Abstract
The production of leuconocin S, a bacteriocin from Leuconostoc parames enteroides OX, was examined during batch fermentations at pH 6.0, 6.5, 7.0 and 7.5. The specific growth rate and bacteriocin titers were hig hest at pH 7.0, with values of 0.33 h(-1) and 20 000 AU/ml, respective ly. Maximum bacteriocin production corresponded to late logarithmic-ea rly stationary growth phase. Bacteriocin levels decreased during late stationary phase, possibly due to proteolytic enzymes produced during this period.
