Pediococcus acidilactici / Postbiotics Powder

Pediococcus acidilactici, a species produced by Lactococcus lactis, exhibits the remarkable ability to inhibit a diverse range of Gram-positive bacteria, alongside a limited number of Gram-negative bacteria, thus indicating an extensive antimicrobial spectrum. This characteristic holds substantial practical implications for the advancement of effective, broad-spectrum biopreservatives, which are crucial in food preservation and safety. Generally, bacteriocins derived from lactic acid bacteria do not demonstrate inhibitory effects against Gram-negative bacteria unless a preliminary treatment is applied to those bacteria. Notably, the bacteriocins synthesized by Lactococcus reveal a wide array of antibacterial activity, encompassing the suppression of non-lactobacilli Gram-positive bacteria typically associated with food spoilage and various pathogenic microorganisms. Furthermore, they also display inhibitory action against lactic acid bacteria like non-pathogenic Lactobacillus, Lactococcus, Enterococcus, and Lactobacillus plantarum. In addition, these bacteriocins are effective against food spoilage or pathogenic bacteria, including Bacillus cereus, Staphylococcus aureus, and Listeria monocytogenes. The antimicrobial compounds extracted from Lactococcus lactis in this investigation have demonstrated effective inhibition of Gram-positive bacteria such as Listeria monocytogenes, Lactobacillus plantarum, Staphylococcus aureus, and Bacillus cereus. This illustrates a broad inhibition spectrum along with significant potential for practical applications within the realm of food safety and biopreservation.
