Cellular fatty acid composition (%) of R1DC9T (grown in LB+FSW) and closely related members (generally, grown in marine broth; growth medium specifications in the reference articles in the note) of Cytophagales
Strains: 1, R1DC9T (data from this study); 2, Marivirga tractuosa DSM 4126T [17]; 3, Roseivirga ehrenbergii SW-152T [64]; 4, Roseivirga misakiensis SK-8T [62]; 5, Fulvivirga kasyanovii KMM 6220T [63]. nd, Not detected. Bold indicates the prevalent fatty acid components in strain R1DC9T (i.e., > 5 %). Fatty acids accounting for less than 1 % in all the strains are not reported; tr, trace (<1 %).

*Summed features are groups of two or three fatty acids that could not be separated via GLC using the midi system. Summed feature 3 comprises iso-C15 : 0 2-OH and/or C16 : 1 ω7c and/or C16 : 1 ω6c and/or and/or iso-C15 : 0 2-OH. Summed feature 4 comprises iso-C17 : 1 and/or anteiso-C17 : 1 B.
