Abstract

Endophytic bacteria are bacteria that carry out symbiosis with host plants without causing disease without the host plant. Some endophytic bacteria found in plants are able to produce potential compounds as antioxidants by producing the enzyme SOD (Super Oxide Dismutase). This research aims to determine the results of endophytic bacterial fermentation from the leaves of the breadfruit plant (Artocarpus altilis). This research began with the identification of endophytic bacteria, then continued with the extraction of the SOD enzyme by adding PBS and centrifuging. Purification of the SOD enzyme was carried out using the ammonium sulfate precipitation method. Determination of total protein content using the Lowry method. SOD activity was measured by measuring the percent inhibition value using the Superoxide Dismutase Activity Assay Kit WST-1. The results of the research showed that the isolated bacteria had morphological characteristics in sequence from colony shape, color, size, elevation, edges, cell shape and Gram type for AL 4 bacteria Filamentous, white, medium, flat, Rhizoid, coccus, Gram +, citrate -, Catalase -, for IL11 bacteria Irregular, white, large, flat, entire, bacilli, and Gram +, citrate +, Catalase +. The extraction results from the crude extract produced a sediment weight of 2,915 g for AL4 and 1,653 g for IL11. The total protein content of the crude extract and 30% ammonium sulfate precipitation for isolate AL4 was 1.74 mg/mL and IL11 1.79 mg/ml. Then the percent inhibition value for isolate AL4 with a concentration of 20% was 64.02% and a concentration of 80% was 71.43%.

Abstract

Staphylococcus aureus is a gram-positive bacterium that is part of the normal flora of human skin and mucous membranes. Staphylococcus aureus can cause infectious diseases. Cherry leaves are known to contain active compounds with antibacterial potential. The purpose of this study was to determine the antibacterial activity of cherry leaf extract fractions against Staphylococcus aureus bacteria, determine the MIC and MBC values, and detect the active fraction content. This study used an extraction method by maceration using 70% ethanol solvent and fractionation of cherry leaf extract using n-hexane, ethyl acetate, and water solvents. The disk diffusion method used a dilution series of 50%; 25%; 12.5% to obtain the most active fraction activity. The dilution method to determine the effectiveness of the concentration of the diffusion test with a dilution series of 50%; 25%; 12.5%; 6.25%; 3.12%; 1.56%; 0.78%; 0.39%. Data in the diffusion test were analyzed using SPSS to obtain the best activity. The normality test used the Shapiro Wilk test and homogeneity with Levene Statistic, then continued with the One Way ANOVA test. The results of the study showed that the most active extract fraction tested by the diffusion method was in the ethyl acetate fraction with a diameter of 26.95 mm. The ethyl acetate fraction tested by the dilution method had a MBC value of 6.25%. The ethyl acetate fraction was tested for content detection by Thin Layer Chromatography containing flavonoids, tannins, saponins, and alkaloids.

Abstract

Buah belimbing wuluh memiliki kandungan senyawa pada yaitu flavonoid, tanin, saponin, steroid/triterpenoid dan alkaloid yang berfungsi sebagai antibakteri. Penelitian ini bertujuan untuk menguji aktivitas antibakteri fraksi n-heksan, etil asetat dan air dari ekstrak etanol buah belimbing wuluh terhadap pertumbuhan bakteri Staphylococcus aureus ATCC 25923; mengetahui fraksi teraktif dan Konsentrasi Bunuh Minimum (KBM) dari buah belimbing wuluh terhadap pertumbuhan bakteri Staphylococcus aureus ATCC 25923. Buah belimbing wuluh diekstraksi menggunakan metode maserasi dengan pelarut etanol 96%. Fraksinasi dari ekstrak buah belimbing wuluh dengan pelarut n-heksan, etil asetat dan air. Uji aktivitas antibakteri ekstrak dan fraksi dari ekstrak etanol buah belimbing wuluh terhadap Staphylococcus aureus dilakukan dengan metode difusi pada konsentrasi 20%, 10%, dan 5%, sedangkan penentuan Konsentrasi Hambat Minimum (KHM) dan Konsentrasi Bunuh Minimum (KBM) dari fraksi teraktif dengan metode dilusi pada konsentrasi 50%; 25%; 12,5%; 6,25%; 3,12%; 1,56%; 0,78%; 0,39%. Data diameter zona hambat yang diperoleh dari hasil uji difusi dianalisis statistik menggunakan metode one way ANOVA. Hasil penelitian menunjukkan bahwa ekstrak dan fraksi buah belimbing wuluh memiliki aktivitas antibakteri terhadap Staphylococcus aureus ATCC 25923. Fraksi etil asetat buah belimbing wuluh dengan konsentrasi 20% memiliki aktivitas antibakteri teraktif dengan rata- rata diameter zona hambat sebesar 26,32 mm. Konsentrasi Bunuh Minimum (KBM) fraksi etil asetat terhadap bakteri Staphylococcus aureus ATCC 25923 sebesar 12,5%.

Abstract

Moringa leaves (Moringa oleifera) and guava leaves (Psidium guajava L.) contain antibacterial compounds such as alkaloids, tanins, saponins, and flavonoids that effectively inhibit Escherichia coli bacteria. This study aims to determine the antibacterial activity of the combination of both extracts using dilution, diffusion, and paper tape methods with concentrations of 100%, 50%, 25%, 12.5%, 6.25%, 3.1%, 1.5%, and 0.7%, ciprofloxacin as a positive control and 10% DMSO as a negative control. The results of the dilution test showed that a concentration of 12.5% ​​was able to kill Escherichia coli bacteria, the 1:2 combination diffusion test provided the largest inhibition zone, indicating optimal antibacterial effectiveness. and the paper tape test showed an additive pattern indicating that the two extracts supported each other in inhibiting the growth of these bacteria
