Winogradskyella algae sp. nov., a marine bacterium isolated from the brown alga

An aerobic, Gram-negative, yellow-pigmented non-motile rod-shaped bacterium Kr9-9 T was isolated from a brown alga specimen collected near the Kuril Islands. Based on the 16S rRNA gene sequence analysis strain Kr9-9 T was assigned to the genus Winogradskyella, and its close phylogenetic neighbors we...

Description
Summary:An aerobic, Gram-negative, yellow-pigmented non-motile rod-shaped bacterium Kr9-9 T was isolated from a brown alga specimen collected near the Kuril Islands. Based on the 16S rRNA gene sequence analysis strain Kr9-9 T was assigned to the genus Winogradskyella, and its close phylogenetic neighbors were found to be Winogradskyella damuponensis KCTC 23552 T , Winogradskyella sediminis LMG 28075 T , and Winogradskyella rapida CCUG 59098 T showing high similarities of 98.1%, 97.5%, and 97.1%, respectively. It contained MK-6 as the predominant menaquinone and iso-C 15:0 , anteiso-C 15:0 , iso-C 16:0 3-OH followed by iso-C 15:1 as the major fatty acids. Polar lipids included phosphatidylethanolamine, three unidentified aminolipids and an unidentified lipid. The DNA C+C content was 32.3 mol%. Based on the phylogenetic analysis and distinctive phenotypic characteristics, strain Kr9-9 T is concluded to represent a novel species of the genus Winogradskyella , for which the name Winogradskyella algae sp. nov. is proposed. The type strain of the species is strain Kr9-9 T (= KMM 8180 T  = KACC 19709 T ).
