Figure 9.
Gallic acid and chlorogenic acid (0–10 mM) relative choline percentage increase effect against choline-supplemented (100 µM) conditions (A,B). Gallic acid and chlorogenic acid (0.1–10 mM) relative TMA percentage decrease effect against choline-supplemented (100 µM) conditions (C,D). All fermentations were carried out at optimal conditions (fecal slurry 20% and choline 100 µM). Results are expressed as mean (%) ± SEM (n = 6). Different letters indicate statistical differences (p < 0.05) by one-way ANOVA (Tukey’s post hoc test). Abbreviations: TMA, trimethylamine; GA, gallic acid; and Chl, chlorogenic acid.
