Characterization of strictly lytic phages infecting Oenococcus oeni from Merlot wines and proposal of a new genus

Yasma Barchi, Florencia Oviedo-Hernandez, Amel Chaïb, Cécile Philippe et autres

ABSTRACT Oenococcus oeni is the predominant lactic acid bacteria species in wine, where it performs the malolactic fermentation, which helps to secure and preserve wine quality. Here, we describe the morphological, biological, and genomic characterization of siphophage Krappator X 27 , a …

Phage Encounters Recorded in CRISPR Arrays in the Genus Oenococcus

Yasma Barchi, Cécile Philippe, Amel Chaïb, Florencia Oviedo-Hernandez et autres

The Oenococcus genus comprises four recognized species, and members have been found in different types of beverages, including wine, kefir, cider and kombucha. In this work, we implemented two complementary strategies to assess whether oenococcal hosts of different species and habitats were …
