High-efficiency transformation of Saccharomyces cerevisiae cells by bacterial minicell protoplast fusion.

After a new transformation procedure, 10% of Saccharomyces cerevisiae cells were found to contain transforming DNA sequences. We used direct transfer of plasmid molecules by fusing bacterial minicell protoplasts to yeast protoplasts. Since the procedure significantly reduces the toxic effect of procaryotic protoplasm on the eucaryotic organism, it might be generally applicable in other systems ...

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. ...

Construction 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...

Transformation of Saccharomyces cerevisiae by electroporation.

A method for introducing heterologous DNA into Saccharomyces cerevisiae rapidly and efficiently by electroporation was developed. Transformant colonies appeared somewhat sooner than by the LiCl or spheroplast transformation method, and the time spent in manipulation was much less than for these two methods. The pores in the cell membrane formed by the high voltage of electroporation were reseal...
