Abstract
The effect of a bacteriocin-producing strain, Lactobacillus sakei Lb706, on the behavior of Listeria monocytogenes in
rainbow trout fillets stored under vacuum at 4 ºC for 14 days and at 10 ºC for 5 days was investigated.
At 4 ºC, growth of L. monocytogenes was significantly inhibited (P < 0.05) by L. sakei Lb706 during 10 days of storage while
bacteriocin–negative Lb706-B did not affect the growth of L. monocytogenes during 14 days of storage. In the presence of the
sakacin A-producing strain of L. sakei (Lb706), the growth of L. monocytogenes was significantly inhibited (P < 0.05) in the first 3
days of storage at 10 ºC, after which its count increased to 107 CFU/g. The control group and the group containing L. sakei Lb706-
B showed similar growth patterns of L. monocytogenes. Significant increases (P < 0.05) were observed in all groups in terms of
psychrotrophic bacteria counts. No significant (P > 0.05) changes in pH values during storage at 4 ºC and 10 ºC were determined.
Consequently, the results of the present study showed that L. sakei Lb706 can be used as a protective culture in freshwater reared
rainbow trout, especially for pre
