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.

UI	MeSH Term	Description	Entries
D007934	Leuconostoc	A genus of gram-positive, facultatively anaerobic bacteria whose growth is dependent on the presence of a fermentable carbohydrate. It is nonpathogenic to plants and animals, including humans.	Leukonostoc
D008242	Lysogeny	The phenomenon by which a temperate phage incorporates itself into the DNA of a bacterial host, establishing a kind of symbiotic relation between PROPHAGE and bacterium which results in the perpetuation of the prophage in all the descendants of the bacterium. Upon induction (VIRUS ACTIVATION) by various agents, such as ultraviolet radiation, the phage is released, which then becomes virulent and lyses the bacterium.

D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
D006095	Gram-Positive Cocci	Coccus-shaped bacteria that retain the crystal violet stain when treated by Gram's method.	Gram Positive Cocci
D001435	Bacteriophages	Viruses whose hosts are bacterial cells.	Phages,Bacteriophage,Phage
D014920	Wine	Fermented juice of fresh grapes or of other fruit or plant products used as a beverage.	Wines
D016685	Mitomycin	An antineoplastic antibiotic produced by Streptomyces caespitosus. It is one of the bi- or tri-functional ALKYLATING AGENTS causing cross-linking of DNA and inhibition of DNA synthesis.
