Fatty acid profiles of strain 2012CJ34-3<sup>T</sup> and related species of the genus <italic>Jejuia</italic> and <italic>Gaetbulibacter</italic>

Strains: 1, Jejuia spongiicola 2012CJ34-3T; 2, Jejuia marina KCTC 42342T; 3, Gaetbulibacter lutimaris KCTC 23716T; 4, Gaetbulibacter aquiaggeris KCTC 42198T; 5, Gaetbulibacter marinus KCTC 23081T.

All strains were cultured on MA medium for 48 h at 25°C. Some fatty acids amounting to < 0.5% of the total fatty acids in all strains are not listed. tr, trace amounting (< 0.5%); –, not detected.

*Summed features are fatty acids that cannot be resolved reliably from another fatty acid using the chromatographic conditions chosen. The MIDI system groups these fatty acids together as one feature with a single percentage of the total.
