Table 4. Fatty acid composition of three Paraburkholderia sp. nov.
The Paraburkholderia sp. nov. type strains contain large proportions of cyclopropane fatty acids (CPA) compared to non-symbiont control Paraburkholderia. The three symbiont Paraburkholderia type strains show similar fatty acid profiles. Minor fatty acids (abundances < 0.2%) are not reported.

Notes.
*
SM/5 growth media contained C16:1. Media could have contributed up to one third of C16:1 at high estimates of media contamination of biomass collected for symbiont Paraburkholderia sp. nov.
