Average cumulative short chain fatty acid (SCFA) production in mmol (A) and SCFA increase in mmol/g substrate/24 h (B) for non-processed RSM (CON) and RSM processed by Accellerase 1000 (CELL), Pectinex Ultra SP (PECT1), Multifect Pectinase (PECT2), or 6 M NaOH (ALK). The values at time point 0 were artificially set to 0 to allow determination of cumulative production. (C) correlation between SCFA production and core genera, *p < 0.05; blue: positive correlation; red: negative correlation. Core genera: the table was normalized via division by the sum of sequences in a given sample and multiplied by the minimum sum across all samples. Relative abundances were filtered as follows: values below a relative abundance threshold of 0.01% were not taken into account; taxa with a median relative abundance < 1% in all groups were not considered for statistical analysis.
