title: Serinibacter tropicus sp. nov., an actinobacterium isolated from the rhizosphere of a mangrove, and emended description of the genus Serinibacter.
abstract: A novel Gram-stain-positive actinobacterium, designated PS-14-7(T), 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(T) was A4α and lysine was the diagnostic diamino acid of the peptidoglycan. The predominant menaquinone was MK-8(H4) and the major fatty acids were anteiso-C(15 : 0), C(16 : 0) and iso-C(16 : 0). The DNA G+C content was 72.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain PS-14-7(T) was closely related to Serinibacter salmoneus Kis4-28(T) (99.6%). However, DNA-DNA hybridization and phenotypic characteristics revealed that strain PS-14-7(T) differed from Serinibacter salmoneus . Therefore, strain PS-14-7(T) represents a novel species of the genus Serinibacter , for which the name Serinibacter tropicus sp. nov. is proposed. The type strain is PS-14-7(T) ( = NBRC 110108(T) = InaCC A 515(T)). An emended description of the genus Serinibacter is also proposed.
