Effect of glutamate (CDMg) and yeast extract (CDMgYE) on cell growth, final pH, and GABA production in a chemically defined medium (CDM) by L. brevis CRL 2013 after 48 h of Incubation.
| Culture media | Specific growth rate (h−1)a | GABA production (mM)a | Log CFU/mLa | Final pHa,b |
|---|---|---|---|---|
| CDM | 0.20 ± 0.01 | ND | 8.83 ± 0.09 | 4.92 ± 0.12 |
| CDMg | 0.21 ± 0.01 | ND | 8.80 ± 0.10 | 5.00 ± 0.16 |
| CDMgYE | 0.36 ± 0.02 | 260.34 ± 5.11 | 9.41 ± 0.09 | 7.70 ± 0.13 |
a
Results are presented as means ± standard deviations from at least 3 independent biological replicates. ND, not detected.
b
The initial pH of all CDM was approximately 6.5.
