titleOfInvention |
Method of producing yeast mutants and the use thereof |
abstract |
The present invention relates to a method of producing yeast mutants, to yeast mutants and the use thereof. In order to provide yeasts which, at a given sugar content, produce a low ethanol content and a relatively high glycerol content in ethanolic fermentation and which are simultaneously obtainable rapidly, it is proposed in accordance with the invention that at least one yeast strain be contacted in a first mutagenesis step with a first mutagen and in a second mutagenesis step with a second mutagen, the first and second mutagens being different from one another and being selected from the following groups: nucleotide-alkylating agent, nucleotide-deaminating agent and UV radiation, and a first selection step being executed between the first and second mutagenesis steps and a second selection step being executed after the second mutagenesis step, in which the mutants that originate from the prior mutagenesis step in each case are exposed to a selection factor selected from the following groups: (a) hypertonic medium and (b) alcohol dehydrogenase inhibitor. |
