Bacteriocin-producing Pediococcus acidilactici BAMA 15 isolated from "naniura" traditional foods in North Sumatra, Indonesia

Abstract. Nasution SA, Fachrial E, Ginting CN, Liena, Piska F. 2023. Bacteriocin-producing Pediococcus acidilactici BAMA 15 isolated from "naniura" traditional foods in North Sumatra, Indonesia. Biodiversitas 24: 2830-2835. Lactic Acid Bacteria (LAB) have beneficial properties for their hosts, potentially promoting health and balancing the normal gut flora. Meanwhile, bacteriocin is a bacteriostatic polypeptide used as food preservative. LAB are generally produced fermented products, such dengke naniura, typical Toba Batak food. Therefore, it estimated that present this has potential probiotic produces bacteriocin, an antimicrobial compound. The purpose of study was to identify species found naniura characterize generated by them. first stages included isolation biochemical morphological characterization LAB. Nine isolates (BAMA 10-11, 15-20, 25) were samples. best strain use because its activity against E. coli S. aureus 6.44 7.53 mm, respectively. molecular weight be ?12 kDa.
