1Tot SCFA=total short-chain fatty acids (acetic+propionic+butyric+iso-butyric+valeric+iso-valeric+caproic+isocaproic acid; mg l-1); Ac=acetic acid; Pr=propionic acid;
Bu=butyric acid; BC=branched-chain SCFA; Ac (%), Pr (%), Bu (%), BC (%)=acetic, propionic, butyric and branched-chain acid as relative proportion to Tot SCFA.
Mean values with different superscripts within the same column and incubation time point differ significantly (p<0.05). |
