Algoriphagus terrigena sp. nov., isolated from soil.

A Gram-negative, non-motile, non-spore-forming bacterial strain, DS-44T, was isolated from soil from Dokdo in Korea, and its taxonomic position was investigated by using a polyphasic approach. It grew optimally at 25 degrees C and in the presence of 2 % (w/v) NaCl. Strain DS-44T contained MK-7 as the predominant menaquinone and iso-C(15 : 0) and C(16 : 1)omega7c and/or iso-C(15 : 0) 2-OH as the major fatty acids. The DNA G+C content was 49.0 mol%. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain DS-44T belongs to the genus Algoriphagus of the phylum Bacteroidetes. Similarity values between the 16S rRNA gene sequences of strain DS-44T and those of the type strains of recognized Algoriphagus species were in the range 93.8-95.7 %, making it possible to categorize strain DS-44T as a species that is separate from previously described Algoriphagus species. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain DS-44T (=KCTC 12545T = CIP 108837T) was classified in the genus Algoriphagus as the type strain of a novel species, for which the name Algoriphagus terrigena sp. nov. is proposed.
