Abstract

A novel Gram-stain-positive actinobacterium, designated PS-14-7, was isolated from the rhizosphere of a mangrove on Pramuka Island, Indonesia, and its taxonomic position was investigated using a polyphasic approach. The peptidoglycan type of strain PS-14-7 was A4α and lysine was the diagnostic diamino acid of the peptidoglycan. The predominant menaquinone was MK-8(H) and the major fatty acids were anteiso-C, C and iso-C. The DNA G+C content was 72.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain PS-14-7 was closely related to Kis4-28 (99.6 %). However, DNA–DNA hybridization and phenotypic characteristics revealed that strain PS-14-7 differed from . Therefore, strain PS-14-7 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is PS-14-7 ( = NBRC 110108 = InaCC A 515). An emended description of the genus is also proposed.
