Three fermentations in skim milk were used to study the effectiveness of the bacteriocin-producing Streptococcus macedonicus ACA-DC 198 strain to inhibit Clostridium tyrobutyricum LMG 1285T spore outgrowth under conditions prevailing during Kasseri cheese production and ripening. in fermentation A, Clostridium spores were used solely; in fermentation 13, S. macedonicus ACA-DC 198 and Clostridium spores were used; in fermentation C, a commercial starter culture and Clostridium spores were used. The temperature program applied was similar to that of Kasseri cheese production and ripening. The presence of macedocin, the bacteriocin produced by S. macedonicus ACA-DC 198, was confirmed in fermentation B. The results showed that macedocin was able to inhibit the outgrowth of Clostridium spores, since significantly higher inhibition in spore outgrowth was detected in fermentation B than in fermentation C.
