Abstract
A novel, extremely halophilic archaeon B3T was isolated from shrimp-salted seafood. Its morphology, physiology, biochemical features and 16S rRNA gene sequence were characterized. Strain B3T is non-motile, Gram-variable, requires at least 10% (w/v) NaCl for growth and grows in the ranges of 21-50 °C and pH 6.5-9.0. The DNA G + C content of strain B3T was 63.2 mol%. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that strain B3T belonged to the genus Halalkalicoccus and was phylogenetically closely related to the type strain Halalkalicoccus tibetensis (98.64%). However, DNA-DNA hybridization experiments showed 7.0% relatedness between strain B3T and a strain of a reference species of the genus Halalkalicoccus. Combined analysis of 16S rRNA gene sequences, DNA-DNA relatedness data, physiological and biochemical tests indicated that the genotypic and phenotypic characteristics differentiate strain B3T from other Halalkalicoccus species. On the basis of the evidence presented in this report, strain B3T represents a novel species of the genus Halalkalicoccus, for which the name Halalkalicoccus jeotgali. sp. nov. is proposed. The type strain is B3T (=KCTC 4019T =DSM 18796T=JCM 14584T= CECT 7217T.
