a
The inoculum was grown in BHI medium or IMM containing 6% (wt/vol) soy protein hydrolysate (SP) with or without 5 mM 2-methyl butyrate (2-MB).
b
Omega allicyclic minor fatty acid components are not included in this table.
c
Values are representative of the results of two independent experiments.
d
Short-chain fatty acid (SCFA) values represent cumulative percentages of straight-chain fatty acids with either an odd- or an even-numbered-carbon-chain length.
e
Iso-BCFA values represent cumulative percentages of iso-BCFAs with either an odd- or an even-numbered-carbon-chain length.
f
Anteiso-BCFA values represent cumulative percentages of anteiso-BCFAs with an odd-numbered-carbon-chain length.
