Abstract

Strain 210417, which forms highly branched substrate and aerial mycelia, is a Gram-positive, aerobic and non-motile actinomycete isolated from mangrove rhizosphere soil. 16S rRNA gene sequence analysis showed that the strain should be classified in the genus , being most closely related to the type strains of (99.6 %) and (99.3 %). Chemotaxonomic properties [madurose as the major sugar in the cell wall; -diaminopimelic acid and -acetylmuramic acid in the peptidoglycan; MK-9(H) as the major menaquinone; iso-C (24.1 %) as major fatty acid; and phospholipid pattern type IV] are consistent with the assignment of strain 210417 to the genus . Strain 210417 could be differentiated from the closely related species and by morphological, physiological, biochemical and chemotaxonomic properties, 16S rRNA gene sequence analysis and DNA–DNA hybridization results. It is therefore proposed that strain 210417 represents a novel species of the genus , for which the name sp. nov. is given; the type strain is 210417 ( = CGMCC 4.5598  = DSM 45477).
