Table 1.
The mean pH and OD600 of the samples after 14 days of LB672 fermentation in different medium compositions. Values are the mean ± standard error of two replicates. Values with different superscript lowercase letters (a–b) in the row (either pH or OD600) are significantly different according to Tukey’s test at p< 0.05.

| pH | OD600 | pH | OD600 | ||
| DM | 5.67 ± 0.035 a | 4.47 ± 0.011 b | 1.40 ± 0.005 a | 4.44 ± 0.1 b | 1.20 ± 0.005 b | 
| DMFr | 5.68 ± 0.025 a | 4.72 ± 0.03 b | 1.26 ± 0.06 a | 4.65 ± 0.04 b | 1.06 ± 0.04 b | 
| DMCi | 6.27 ± 0.005 a | 6.27 ± 0.0045 a | 0.07 ± 0.005 a | 6.27 ± 0.0005 a | 0.05 ± 0.0025 a | 
DM: original defined medium (glucose); DMFr: defined medium with fructose; DMCi: defined medium with citrate.
