Oenococcus sicerae sp. nov., isolated from French cider.

Two Gram-stain-positive, small ellipsoidal cocci, non-motile, oxidase- and catalase-negative, and facultative anaerobic strains (UCMA15228T and UCMA17102) were isolated in France, from fermented apple juices (ciders). The 16S rRNA gene sequence was identical between the two isolates and showed 97 % similarity with respect to the closest related species Oenococcus oeni and O. kitaharae. Therefore, the two isolates were classified within the genus Oenococcus. The phylogeny based on the pheS gene sequences also confirmed the position of the new taxon. DNA-DNA hybridizations based on in silico genome-to-genome comparisons (GGDC) and Average Nucleotide Identity (ANI) values, as well as species-specific PCR, validated…
