The antibacterial activity of tylosin, an antibiotic produced by Streptomyces fradiae, was investigated using both typical culture strains and newly isolated strains of Hiochi-bacteria belonging to the group of lactic acid bacteria. The growth of all strains tested was completely inhibited at 30℃ for 30 days or more with tylosin at a very low concentration (5〜40μg/ml).Desmycosin, a derivative of tylosin, also exhibited antibacterial activity as effective as that of tylosin against Hiochi-bacteria.The antibacterial activity of tylosin on Hiochi-bacteria was affected by both alcohol concentration and the pH of sake and also by additions of polypeptone, yeast extract and other nutrients to sake.Making comparisons between the antibacterial activity and other characteristics of tylosin and those of other preservatives such as n-heptyl or octyl ester of p-hydroxybenzoic acid, ethyl-α-ethanolamino-β-benzoylpropionate, egg white lysozyme, the author considers that tylosin may be a promising preservative for sake.
