Table 1. Diacetyl production of the isolated LAB

Strain Diacetyl (mg/L)
L. casei ATCC393 10.97±0.55a
L. lactis cremoris LL5306 13.20±0.54b
L. casei LC5229 10.70±0.35a
L. lactis cremoris LL5301 8.13±0.66b
L. casei LC5316 7.90±0.75b
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.
