Abstract: In addition to being used as food bioconservants, some bacteriocinogenic cultures have been employed to accelerate cheese ripening. However, the compatibility between their growth and starter cultures is essential to obtain the characteristic products. The purpose of this study was to evaluate the growth compatibility between Lactococcus lactis subsp. lactis ATCC 11454, Lactobacillus plantarum ALC 01, and Enterococcus faecium FAIR-E 198 and two commercial starter cultures. Initially, the sensibility in vitro of the starter to bacteriocinogenic cultures by an agar well diffusion assay was determined. Only Lc. lactis subsp. lactis ATCC 11454 was able to cause the inhibition of both starters. During the associative growth in milk at 35°C, the bacteriocinogenic cultures did not affect the lactic acid production due to the starter cultures. Futhermore, the starter cultures provided a significant increase in the activity of pediocina AcH and enterocin FAIR-E 198. They also suppressed the nisin activity. Among all lactic cultures, Lb. plantarum ALC 01 showed the highest aminopeptidase activity (0,226 to 0,390). Therefore, according to these results Lb. plantarum ALC 01 and E. faecium FAIR-E 198 showed growth compatibility characteristics with the starter cultures and thus can be used as adjunct cultures in cheese making.
