Bacteriocin production and sensitivity.
Using an overlay test the production of bacteriocin-like activity and resistance was found in 6 of the total of 7 isolates (5 enterococcal and 2 streptococcal). The majority of strains were sensitive to all bacteriocin producers tested. After acetone precipitation, bacteriocin precipitates were tested for thermal stability. They exhibited high stability at 37 degrees C and some of them were active even after a treatment at 95 degrees C.
