Abstract

The taxonomic position of two actinomycete strains, LC2 and LC11, isolated from a filtration substrate made from Japanese volcanic soil, was determined using a polyphasic approach. The strains grew at temperatures from 5 to 45 °C, on media of pH between 6 and 11 and in the presence of 7 % NaCl. The major menaquinone was MK-9(H). The major fatty acid was iso-C. A phylogenetic tree based on 16S rRNA gene sequences showed that the two strains formed a distinct evolutionary lineage within the genus . On the basis of their morphological, physiological and genotypic characteristics, the isolates are proposed to represent two novel species of the genus , for which the names sp. nov. (type strain LC2 =IAM 15387 =CCTCC AB206019), and sp. nov. (type strain LC11 =IAM 15388 =CCTCC AB206020) are proposed.
