Abstract

The objectives of this study was to observe antibacterial activities of water lily seed, against diarrhea-causing pathogenic bacteria as well as lactic acid bacteria; phytochemistry components in water lily seed and to evaluate each component?s activities against pathogen bacteria. Extraction of antibacterial components in the seed was done by fractional extraction methods using solvent based on its polar level, i.e. hexane, ethyl acetate and ethanol. The activities of each extract was tested by using diarrhea-causing bacteria, Enteropathogenic Escherichia coli K.1.1 (EPEC K1.1) and S. typhimurium with agar well diffusion method. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values were calculated with plate counting. Qualitative phytochemical tests were performed on all extracts. Fractionation was performed on extract with the largest antimicrobial activity by using thin-layer chromatography. The activities of each fraction were tested qualitatively by bio-autography method on thin layer chromatographic plates. The water lily seed had an antibacterial activity against EPEC K.1.1 and Salmonella typhimurium, especially in ethyl acetate extract. Ethanol extract had the same, yet lower activity. Ethyl acetate and ethanol extract of the seed did not show inhibition against the growth of lactic acid bacteria (Lactobacillus sp) and Bifidobacterium bifidum. The MIC and MBC values of the ethyl acetate extract on EPEC K1.1 were 0.89 (mg/mL) and 1.33 (mg/mL), respectively, while similar values of that on S. Typhimurium were 1.11 (mg/mL) and 1.33 (mg/mL¬), respectively. Phytochemistry components within ethyl acetate extract were alkaloids, flavonoids, tannins, glycosides, saponins, and triterpenoids. All fractions in the ethyl acetate extract had antimicrobial activities against EPEC K.1.1 and S. Typhimurium. These fractions were thought to inhibit the growth of the test-microbes by synergic action of each component.Key words: water lily seed, antibacterial, ethyl acetate extract

Abstract

In vitro analysis of oligosaccharide from extract rumbia fruit (Metroxylon sago Rottb.) as prebioticABSTRACT. Despite a range of commercially available oligosaccharides there is plenty of room to develop new, functionally enhanced prebiotics. current generation of oligosaccharides was not rationally developed. better understanding of factors determining the prebiotic activity of a particular oligosaccharide. Despite the range of commercially available oligosaccharides mixtures (mainly fructo and galacto-oligosaccharides), very few studies are focused on the mechanisms behind the prebiotic activity of particular oligosaccharides. Probably this lack is due to the unavailability of well characterized oligosaccharide fractions for prebiotic function assessment. The objectives of this research were to asses the ability of lactic acid bacteria in fermentation of oligosaccharide and as prebiotic (in vitro). Material used was oligosaccharide of purified rumbia fruit extract. Analysis of oligosaccharide as prebiotic was conducted in vitro using lactic acid bacteria. The lactic acid bacteria consisted Bifidobacterium bifidum, Bifidobacterium animalis, Lactobacillus bulgaricus and Lactobacillus casei Rhamnosus. The growth media for bacteria was a liquid MRS basic medium where glucose was substituted by oligosaccharide of purified rumbia fruit extract. Incubation was in aerob for Lactobacillus and anaerob for Bifidobacterium in incubator 37oC. The lactic acid bacteria was calculated 24-48 hours during incubation periode. The variables observed were: oligosaccharide component, ability of lactic acid bacteria in fermentation of oligosaccharide, and growth of lactic acid bacteria (Lactobacillus and Bifidobacterium). The result showed that the oligosaccharide component from extract rumbia fruit consisted of: sucrose, stacchiose, and raffinose. The result showed that the oligosaccharide extract rumbia fruit was significantly (P<0.05) the growth of lactic acid bacteria (Lactobacillus and Bifidobacterium) and fermentation of oligosaccharide. It is concluded that oligosaccharide of rumbia fruit extract could be used as prebiotic.

Abstract

Lactic acid bacteria (LAB) regarded as safe microorganisms; they can naturally live in gastrointestinal tract, so appropriately used as a probiotic for chicken. This study aimed to select six isolates of LAB (E1223, E3, E4, E5, E7, and E8) to obtain the isolates potentially as probiotic candidate for chicken. The six isolates were derived from spontaneous fermented corn obtained from Laboratory of Animal Biotechnology and Biomedical, PPSHB, Bogor Agricultural University, Indonesia. LAB isolates were tested their susceptibility to antibiotics (bambermycin, erythromycin, chloramphenicol, and tetracycline) then were examined in vitro for their tolerance to gastrointestinal pH (2, 3, 4, and 7.2) and 0.5% bile salt condition, antimicrobial activity against Salmonella enteritidis and Enterococcus casseliflavus, and ability to adhere to chicken ileal cells. The results showed the isolates E5, E7, and E8 were sensitive to tetracycline and chloramphenicol, they could survive at pH 2, 3, 4, and 7.2, could survive at 0.5% bile salts, produced antimicrobial activity, and able to adhere to ileal cells (9.40±0.00 Log CFU/cm2 of E8) and were significantly (P&lt;0.05) higher than those of control (5.30±0.14 Log CFU/cm2). In conclusion, this study showed that isolate E8 had better potential compared to isolates E5 and E7 in most in vitro assays as a probiotic candidate for chicken. E5, E7, and E8 were closely related with Pediococcus pentosaceus based on 16S rRNA gene.Key words: LAB, probiotic, chicken, in vitro

Abstract

Effect of prebiotic oligosaccharide extract rumbia fruit (Metroxylon sago Rottb.) in the ration on broiler performanceABSTRACT. Prebiotic oligosaccharides are thought to provide beneficial effects in the gastrointestinal tract of humans and animals by stimulating growth of selected members of the intestinal microflora. Prebiotic oligosaccharides are defined as nondigestible food ingredients that provide beneficial effects to the host by stimulating the growth of selected microbial members of the gastrointestinal tract. Among the colonic bacteria capable of metabolizing prebiotic oligosaccharides and whose growth is stimulated are species of Lactobacillus and Bifidobacterium. Prebiotic oligosaccharides can be produced in transgli-cosylation reactions catalyzed by glycosidases. Glycosidases from different biological sources have specific ability to catalyze the formation of oligosaccharides with particular chain lengths (usually DP < 7) and predominant glycosidic linkages. Oligosaccharide used this research was purified rumbia fruit extract as prebiotic for feed additive in the ration on broiler. The objectives of this research were to study the performance of broiler given of prebiotic oligosaccharide extract rumbia fruit (metroxylon sago Rottb.) in the ration. Two hundred day-old chicks of broiler were divided into three dietary treatments and four replications. Ration used was consisted of: R1 = basal ration (control), R2 = basal ration + 0,4% oligosaccharide extract rumbia fruit, and R3 = basal ration + 0,4% frukto-oligosaccharide (FOS). The variables observed were: feed consumption, body weight, feed conversion ratio, mortality, and production index. The result showed that the performances of the broiler supplemented prebiotic oligosaccharide extract rumbia fruit (R2) was significantly (P < 0.05) differences between of feed consumption, body weight, and mortality. It is concluded that of prebiotic oligosaccharide extract rumbia fruit were able to decrease the mortality and feed consumption at six week of age.
