Values with different letters (A, B, and C) in a row indicate that they are significantly different from each other (P < 0.05).
b
N[Clostridia], N[C. kluyveri], and N[LAB] represent the absolute abundances (log10 16S rRNA gene copies/gram of FPM) of Clostridia, C. kluyveri, and LAB in FPM samples, respectively.
