ABSTRACT
Background: Pekasam is a fermented product made from fish through a salting process with the addition of rice and incubated in a closed container for 4-10 days. The dominant bacteria that grow in pekasam are lactic acid bacteria. LAB have the potential to produce antimicrobial compounds that can inhibit the growth of pathogenic bacteria.
Objectives: The aim of this study is to isolate LAB from pekasam and determine its antimicrobial activity against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Salmonella typhi, and Pseudomonas aeruginosa.
Methods: This study used a descriptive method with parameters such as total LAB colonies, microscopic and macroscopic morphology, and LAB antimicrobial activity
Results: Total LAB colonies in this study ranged from 8,13×105–2,20×107 CFU/mL. The result of morphological identification showed that 32 isolates were bacilli and 1 were cocci with round-shape, flat edges, convex elevation, white and white-yellowish colors, and Gram positive. Based on antimicrobial activity, the highest (2,78 mm) inhibition zone was found in sample SB1 against Bacillus subtilis and the lowest (1,62 mm) was found in sample SB2 against Pseudomonas aeruginosa.
Conclusion: The antimicrobial activity of all LAB isolates was categorized as weak because the inhibition zone was <5 mm.
