The success of oil palm tissue culture is constrained by the microbes contaminating cultures in the laboratory. Accurate identification of contaminant species leads to the right strategies for solving the contamination problem. This research was done to identify contaminant species at the Indonesian Oil Palm Research Institute Tissue Culture Laboratory at its stages by using DNA barcodes. Bacteria identification was done by 16S rRNA sequencing, while fungi identification was done by ITS region sequencing. Preliminary results showed that bacteria and fungi were identified in the laboratory’s stages of the tissue culture process. Four species were identified in the dark room, two in the light room, and four in the advanced light room. The identified bacteria were Bacillus subtilis, Streptococcus parasuis, Priestia megaterium, and Bacillus sp. The identified fungi were Tritirachium candoliense, Penicillium citrinum, Irpex laceratus, Aspergillus reticulatus, and Perenniporia tephropora. More data is needed to determine the right strategies to control the contamination problem.

“…In therapeutic applications, endophytic fungi act as antibacterial agents (Deshmukh et al, 2015;Gagana & Shivanna, 2020;Pansanit & Pripdeevech, 2018). For instance, the antibacterial activity of the endophyte Tritirachium oryzae isolated from Syzygium malaccense contains 2-(4-hydroxyphenyl) -4-methoxytetrahydrofuran-3-ol (Hapida et al, 2022); Fusarium verticillioides, isolated from the stem bark of S. jambos, contains 3-hydroxy-4-(hydroxy(4-hydroxyphenyl)methyl)dihydrofuran-2-on ; and Penicillium brefeldianum from the root bark of Syzygium zeylanicum contains phydroxybenzaldehyde (Syarifah et al, 2021).…”

Endophytic fungi isolated from medicinal plants have high diversity and the secondary metabolites produced have biological activity. Endophytic fungi isolated from medicinal plants have been the subject of many studies on their diversity and biological activity, one of which is jambu mawar (Syzygium jambos (L.) Alston). S. jambos has long been used as a traditional medicine to treat infections caused by pathogenic bacteria in many parts of the world, including South Sumatra. This study purposed to explore the diversity of endophytic fungi isolated from the branches of S. jambos, the antibacterial activity of endophytic fungi extracts, the determination of the structure of the compounds, and the activity of the active compounds of the selected endophytic fungi. Observations of the morphological characteristics of endophytic fungi were macroscopically and microscopically. The endophytic fungal extracts were then tested for antimicrobial activity against test bacteria Staphylococcus aureus, Bacillus subtilis, Salmonella typhi, and Escherichia coli using the Kirby-Bauer paper disk diffusion method. Isolation of pure compounds using a gravity chromatography column, the determination of the structure of the compound is determined based on 1H-NMR, 13C-NMR, HMQC, and HMBC spectroscopy. Four endophytic fungi, code SJC1–4, were isolated from a branch of S. jambos. The results of macroscopic and microscopic morphological characterization showed three genera of Botryosphaeria, Trichothecium, and Aspergillus. The endophytic fungal isolate SJC1 exhibited strong activity against Gram-positive bacteria and moderate activity against Gram-negative bacteria, while SJC2–4 showed moderate activity against the four bacteria. Molecular identification of SJC1 revealed that it was Botryosphaeria mamane. Isolation of SJC1’s pure compound yielded compound 1, which was identified as 5-acetyl-6-hydroxy-3-methyl-2H-pyran-2-one. This compound is thought to have antibacterial properties.

“…One of the key factors influencing development of novel drugs is natural compounds produced by endophytic fungus (Ahmed et al, 2023;Elawady et al, 2023;Elfita et al, 2022a;Hapida et al, 2022;Stelmasiewicz et al, 2023;Tammam et al, 2023;Zhu et al, 2023). The bulk of secondary metabolites generated by endophytic fungus have a different chemical structure, according to various studies Liu et al, 2023;Oktiansyah et al, 2023c;Rodrigo et al, 2021;Song et al, 2023;Stelmasiewicz et al, 2023).…”

Salam (Syzygium polyanthum) is a plant that is often used by Indonesian people as traditional medicine. The leaves are consumed to treat various diseases. This study reports the endophytic fungi found from S. polyanthum leaves and its secondary metabolites. Endophytic fungi species were determined through morphological and molecular identification. Potato Dextrose Broth medium was used for the cultivation process and ethyl acetate was used as a solvent for the extraction process. Antioxidant tests was carried out by using the DPPH method. Chromatographic techniques were used for the isolation of secondary metabolite and spectroscopic analysis was carried out to identify their chemical structures. The results of morphological and molecular analysis showed that the sample was Daldinia eschscholtzii. The secondary metabolite obtained from this endophytic fungus was idetified as fonsecinone A with good antioxidant activity. The secondary metabolite have the potential to become a source antioxidants through further research.
