| Strain | Specific growth rate (h−1)a on:
|
|
|---|---|---|
| Starch | Fructo- oligosaccharides | |
| B. adolescentis L2-32 | 0.40 ± 0.007 | 0.20 ± 0.012 |
| B. adolescentis DSM 20083 | —b | 0.56 ± 0.045 |
| B. adolescentis DSM 20086 | — | 0.42 ± 0.011 |
| B. angulatum DSM 20098 | 0.41 ± 0.024 | 0.45 ± 0.085 |
| B. bifidum 70/18 | 0.26 ± 0.090 | — |
| B. breve DSM 20213 | — | 0.21 ± 0.006 |
| B. longum (biotype longum) DSM 20219 | — | 0.30 ± 0.062 |
| B. longum (biotype longum) NCIMB 8809 | — | 0.15 ± 0.026 |
| B. longum (biotype infantis) 20088 | — | 0.54 ± 0.041 |
| B. pseudocatenulatum DSM 20438 | 0.16 ± 0.053 | 0.45 ± 0.042 |
a
Values are means of three replicates ± standard deviations.
b
—, poor growth (final ΔOD of <0.13). B. bifidum DSM 20456 and B. breve NCIMB 8807 were also tested but gave final ΔODs of <0.1 on both substrates.
