension of yc1 exhibited the best biocontrol activity among three different preparations that were used in the current study. a concentr ... | 2015 | 26454432 |
| evaluation of yeasts from tibetan fermented products as agents for biocontrol of blue mold of nashi pear fruits. | a total of 20 strains of yeast isolated from tibetan fermented products were screened for antagonism against blue mold of pear caused by penicillium expansum. six isolates that inhibited incidence of postharvest decay by 35% or more were selected for further screening. among them, the most effective was rhodotorula mucilaginosa. the results showed that washed cell suspensions of r. mucilaginosa yielded better antagonistic efficacy than unwashed cell-culture mixtures, cell-free culture filtrates, ... | 2015 | 25845361 |
