A Gram-reaction-positive, endospore-forming bacterium, designated strain P1
, was isolated from water samples collected from Pasinler Hot Spring and characterized using a polyphasic approach to clarify its taxonomic position. Strain P1
was found to have chemotaxonomic and morphological characteristics consistent with its classification in the genus
. The strain shared the highest 16S rRNA gene sequence identity values with
R-6488
(97.6 %) and
MO-04
(97.2 %) and formed a distinct clade with both type strains in the phylogenetic trees based on 16S rRNA gene sequences. Strain P1
could grow optimally at 55 °C and in the presence of 2 % NaCl. The organism was found to contain meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan. The major polar lipids were diphosphatidylglycerol and phosphatidylglycerol. The predominant menaquinone was determined to be MK-7. The major cellular fatty acids were identified as iso-C
, iso-C
and anteiso-C
. Based upon the consensus of phenotypic and phylogenetic analyses, strain P1
represents a novel species of the genus
, for which the name
sp. nov. is proposed. The type strain is P1
(=DSM 107529
=CECT 9885

).
