Table 3.
Whole cell fatty acid composition of P. cosmopolitanus sp. nov. strains as compared to the type strain of P. necessarius subsp. asymbioticus, QLW-P1DMWA-1T, (Hahn et al., in press). Values are percentages of the summed fatty acids named in the peak library of the MIDI system (contents > 0.2%). Strains were grown on R2A agar plates for 3-5 days at 28° C.
