Algoriphagus yeomjeoni sp. nov., isolated from a marine solar saltern in the Yellow Sea, Korea.
Two Gram-negative, rod-shaped bacterial strains, MSS-160(T) 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 25-30 degrees C. Strains MSS-160(T) and MSS-161 contained MK-7 as the predominant menaquinone and large amounts of fatty acids C(16 : 1)omega7c and/or iso-C(15 : 0) 2-OH and iso-C(15 : 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-160(T) and MSS-161 exhibited no difference in their 16S rRNA gene sequences and possessed a mean DNA-DNA relatedness level of 91 %; they exhibited 16S rRNA similarity levels of 96.6-99.3 % to the type strains of Algoriphagus species with validly published names. DNA-DNA 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-160(T) 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-160(T)=KCTC 12309(T)=JCM 12598(T)) is proposed.
