- The purpose of the study was to compare the antibacterial activity of Lactobacillus casei subsp. casei R-68 and Lactobacillus casei commercial against Staphylococcus aureus FNCC-15 and Escherichia coli FNCC-19. The research was carried out experimentally by testing isolates of Lactobacillus casei subsp. casei R-68 and Lactobacillus casei commercial in a petri dish that already contains pathogenic bacteria. Antibacterial activity was tested using the well diffusion method, the data obtained were analyzed descriptively. The results showed that Lactobacillus casei subsp. casei R-68 has the ability to inhibit pathogenic bacteria by inhibition smaller than Lactobacillus casei commercial. The average inhibition zone diameter of lactic acid bacteria isolates against Staphylococcus aureus FNCC-15 ranged from 7.40 to 8.10 mm and Escherichia coli ranged from 9.80 to 10.23 mm. Keywords : Antimicrobials, Lactic acid, Lactobacillus casei subsp. casei R-68, Lactobacillus casei commercial.
