TETRAGENOCOCCUS MURIATICUS SP-NOV, A NEW MODERATELY HALOPHILIC LACTIC-ACID BACTERIUM ISOLATED FROM FERMENTED SQUID LIVER SAUCE

A total of 11 strains of moderately halophilic histamine-producing bac teria isolated from fermented squid liver sauce were studied phenotypi cally, genotypically, and phylogenetically, These strains are consider ed members of the genus Tetragenococcus based on their physiological, morphological, and chemotaxonomic characteristics. A 16S rRNA gene seq uence analysis showed that these strains clustered with, but were sepa rate from, Tetragenococcus halophilus. The results of DNA-DNB hybridiz ation experiments indicated that the new isolates represent a new Tetr agenococcus species, for which we propose the name Tetragenococcus mur iaticus; strain X-1 (= JCM 10006) is the type strain of this species.
