Table 3. Comparison of diacetyl production at different culture temperatures
Temperature (°C) | Diacetyl (mg/L) |
LRCC5306 | ATCC393 |
0 | 0.0 | 0.0 |
10 | 0.0 | 0.0 |
20 | 20.64±0.51d | 15.41±0.21c |
25 | 18.32±0.64c | 10.52±0.16a |
30 | 14.25±0.13b | 10.96±0.15a |
37 | 11.48±0.16a | 11.61±0.29b |
Results are expressed as mean±SE (n=3).
L. casei ATCC393 was used as the reference strain. The initial concentration of diacetyl was 0.
Means in the same column with different lowercase superscript letters are significantly different at p<0.05.
