Abstract

Two novel aerobic, dark-orange-pigmented, Gram-negative bacterial strains, designated KMM 3531 and KMM 3953, were isolated from the green alga . Analysis of the 16S rRNA gene sequences showed that the strains represented a novel lineage within the family . The most closely related genera with validly published names were , , , , and , with 16S rRNA gene sequence similarities of 93.3–91.8 %. Cells of strains KMM 3531 and KMM 3953 were rod-shaped, motile by gliding and grew at temperatures up to 49 °C. They produced acid from carbohydrates and possessed oxidase, catalase, -galactosidase and agarase activities. The predominant cellular fatty acids were iso-C iso-C 3-OH, iso-C G, summed feature 3 (comprising C 7 and/or iso-С 2-OH), iso-C 9 and iso-C 3-OH. The DNA G+C content was 47–49 mol%. On the basis of phenotypic and genotypic characteristics, strains KMM 3531 and KMM 3953 represent a novel genus and species, for which the name gen. nov., sp. nov. is proposed. The type strain is KMM 3531 (=DSM 19858=JCM 11733=KCTC 22016).
