Abstract

Two yellow-pigmented, Gram-reaction-negative strains, designated 01SU5-P and 03SU3-P, were isolated from the freshwater of Woopo wetland, Republic of Korea. Both strains were aerobic, non-motile and catalase-negative. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the two isolates belong to the genus , showing the highest level of sequence similarity with respect to W-50 (95.4–95.7 %). The two novel isolates shared 99.4 % sequence similarity. DNA–DNA hybridization between the isolates and the type strain of clearly suggested that strains 01SU5-P and 03SU3-P represent two separate novel species in the genus . The two strains displayed different fingerprints after PCR analysis using the repetitive primers BOX, ERIC and REP. Several phenotypic characteristics served to differentiate these two isolates from recognized members of the genus . The data from the polyphasic study presented here indicated that strains 01SU5-P and 03SU3-P should be classified as representing novel species in the genus , for which the names sp. nov. and sp. nov., respectively, are proposed. The type strain of sp. nov. is 01SU5-P ( = KCTC 23326 = JCM 17509) and the type strain of sp. nov. is 03SU3-P ( = KCTC 23340 = JCM 17547).
