Abstract

A novel Gram-stain-positive actinobacterium, designated H25-14, was isolated from a sea sediment sample, and its taxonomic position was investigated by a polyphasic approach. The peptidoglycan type of strain H25-14 was A4α and lysine was the diagnostic diamino acid of the peptidoglycan. The predominant menaquinone was MK-9(H) and the major fatty acids were anteiso-C and iso-C. The DNA G+C content was 73.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain H25-14 was closely related to NBRC 104352 (98.3 %). However, DNA–DNA hybridization data and phenotypic characteristics revealed that strain H25-14 differed from NBRC 104352. Therefore, strain H25-14 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is H25-14 ( = NBRC 108565 = DSM 25477). An emended description of the genus is also proposed.
