Linear models demonstrated a highly significant effect of the strain factor (χ 2 = 483.04, p = 0.001425) on the MTBE tolerance and on the PFOA tolerance (χ 2 = 590.87, p = 4.613 × 10 −10 ) by suggesting a high variability among the strains in response to both POPs tested ( Supplementary Data Set S6 ).
