Table 4. Major fatty acid contents of strains representing the four novel species of the genus Polynucleobacter.
Data for strains QLW-P1DMWA-1T, MWH-JaK3T and MWH-HuW1T were taken from Hahn et al. (2009); however, fatty acid methyl esters had been prepared and measured under the same conditions as for strain MWH-MoK4T.
