Figure 2. SCFA and BCFA concentration in i-screen. SCFA and BCFA were measured in absolute amounts (mmol/L) in the pre-culture at t = 0 h, or after 24 h of fermentation in the i-screen. The black bars represent statistical comparisons between the different conditions. They indicate where a significant (P < 0.05) difference in short-chain fatty acid concentrations was detected. SCFA: Short-chain fatty acid; BCFA: branch-chain fatty acid.
