Formulation and Antibacterial Activity Test of Salmonella thypimurium and Lactobacillus acidophilus in Microencapsulation of Mangosteen Peel Extract

Xanthone compounds in the ethanol extract of mangosteen peel have antibacterial activity against both pathogenic and beneficial bacteria. The purpose this study was to examine effect various formulations maltodextrin from palm starch on Salmonella thypimurium Lactobacillus acidophilus. This research conducted by culturing bacterial cultures S. L. acidophilus nutrient agar (NA) media petri dishes according Kirby-Bauer method. NA that had been made dish then wells test each treatment as much 10 µL/disk at concentrations (100, 75 50%). tested consisted of: T1 (30% + 70% maltodextrin), T2 (40% 60% T3 (50% 50% % T4 (60% 40% T5 (70% 30% T6 (ethanol only), T7 (maltodextrin T8 (positive control containing 100 ppm bacitracin) T9 (negative control/no treatment). results sample were observed measuring inhibition zone growth medium prepared. Data analyzed using one-way ANOVA followed Duncan's test. showed a significant (P<0.05) indicated formulation ability an level.
