Introduction of flocculation into industrial yeast, Saccharomyces cerevisiae saké, by protoplast fusion.
Protoplast fusion was applied to obtain intraspecific fusion in yeast strains in order to overcome restrictions imposed by the natural mating system. Acriflavine was used to construct petite mutants from non-flocculent industrial Saccharomyces cerevisiae saké strain. UV radiation was used to construct ura- mutants from a respiratory competent and highly flocculent S. cerevisiae NCYC869 strain. ...
متن کاملImprovement of a Wine Saccharomyces cerevisiae Strain by a Breeding Program.
Hybridization by spore conjugation was used to develop new and improved wine yeasts of Saccharomyces cerevisiae. The procedure was achieved with diploid, homothallic strains with high sporulation frequency and high spore viability. The method was verified by crossing flocculent and non-H(2)S-forming strains. Single-spore descendants of the hybrids were studied by tetrad analysis with regard to ...
متن کاملBehaviour of Kloeckera apiculata Flocculent Strain in Coculture with Saccharomyces cerevisiae
The behaviour of the flocculent Kloeckera apiculata strain in coculture with the nonflocculent Saccharomyces cerevisiae strain, both yeasts isolated from wine, has been analyzed. Pure culture of Kloeckera apiculata (apiculate yeast) exhibits 75 % flocculation in the yeast extract/peptone/glucose (containing 20 g/L of glucose, YPG20) medium after 24-hour incubation at 28 °C. This yeast expresses...
متن کاملPurification and partial characterization of a flocculin from brewer's yeast.
Analysis of a shear supernatant from flocculent, "fimbriated" Saccharomyces cerevisiae brewer's yeast cells revealed the presence of a protein involved in flocculation of the yeast cells and therefore designated a flocculin. The molecular mass of the flocculin was estimated to be over 300 kDa, as judged from sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Gel permeation chromatograph...
متن کاملConstruction of High Ethanol Fermenting Halotolerant Hybrid by Intergeneric Protoplast Fusion of Saccharomyces cerevisiae and Zygosaccharomyces rouxii
Saccharomyces cerevisiae M30, a high ethanol producing flocculent strain, was hybridized with Zygosaccharomyces rouxii TISTR1750, a halotolerant non-flocculent strain, by polyethylene glycol induced protoplast fusion. The protoplast fusion of these two yeast genera occurred with frequency of 5.89X10-5. Three fusants, namely RM11, RM37 and RM58, were selected based on their high ethanol fermenta...
