The BLS from all 28 LAB isolates lost their anti-listerial activity following treatment with proteinase K, a-chymotripsin and/or trypsin (Table 2). However, when Lact. sakei was used as an indicator, the BLS produced by the different LAB stains had varying activity following treatment with these enzymes. Nevertheless, the lost antimicrobial ability following treatment with proteolytic enzymes indicated the proteinaceous nature of the BLS.
05). 2. A combined treatment of decanol (20-ppm) and nisin (50 IU) showed significant inhibition on the total L. monocytogenes population (P < 0. 05), resulting in an enhanced anti-listerial activity of nisin in the presence of decanol. 3. Decanol appears to be an effective option for controlling L. monocytogenes in Ready-To-Eat meat and meat products. ImpactsThe focus of our research is pre- and post-harvest food safety and quality control.
