“…Beberapa penelitian telah dilakukan pada sifat antimikroba Elaeis guineensis terhadap infeksi manusia. Elaeis guineensis ditemukan memiliki aksi antibakteri terhadap E. coli, Pseudomonas aeruginosa, dan Staphylococcus aureus 6 , namun, potensi bakteri endofit dari daun kelapa sawit untuk menghambat bakteri patogen belum pernah dilaporkan sebelumnya. Tujuan dari penelitian ini adalah untuk mengetahui aktivitas antibakteri bakteri endofit yang diisolasi dari daun kelapa sawit, sehingga dapat menjadi referensi di masa depan sebagai salah satu sumber antimikroba.…”

Mikroorganisme endofit adalah mikroorganisme yang terdapat dalam jaringan tanaman dan memiliki kemiripan sifat senyawa bioaktif dengan tanaman inangnya. Daun kelapa sawit diketahui memiliki aktivitas antibakteri, tetapi penelitian mengenai aktivitas antibakteri bakteri endofitnya belum pernah dilaporkan. Tujuan penelitian ini adalah mengisolasi bakteri endofit dari daun kelapa sawit serta menentukan aktivitas antibakteri terhadap Escherichia coli dan Staphylococcus aureus. Delapan isolat bakteri endofit berhasil diisolasi dari daun kelapa sawit. Satu isolat termasuk bakteri Gram negatif dan tujuh isolat adalah bakteri Gram positif. Analisa morfologi menunjukkan satu isolat berbentuk basil dan yang lain berbentuk kokus. Uji antibakteri menunjukkan satu isolat (IDS18) menunjukkan aktivitas antibakteri yang kuat terhadap S.aureus dengan zona hambat 13 mm, tetapi tidak menunjukkan aktivitas antibakteri terhadap E. coli. Sementara lima isolat yaitu IDS1, IDS10, IDS11, IDS14 dan IDS16 menunjukkan aktivitas yang lemah terhadap E.coli, tetapi tidak memiliki aktivitas terhadap S.aureus. Hasil penelitian menunjukkan bahwa bakteri endofit daun kelapa sawit berpotensi sebagai penghasil senyawa antibakteri. Diperlukan penelitian lebih lanjut mengenai optimasi produksi senyawa bioaktif antibakteri serta karakterisasinya.

Nosemosis is one of the most devastating diseases of Apis mellifera (Honey bees) caused by the single-celled spore-forming fungi Nosema apis, N. ceranae and N. neumanii, causing a severe loss on the colony vitality and productivity. Fumagillin, a MetAP2 inhibitor, was a certified treatment for controlling nosemosis, nevertheless, due to its deleterious effects on honey bees and humans, it is prohibited. So, searching for novel biological agents with affordable selectivity to target Nosema species infecting Apis mellifera, with nil toxicity to bees and humans is the main objective of this study. Nosema species were isolated from naturally infected honey bees. The methanolic extracts of Acacia nilotica, Elaeis guineensis, and Catharanthus roseus were tested to selectively control the growth of Nosema spp of honeybees. The spores of Nosema species were molecularly and morphologically identified. Among the tested plant extracts, the methanolic extracts (0.1%) of A. nilotica had the most activity towards Nosema spp causing about 37.8 and 32.5% reduction in the spores’ load at 5- and 9-days post-infection, respectively, compared to the untreated control. At 0.1%, the A. nilotica methanolic extract exhibited the highest inhibitory effect for Nosema spores, without any obvious bee mortality. Catharanthus roseus displayed a reduction of spores by 27.02%, with bee mortality rate of 27.02%. At 1% for 5 dpi, the A. nilotica extracts led to 18.18% bee mortality, while the C. roseus extracts resulted in 100% mortality, as revealed from the toxicity and quantification bioassays. So, the extracts of A. nilotica and C. roseus had a significant effect in controlling the N. apis and N. ceranae titer compared to the infected untreated control at both time points. The titer of N. apis and N. ceranae was noticeably decreased by more than 80% and 90%, in response to A. nilotica, compared to the control. From the metabolic profiling by GC–MS analysis, the most frequent active compounds of A. nilotica were 2,4,6-trihy-droxybenzoic acid, 1,2-dihydroxybenzene, myristic acid, and linoleic acid. These compounds were analyzed in silico to assess their binding affinity to the ATP binding protein, methionine aminopeptidase and polar tube protein of Nosema species as target enzymes. The compound 2,4,6-trihydroxybenzoic acid had the lowest energy to bind with ATP binding protein, methionine aminopeptidase and polar tube protein of Nosema, followed by 1,2-dihydroxybenzene and myristic acid, compared to fumagilin. So, from the experimental and molecular docking analysis, the extracts of A. nilotica had the highest activity to attack the cellular growth machinery of Nosema species without an obvious effect to the honeybees, ensuring their prospective promising application.

Vibrio harveyi and Vibrio parahaemolyticus are species of the Vibrio genus that often cause disease and mass mortality in crustaceans. If not handled quickly and appropriately, these diseases can cause considerable losses to farmers. Therefore, it is necessary to find a solution with safe and environmentally friendly disease prevention technology using natural ingredients, among others from plants, namely oil palm. Some parts of oil palm, namely leaves, fronds, fibres and oil palm pulp, which are palm waste, contain antibacterial compounds. This study aimed to assess the antibacterial activity of palm waste extracts, namely pulp, leaves, fronds and fibres using n‐hexane, ethyl acetate, chloroform, ethanol and water maceration solvents against pathogenic bacteria V. harveyi and V. parahaemolyticus, and identify active compounds contained in palm waste. The results of the research are expected to produce innovative and sustainable solutions to control diseases in shrimp farming, contribute to the development of a sustainable fishing industry and open up the potential for utilizing palm waste as a value‐added resource in the field of aquatic health. The results of observations on antibacterial activity tests and identifying the content of palm waste extract compounds were analysed descriptively displayed in the form of figures, tables and graphs. The results showed that palm waste extracts (pulp, leaves, fronds and fibres) with ethyl acetate and ethanol maceration solvents had very strong antibacterial potential, namely 20.14 ± 0.31 mm–25.52 ± 1.42 mm on V. harveyi bacteria and 20.41 ± 0.55 mm–25.00 ± 0.51 mm on V. parahaemolyticus bacteria. Palm extracts with n‐hexane (>20 mm) and chloroform solvents generally have strong category antibacterial potential (10–20 mm), and palm extracts in water solvents have medium category potential (5–10 mm) against V. harveyi and V. parahemolyticus bacteria. The results of phytochemical tests on palm waste extracts with ethyl acetate and ethanol maceration solvents contain bioactive compounds of flavonoids, saponins, polyphenols and alkaloid tannins, steroids and triterpenoids. Palm extracts with n‐hexane and chloroform solvents generally contain saponins, alkaloids, steroids and triterpenoids, while palm waste extracts with water solvents contain saponins.
