Fourteen bacteriocin-producing strains from the genera Lactobacillus, Leuconostoc, Pediococcus, and Lactococcus were evaluated for their ability to inhibit the growth of eight strains of Listeria monocytogenes. Seven strains of lactic acid bacteria were antagonistic toward L. monocytogenes by deferred antagonism testing on agar. Cell-free supernatants from cultures of three of the seven bacteriocin-producing strains which inhibited growth of L. monocytogenes in deferred antagonism testing also inhibited growth in well diffusion assays. The eight strains of L. monocytogenes were identical in their sensitivity or resistance to bacteriocins. The action of the bacteriocins was eliminated by proteolytic enzymes.

The aim of the research was to find the potency of Lactic Acid Bacteria isolated from breast milk on inhibiting Listeria monocytogenes FNCC 0156 and to find the magnitude of lactic acid bacteria from breast milk in inhibiting L. monocytogenes FNCC 0156. This reseach consists of two phase: antimicrobial activity of lactic acid bacteria from breast milk and activity of bacteriocin against L. monocytogenes FNCC 0156. Isolate used in this research was A1, A3, A6, A8, A9, B3, B7, B8, and B10b. Antimicrobial activity of lactic acid bacteria from breast milk against L. monocytogenes FNCC 0156 was performed cell free supernatant, cell free neutral supernatant, and cell free neutral heated supernatant. The test was performed by well-agar diffusion method and contact method. The activity of bacteriocin was carried out according to the optimum incubation time of bacteriocin production in cell free heated neutral supernatant. The highest antimicrobial activity was supernatant treatment by well-agar diffusion method and contact method showed by isolate A1 with inhibition diameter of 10.60 mm and a decrease of 1.66 log cycle. The highest antimicrobial activity was neutral supernatant treatment by well-agar diffusion method and contact method showed by isolate B8 with inhibition diameter of 5.11 mm and increased only by 0.18 log cycle. The highest antimicrobial activity on the heated neutral supernatant treatment by well-agar diffusion method and contact method showed by isolate A6 with inhibition diameter of 0.85 mm and a decrease of 0.48 log cycle. The two isolates of cell free neutral heated supernatant treatment was isolate A6 and isolate B8 suspected to have bacteriocin compounds was then continued with isolation of bacteriocin. The result of the second phase showed that optimum time for bacteriocin production of isolate A6 was 36 hours and B8 was 60 hours. The highest antimicrobial activity of bacteriocin was showen by isolate A6 with an average inhibition diameter of 5.36 mm, followed by B8 with an average inhibition diameter of 2.44 mm.

Abstract. Melia S, Purwati E, Kurnia Y. F, Pratama D. R. 2019. Antimicrobial potential of Pediococcus acidilactici from Bekasam, fermentation of sepat rawa fish (Tricopodus trichopterus) from Banyuasin, South Sumatra, Indonesia. Biodiversitas 20: 3532-3538. This study aimed to determine the antimicrobial potential of lactic acid bacteria isolated from bekasam. Bekasam is a result of sepat rawa fermentation from Banyuasin District, South Sumatra, Indonesia. The results showed that the morphological and biochemical properties of lactic acid bacteria were Gram-positive and cocci, negative catalase and included in homofermentative groups. The biggest antimicrobial activity was shown by bekasam isolate to Escherichia coli O157: H7 (21.26 mm), followed by Staphylococcus aureus ATCC25923 (18.23 mm) and Listeria monocytogenes CFSAN004330 (5.10 mm), while diameter barriers for crude bacteriocin supernatant isolates lactic acid bacteria to Escherichia coli O157: H7, Staphylococcus aureus ATCC25923 were 14.99 mm, 17.69 mm, and Listeria monocytogenes CFSAN004330 had no antimicrobial activity at neutral pH. The results of molecular identification with 16S rRNA showed that lactic acid bacteria isolated from bekasam isolate have similarity with Pediococcus acidilactici strain PB22 that has antimicrobial potential against pathogenic bacteria and potential as bio preservatives.
