Interspecific hybrids are commonplace in agriculture and horticulture; bread wheat and grapefruit are but two examples. The benefits derived from interspecific hybridisation include the potential of generating advantageous transgressive phenotypes. This paper describes the generation of a new breed of wine yeast by interspecific hybridisation between a commercial Saccharomyces cerevisiae wine y...

The metabolism of ferulic acid (FA) was studied during fermentation with different species and strains lactic bacteria (LAB) yeasts, in synthetic sourdough medium. Yeast Kazachstania humilis, bulderi, Saccharomyces cerevisiae, as well Fructilactobacillus sanfranciscensis, Lactiplantibacillus plantarum, xiangfangensis, Levilactobacillus hammesii, Latilactobacillus curvatus sakei were selected fr...

there is a great call for using microbial bio-decaffeination approach to remove caffeinefrom caffeinated products and industrial wastes. we aimed in this study to screen strainsof yeasts which exhibit high caffeine tolerance and to investigate the bio-degradation ofcaffeine under growth conditions. sixteen yeast strains were isolated from the cultivatedtea soils collected from sites of northern...

Alcoholic fermentation is a polimicrobial process involving a large number of genera and species of yeast and bacteria. Th e major yeast genera involved in this process belongs to the Saccharomyces spp. Th e aim of this study was the isolation, identifi cation and determination of genetic diversity of indigenous Saccharomyces cerevisiae natural population taken from cv. Plavac mali from seclude...

This study aimed to isolate the endophytic fungi of soursop leaves that have potential as anti-yeast. Soursop were collected from 3 locations in West Java, Indonesia. The secondary metabolites produced by extracted with ethyl acetate and tested for anti-yeast activity against Saccharomyces cerevisiae Candida tropicalis. Profile extracts contents characterization was carried out using thin-layer...

The yield of fermentation process, bioethanol, is one the important product obtained from renewable energy sources. Yeasts are commonly used in ethanol production due to their high tolerance, productivity, and ability ferment different kinds simple sugars. Saccharomyces cerevisiae yeast species most industrial production. Therefore, isolation identification new strains with capacity very for bi...

the hepatitis b surface antigen ( hbsag) gene was isolated from an iranian hbeag positive carrier by pcr. the gene was cloned in puc19 for sequencing and pyes2 for expression in saccharomyces cerevisiae, which pnf1 and pdf3 constructs were made respectively. the sequencing data showed that the isolated hbsag gene shared more than 90% homology with the ayw subtype. the pdf3 was transferred into ...

During 3 years, we explored the biodiversity of indigenous yeast flora in five Greek wine regions by collecting varietal grape samples, conventionally and biologically cultured. Spontaneous fermentations were carried out native microbiota juice, without inoculation selected industrially produced yeast. The flora, isolated at three phases these fermentations, was purified characterized using dif...

-A feeding trial was conducted in eight cows to compare the effect of supplementing commercial yeast species Saccharomyces cerevisiae and Saccharomyces siccum on milk yield and its composition. Cows were randomly assigned to one of the two treatment groups consisting four animals each. Commecial yeast granules were added at the rate of 25 g /cow / day to the concentrate feed in the afternoon fo...

Yeast researchers need model systems for ecology and evolution, but the model yeast Saccharomyces cerevisiae is not ideal because its evolution has been affected by domestication. Instead, ecologists and evolutionary biologists are focusing on close relatives of S. cerevisiae, the seven species in the genus Saccharomyces. The best-studied Saccharomyces yeast, after S. cerevisiae, is S. paradoxu...
