^aAll 50 strains from this study plus the reference strain DSM 20682. ^bFor all other fatty acids, EC strains were negative or mean value was >0.27 and feature not used by MIDI system. ^cSummed features represent groups of two fatty acids which could not be separated by gas chromatography with the MIDI system. Summed feature 3 contains C_15:0 iso 2OH and C_16:1 w7c. Summed feature 5 contains C_18:0 anteiso and C_18:2 w6,9c
