The G+C content of the genomic DNA of strain ck-I2-15T
was determined by reverse-phase HPLC using the method
described by Mesbah & Whitman (1989). The DNA G+C
content of strain ck-I2-15T was 38 mol%, which was similar
to the value recorded for G. mesophilus Mok-17T (37 mol%;
Khan et al., 2007). Analysis of the respiratory quinones and
polar lipids were carried out by the Identification Service of
the Deutsche Sammlung von Mikroorganismen und
Zellkulturen (DSMZ), Braunschweig, Germany. The major
quinone of strain ck-I2-15T was identified as MK-6 (96 %),
the major quinone of all current members of the genus
Galbibacter. The polar lipid profile of strain ck-I2-15T
comprised phosphatidylethanolamine, one unidentified
phospholipid, two unidentified aminolipids, one unidentified
glycolipid and four other unidentified lipids (Fig. S2).
