A Gram-positive and catalase-negative coccus that formed chains, strain FP15-1T, isolated from fermented tea leaves (miang), was studied systematically. The strain was facultatively anaerobic and produced L-lactic acid from glucose. Demethylmenaquinone (DMK-7) was the major menaquinone. Straight-chain unsaturated fatty acids C16 : 1 and C18 : 1 were the dominant components. The DNA G+C content was 37.8 mol%. On the basis of 16S rRNA and RNA polymerase
subunit (rpoA) gene sequence analysis, strain FP15-1T was closely related to Enterococcus italicus KCTC 5373T, with 99.2 and 93.8 % similarity, respectively. The strain could be clearly distinguished from E. italicus ATCC 5373T by low DNA–DNA relatedness (
33.8 %) and phenotypic characteristics. Therefore, this strain represent a novel species of the genus Enterococcus, for which the name Enterococcus camelliae sp. nov. is proposed. The type strain is FP15-1T (=KCTC 13133T =NBRC 101868T =NRIC 0105T =TISTR 932T =PCU 277T).
The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA and rpoA gene sequences of strain FP15-1T are respectively EF154454 and EF197993.
16S rRNA gene sequence-based maximum-likelihood and maximum-parsimony trees are available as supplementary material with the online version of this paper.
