Differentiation of Tetragenococcus populations occurring in products and manufacturing processes of puffer fish ovaries fermented with rice-bran

Tetragenococcus strains isolated from the manufacturing process of Japanese puffer fish ovaries fermented with rice-bran were characterized and differentiated phenotypically and genotypically. A total of 413 Tetragenococcus isolates were evaluated. On the basis of five representative substrates, the...

Description
Summary:	Tetragenococcus strains isolated from the manufacturing process of Japanese puffer fish ovaries fermented with rice-bran were characterized and differentiated phenotypically and genotypically. A total of 413 Tetragenococcus isolates were evaluated. On the basis of five representative substrates, the isolates were grouped into seven groups. An RFLP (restriction fragment length polymorphisms) analysis of the 16S rRNA gene of representative strains of major groups revealed that they could be grouped into two groups: one was identified as the most prominent halophilic lactic acid coccus, Tetragenococcus halophilus, and the other as T. muriaticus, which has recently been added to the genus Tetragenococcus as a new species. Physiologically, the major differences between the two groups were found in the ability to grow in medium not supplemented with NaCl and the fermentation of l-arabinose, sucrose and d-mannitol, and several other carbohydrates.
