a Cholesterol lowering effect of the cell-free supernatant (CFS) at various concentrations (a). Effect of pH (b) and temperature (c) on cholesterol-lowering ability of CFS. Values are given as the mean ± SD of three separate experiments. Different lowercase letters indicate significant differences in cholesterol reduction for that culture at that concentration and time point (a) and significant differences between cultures at the variable tested (X-axis) (b, c)
