Nine agar-degrading strains, designated JAMB A3, JAMB A7, JAMB A24, JAMB A33, JAMB A94, JAMM 0654, JAMM 0793, JAMM 1327 and JAMM 1340, were isolated from deep-sea sediment in Suruga Bay and Sagami Bay and off Kagoshima, Japan. On the basis of 16S rRNA gene sequence analysis, the strains were found to be closely affiliated with members of the genera and . The hybridization values for DNA–DNA relatedness between two of these strains and reference strains were significantly lower than that accepted as the phylogenetic definition of a species. On the basis of their distinct taxonomic characteristics, six of the isolated strains represent two novel species of the genus , for which the names sp. nov. (type strain JAMB A3 =JCM 14708 =DSM 19200) and sp. nov. (type strain JAMB A94 =JCM 14709 =DSM 19189) are proposed.
