Abstract

Endophytes represent a complex community of microorganisms colonizing asymptomatically internal tissues of higher plants. Several reports have shown that endophytes enhance the fitness of their host plants by direct production of bioactive secondary metabolites. This study investigated the antibacterial activity of endophytes fungi IFKBM04 isolated from Swietenia mahagoni L. and identified macroscopic and microscopic characteristics of endophytic fungi. Based on the results of macroscopic and microscopic identification compared with the literature to determine the general characteristics of the sample. The results of this morphological identification showed that the sample of mahogany bark isolate (Swietenia mahagoni L.) code IFKMB-04 had similarities with the genus Saccharomyces sp.

Abstract

The Aloe vera plant, also known as the Lidah buaya plant, has antibacterial properties due to its secondary metabolites, which include alkaloids, flavonoids, tannins, and saponins. In this study, endophytic fungi from Lidah Buaya (Aloe vera) were isolated against bacteria that cause gastrointestinal tract infections using TLC-Bioautography and Agar Diffusion. In this study, 7 isolates of endophytic fungi were obtained, one of which was IFLB 1 which had potential as an antibacterial, purification of the endophytic fungi was carried out and then macroscopic examination was carried out on the fungi to see the colonies formed. After that, a screening test was carried out for isolates of endophytic fungi. Then the isolates that gave the best activity were reproduced and continued with the fermentation process for 14 days. The extraction results were then evaporated to obtain a thick extract and a Thin Layer Chromatography (TLC) Identification test was carried out in which the eluent used was chloroform: methanol (5:1). Then continued the TLC-Bioautographic Antibacterial Activity Test on Escherichia coli, Salmonella thypi, Shigella dysentriae and Vibrio cholerae bacteria and obtained 2 active spots with Rf1 = 0.78 and Rf2 = 0.30. While the results of testing the antibacterial activity using the Agar Diffusion method obtained the largest diameter of the inhibition zone at a concentration of 4% for Escherichia coli with an inhibition zone diameter of 15.80 mm, Salmonella thypi with an inhibition zone diameter of 14.90 mm, Shigella dysentriae with an inhibition zone diameter of 13 .85 mm and Vibrio cholerae with an inhibition zone diameter of 14.70 mm

Abstract

Areca nut (Areca catechu L.) seeds has antibacterial properties due to their alkaloid, flavonoid, tannin, saponin, and polyphenol compounds. Binahong leaves (Anredera cordifolia (Ten.) Steenis) contain flavonoids, polyphenols, saponins, and alkaloids that also act as antibacterial agents. This study aimed to assess the antibacterial activity and synergistic effects of combining extracts from areca nut and binahong leaves against Propionibacterium acnes. The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) of P. acnes were evaluated for the ethanol extracts of areca nut and binahong leaves. The MIC and MBC values 400 ppm and 1.600 for extract ethanol single areca nut and 50.000 ppm and 100.000 ppm for binahong leaves. The MIC and MBC values for the combination 400/12.500 ppm and 1.600/781,25 ppm for areca nut and 50,000/800 ppm and 100,000/100 ppm for binahong leaves, respectively. The synergy between the two extracts was determined using the Fractional Inhibitory Concentration Index (FICI). The FICI value of 1. P. acnes indicates an indifferent effect (1 < FICI ≤ 4).
