Molar mass recoveries for catabolites were expressed as percentage with respect to the incubated concentration of parent compound (75 μmol L 1 –). Data are expressed as mean ± SD (n = 3). n.d.: not detected; Cell colors range from light to dark blue, indicating the range from low to high molar mass recovery for each catabolite over time: dark color is reported only when light color was indicated. *p < 0.05; **p < 0.01; ***p < 0.001, indicate significant differences comparing the same fermented substrate after different incubation period.
