PERBANDINGAN AKTIVITAS ANTIBAKTERI ANTARA Lactobacillus casei subsp. casei R-68 DAN Lactobacillus casei KOMERSIL TERHADAP Staphylococcus aureus FNCC-15 DAN Escherichia coli FNCC-19
Abstract: 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.
