Strains: 1, strain TG409T; 2, Arenibacter palladensis LMG 21972T; 3, Arenibacter troitsensis KCTC 12362T; 4, Arenibacter echinorum KCTC 22013T. Identities of strains and references are as in Table 3. Components that represented <0.1% in all strains are not included.
In strain 1, the double-bond position of iso-C17:1 was not determined; in strains 2 to 4, this fatty acid was reported as iso-C17:1 ω9c.
Fatty acid composition contributed also by iso-C15:0 2-OH.
Summed feature 1 values represent fatty acids that could not be separated by gas-liquid chromatography with the MIDI system for strains LMG 21972T, KCTC 12362T, and KCTC 22013T. This feature consists of iso-C15:0 2-OH, C16:1 ω7c, and C16:1 ω7t.
