Abstract: The invention relates to an enzyme product comprising a beta-galactosidase product. The invention provides that the beta-galactosidase product has an inactive arylsulphatase.

Abstract: A method of producing 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, at least one yeast strain is 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 are different from one another and are selected from the following groups: nucleotide-alkylating agent, nucleotide-deaminating agent, and UV radiation. The method further includes a first selection step 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.

Abstract: The present invention relates to a method of producing a peptide consisting of the amino acids 63 to 110 of dermcidin (SEQ ID NO: 3) comprising (a) culturing a host cell carrying a nucleic acid molecule encoding the peptide in an expressible form, and (b) optionally isolating the peptide from the culture. Furthermore, the invention relates to a nucleic acid molecule encoding a fusion protein comprising or consisting of (a) a peptide heterologous with regard to dermcidin protein-tag; and, C-terminally thereof (b) a peptide having the antimicrobial activity of dermcidin wherein the fusion protein contains an arginine residue located immediately N-terminally of the peptide of (b).
