The bacteriocin producer strain P. acidilactici 13 was able to grow in a
wide temperature range, between 25 and 50 °C and to sustain growth at
10% NaCl concentration. These characteristics have considerable interest
in food systems especially fermentation processes. It was seen that,
bacteriocin production was affected by the culture conditions such as
temperature and pH of the medium. With initial pH of the medium at 6.0
and incubation temperature 37 °C, bacteriocin activity of the strain
reaches the highest value of 204,800 AU/mL. The strain identified as
P. acidilactici by API 50 CHL and 16S rRNA gene sequencing is a promising
isolate for the food systems with a view to use as protective culture.
Further experiments like utilization of the strain in fermentation
processes or using the antimicrobial substance in the form of a
preparation can exhibit great outcomes
