A procedure is described whereby the cytoplasmically‐inherited killer character of a laboratory strain of Saccharomyces cerevisiae is transferred to a brewing yeast strain. Neither preparation of protoplasts of the brewing yeast nor mutation of its nuclear genes are required for this process. The brewing yeast killer strains produced have the advantages over their parent brewing cell that they kill sensitive yeasts and are immune to the killing action of certain killer yeasts. The method described offers significant advantages over the process of transformation as a means of genetically manipulating commercial yeasts.
