Table 2.
Major fatty acid compositions of the Polynucleobacter strains representing subcluster PnecC. Strains were grown on R2A agar. Data for strains QLW-P1DMWA-1T, MWH-HuW1T, MWH-JaK3T were taken from (Hahnet al., 2009) and data for MWH-Mok4T from Hahn et al. (2016b).

Summed features represent groups of two fatty acids which could not be separated by GLC and the MIDI system, such as summed feature 2 containing C16:1 isoI and C14:0-3OH and summed feature 7 containing C19:1 ω6c and an unknown compound with an ECL of 18.846, or represent compounds with uncertain identity such as summed feature 1 probably containing C12:0 ALDE?.
