FIGURE 2

Membrane fatty acids (% of total membrane fatty acids) of Propionibacterium freudenreichii CIRM-BIA 129 in different conditions. The fatty acids composition (A), the saturated/unsaturated fatty acids ratios (SFA/UFA) (B), the saturated/branched fatty acids ratio (SFA/BFA) (C) and the C15-C22/C10-C14 ratio (D) are shown for the strain grown in YEL and YEL+NaCl broths and subjected to heat and acid adaptation. Error bars represent the standard deviation for triplicate experiments. Significant differences are reported with different letters above the columns (p > 0.05). YEL: Yeast Extract Lactate. 42°C, 1 h: thermo-adaptation at 42°C during 1 h. pH = 5, 1 h: acid-adaptation at pH = 5 during 1 h.
