Abstract
Two Gram-negative, rod-shaped bacterial strains, MSS-160T and MSS-161, were isolated from a marine solar saltern in the Yellow Sea, Korea, and subjected to a polyphasic taxonomic study. The two strains grew optimally in the presence of 2 % (w/v) NaCl and at 2530 °C. Strains MSS-160T and MSS-161 contained MK-7 as the predominant menaquinone and large amounts of fatty acids C16 : 1ω7c and/or iso-C15 : 0 2-OH and iso-C15 : 0. The DNA G+C content of the two strains was 41 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that the two strains were phylogenetically affiliated to the genus Algoriphagus. Strains MSS-160T and MSS-161 exhibited no difference in their 16S rRNA gene sequences and possessed a mean DNADNA relatedness level of 91 %; they exhibited 16S rRNA similarity levels of 96·699·3 % to the type strains of Algoriphagus species with validly published names. DNADNA relatedness levels between the two strains and the type strains of five Algoriphagus species were lower than 46 %. On the basis of phenotypic, phylogenetic and genetic data, strains MSS-160T and MSS-161 were classified in the genus Algoriphagus as members of a novel species, for which the name Algoriphagus yeomjeoni sp. nov. (type strain, MSS-160T=KCTC 12309T=JCM 12598T) is proposed.
