Uji Daya Hambat Filtrat Zat Metabolit Lactobacillus plantarum Terhadap Pertumbuhan Shigella dysenteriae Secara In Vitro

Abstract: Shigella dysenteriae is pathogenic bacteria causes dysentery diarrhea, a diarrhea with mucus and blood in the feces. Currently, drugs or foods containing Lactobacillus have been circulated in the markets and used by people. This research aims to know the in vitro inhibition test of L. plantarum metabolite substances filtrate against growth of S. dysenteriae. This research used experimental design with L. plantarum metabolite substances filtrate as the samples. Antibacterial test method which was used was the c… Show more

“…Staphylococcus aureus and Escherichia coli are bacteria that often found in the udders of dairy cattle, and these two bacteria have the potential to infect udder tissue causing mastitis in dairy cattle (Artdita et al, 2020;Fesseha et al, 2021). The increasing concentration of eco-enzyme solution resulting high concentration of antibacterial compounds that diffuse in the agar medium and produced enlarged inhibition zone; otherwise, the decrease in the diameter of the inhibition zone is caused by the reduced effectiveness of antibacterial compounds from the level of eco-enzyme solution used (Welfalini et al, 2023;Rahma et al, 2017). The clear zone formed at a concentration of 100% is almost the same (p>0.05) as the results on synthetic antiseptic solution.…”

“…Mirdalisa et al (2016) menyatakan aktivitas mikroba dipengaruhi oleh suhu pertumbuhan dalam menghambat bakteri patogen sehingga senyawa organik yang berperan sebagai senyawa antibakteri juga ikut terpengaruh. Menurut Rahmah et al (2017), daya hambat pada probiotik fermentasi maggot disebabkan karena jumlah mikroba penghasil antibiotik khususnya bakteri pada probiotik yang menghasilkan asam organik (asam laktat dan asam asetat). Penelitian yang dilakukan oleh (Widianingsih & Yunita 2018) terkait efektivitas probiotik single dan multi strain terhadap E. Coli menyatakan bahwa banyaknya jumlah bakteri yang terkandung pada cairan probiotik berkorelasi positif dengan kadar asam organik yang berperan sebagai senyawa antimikroba dan membentuk zona hambat.…”

“…Hal ini karena semakin tinggi konsentrasi bahan antimikroba, maka semakin banyak pula zat aktif yang terkandung di dalamnya sehingga efektivitas dalam menghambat bakteri akan semakin tinggi dan menghasilkan zona hambat yang lebih luas. Sebaliknya, pada konsentrasi yang rendah, zat antimikroba yang terdapat di dalam suatu bahan antimikroba akan semakin sedikit, sehingga aktivitas dalam menghambat bakteri akan semakin berkurang (Rahma et al, 2017)…”
