Abstract

Three Gram-positive, NaCl-requiring actinobacteria were isolated from a marine sponge, sp., collected from the coast of Tateyama City, Japan. Comparison of 16S rRNA gene sequences indicated that these strains represent novel members of the genus , exhibiting low 16S rRNA gene sequence similarities of 98.3–97.4 % with recognized members of the genus. The cell hydrolysates contained the LL-isomer of diaminopimelic acid and the predominant quinones were MK-9 (H and/or H). The DNA G+C contents were in the range 72–75 mol%. A polyphasic study of the strains and comparison of the characters with related species of the genus show that these strains represent three novel species of the genus . Therefore, the names sp. nov., sp. nov. and sp. nov. are proposed for strains Sp080513SC-30 (=NBRC 105048 =DSM 41969), Sp080513SC-31 (=NBRC 105049 =DSM 41970) and Sp080513GE-26 (=NBRC 105047 =DSM 41968), respectively.
