title: Lysogeny of Oenococcus oeni (syn. Leuconostoc oenos) and study of their induced bacteriophages.
abstract: A large number of strains of Oenococcus oeni (formerly Leuconostoc oenos) that had been isolated from wines were checked for lysogeny with mitomycin C as inducer. As a result of this test, 45% of the strains proved to be lysogenic, suggesting that lysogeny is widespread among bacteria isolated from wines during malolactic fermentation. The sensitivity of bacteria to phages was very different, depending on the strain. All the lysogenic strains were resistant to infection by the temperate phage they released. Some phages infected none of the strains. Phages of Oenoc. oeni had a classical morphology, an isometric head, and a long striated tail. With the broadest host strain as an indicator, phages were detected in wines after malolactic fermentation.
