sp. nov., an acid-tolerant actinobacterium isolated from bio-fertilizer of species.

A novel acid-tolerant actinobacterium (strain LPG 2), which formed fragmented substrate mycelia, was isolated from bio-fertiliser of spp. collected from Lampang Province, Thailand. Its morphological and chemotaxonomic properties, e.g., the presence of mycolic acid and MK-8 (H) in the cells, showed that strain LPG 2 was a member of the genus . 16S rRNA gene sequence analysis revealed that this strain was closely related to NBRC 14405 (98.7 %). The low average nucleotide identity-blast and digital DNA-DNA hybridization values (<78.6 and <24.0 %, respectively), and several phenotypic differences between strain LPG 2 and its related type strains, indicated that the strain merits classification as representing a novel species of the genus , for which we propose the name sp. nov. The type strain is LPG 2 (=TBRC 11242=NBRC 114293).
