Winogradskyella algae sp. nov., a marine bacterium isolated from the brown alga
- 28 Downloads
An aerobic, Gram-negative, yellow-pigmented non-motile rod-shaped bacterium Kr9-9T was isolated from a brown alga specimen collected near the Kuril Islands. Based on the 16S rRNA gene sequence analysis strain Kr9-9T was assigned to the genus Winogradskyella, and its close phylogenetic neighbors were found to be Winogradskyella damuponensis KCTC 23552T, Winogradskyella sediminis LMG 28075T, and Winogradskyella rapida CCUG 59098T showing high similarities of 98.1%, 97.5%, and 97.1%, respectively. It contained MK-6 as the predominant menaquinone and iso-C15:0, anteiso-C15:0, iso-C16:0 3-OH followed by iso-C15:1 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 Kr9-9T 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 Kr9-9T (= KMM 8180T = KACC 19709T).
