| Acid | Subjectsa
|
|||
|---|---|---|---|---|
| Aneg group

Apos group
|
|||
| Concn (mM) | % | Concn (mM) | % | |
| Acetate | 42.4 (7.8)b | 56.8 | 46.1 (9.1) | 56.9 |
| Propionate | 14.9 (5.9) | 20.0c | 10.8 (5.2) | 13.3c |
| Butyrate | 17.4 (5.9)d | 23.2e | 24.1 (10.3)d | 29.8e |
a
The values are the averages of the values from two or three fermentations for each sample. The percentages are percentages of the total concentration of the three SCFA.
b
The values in parentheses are standard deviations.
c
The difference between the Aneg group value and the Apos group value is significant (P < 0.002), as determined by Student’s t test.
d
The difference between the Aneg group value and the Apos group value is significant (P < 0.02), as determined by Student’s t test.
e
The difference between the Aneg group value and the Apos group value is significant (P < 0.02), as determined by Student’s t test.
