Abstract

Chemotaxonomic and morphological characterization of two actinomycete strains, MS1-3 and AS4-2, respectively isolated from moat sediment and scumming activated sludge, was carried out. This characterization clearly demonstrated that strains MS1-3 and AS4-2 belong to the genus . 16S rRNA gene sequencing studies showed that these isolates are most closely related to (98·1–98·3 % similarity), (97·9–98·0 %) and (97·8–97·9 %). However, the results of DNA–DNA hybridizations and physiological and biochemical tests showed that strains MS1-3 and AS4-2 could be differentiated from their closest phylogenetic relatives both genotypically and phenotypically. It is proposed that the two isolates be classified as representatives of a novel species of , sp. nov. The type strain is MS1-3 (=NBRC 100417=DSM 44801); AS4-2 (=NBRC 100418=DSM 44802) is a reference strain.
