Various strains, including some killer strain and respiratory-deficientmutants of Saccharomyces cerevisiae were enucleated after treatment withcytochalasin B.Removal of nuclei from protruding sphaeroplasts was induced bycentrifugation in a Percoll density gradient. The enucleation yield (which averaged about 80%) and the quality of the cytoplasts were best when the yeast culture had been synchronized with nocodazole before the preparation. The presence of 1 mM CaCU and ATP (10 pM) in the enucleation medium prevented theformation of fragile products or aggregation. Cytoplasts could be stored for atleast 1 day without visible deterioration.}, type={Text}, title={Classic techniques for improvement of industrial yeast strains: Part III - A method for enucleation of Saccharomyces sp.}, URL={http://rcin.org.pl/Content/138414/PDF/POZN271_173779_biotechnologia-2002-no2-salek.pdf}, keywords={biotechnology}, }
