Molecular analysis of artisanal Italian cheeses reveals Enterococcus italicus sp. nov. / M.G. Fortina, G. Ricci, D. Mora, P.L. Manachini. - In: INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY. - ISSN 1466-5026. - 54:Part. 5(2004), pp. 1717-1721.
Abstract:
The taxonomic positions of seven atypical Enterococcus strains, isolated from artisanal Italian
cheeses, were investigated in a polyphasic study. By using 16S rRNA gene sequencing,
DNA–DNA hybridization and intergenic transcribed spacer analysis, as well as by examining the
phenotypic properties, the novel isolates were shown to constitute a novel enterococcal species.
Their closest relatives are Enterococcus sulfureus and Enterococcus saccharolyticus, having a
16S rRNA gene sequence similarity of 96?7%. This group of strains can be easily differentiated
from the other Enterococcus species by DNA–DNA hybridization and by their phenotypic
characteristics: the strains do not grow in 6?5% NaCl, and they do not produce acid from
L-arabinose, melezitose, melibiose, raffinose or ribose. The name Enterococcus italicus sp. nov.
is proposed for this species, with strain DSM 15952T (=LMG 22039T) as the type strain.
