Abstract

Nowadays some efforts are being made to reduce obesity by using drugs that aim to reduce appetite of the drug users. However, the use of drugs still has harmful side effects. Endophytic fungi originating from the Dayak onion plant are thought to have secondary metabolites that have potential as anti-obesity. The aims of this study were to determine the compounds produced by endophytic fungi of Dayak onion and to determine the potential components as inhibitors of pancreatic lipase enzymes. Samples of Dayak onions were collected from Palangka Raya using purposive sampling method. Isolation of endophytic fungi was conducted using surface sterilization method and the isolates were grown on PDA. Isolates were characterized and fermented on PDB for 14 days. The selected isolate was analyzed by using GCMS then molecular docking was performed using Autodock Vina and PyRx. The research results showed that there were 7 isolates of endophytic fungi isolated from leaves and roots tissues of Dayak onion. GCMS analysis showed that EBD1 contains 38 compounds. Molecular docking analysis showed that 1,3-Di-O-Acetylpentopyranose, a test ligand, has the closest binding affinity value (-6.6 kcal/mol) to orlistat (control) (-6.8 kcal/mol). Thus, it has the potential as an inhibitor of pancreatic lipase enzyme protein.

Abstract

Uncontrol use of synthetic pesticide causes environmental pollution and leaves its residue in soil and water. The objective of this research was to obtain bacterial isolates capable of producing biosurfactant from Belawan North Sumatera and to observe their biosurfactant activities as well as their potential in degrading of carbosulfan pesticide. Bacteria were isolated using selective medium, Bushnell-Hass Agar (BHA) containing 2% of pesticide with carbosulfan as the active compound. The result showed that all bacterial isolates were able to grow on the medium and consumed carbosulfan as the carbon sourc. The highest cell population was shown by isolate Sp.1 with total count was 7.6×109 CFU/ml. The highest biosurfactant activity was shown by isolate Sp.6 with the volume of emulsion was 5.627 cm3, meanwhile the highest production of biosurfactant shown by Sp.7 with concentration was 54.6 ppm. Two isolates, Sp.1 and Sp.6 were selected for further test to study their abilities in carbosulfan degradation. Both isolates were able to degrade carbosulfan completely after 21 days of incubation.

Abstract

Candidiasis is a fungal infection due to a decrease in the immune system caused by Candida spp. In general, candidiasis is treated with antifungal drugs, but uncontrolled use can result in the emergence of drug resistance and toxicity. Endophytic bacteria have the potential to be biological control agents against various fungal infections including candidiasis. This study aims to determine the antagonistic activity of endophytic bacteria isolated from Dayak onions and the antifungal activity of its cell-free supernatant (CFS) against Candida albicans. Thirteen isolate strains of endophytic bacteria were used in this study. Antagonistic activity was tested using the agar plug diffusion method. Endophytic bacteria that showed antagonistic activity against C. albicans were cultivated in Nutrient Broth media to produce CFS. The antifungal activity of CFS was tested using the Kirby–Bauer disk diffusion method. The results indicated that six isolates of endophytic bacteria from dayak onions have antagonistic activity against C. albicans. CFS from strain CED4 has a strong antifungal activity against C. albicans with a clear zone diameter of 18.5 mm. Further studies are needed to determine the antifungal compounds produced by CED4 isolates for the development of anticandidal.

Abstract

Basal stem rot (BSR) is one of the key contributors to the decline in palm oil production in Indonesia. BSR is caused by the pathogenic plant fungus Ganoderma boninense. Currently, the control of G. boninense growth relies on systemic fungicides. However, systemic fungicides have negative impacts as they can harm natural soil microorganisms. Biocontrol agents present an environmentally friendly alternative for G. boninense management. The objective of this research was to select and identify endophytic bacterial isolates from Dayak onion [Eleutherine bulbosa (Mill.) Urb.] with antagonistic activity against G. boninense. The investigation was initiated with the isolation of 34 endophytic bacterial isolates and G. boninense isolate. The hemolytic capabilities of endophytic bacterial isolates were evaluated on blood agar media. Antagonism assessments were conducted through the dual-culture method, and the inhibition of G. boninense was measured using the percentage inhibition of radial growth (PIRG). The endophytic bacteria exhibiting the highest PIRG values were identified through molecular analysis based on the 16S rRNA gene sequence. Results revealed that 27 isolates demonstrated no ability to hydrolyze blood agar (gamma hemolysis) indicating no pathogenicity. Isolate CED9 demonstrated the highest PIRG value at 70.26%. Genomic identification based on the 16S rRNA gene sequence confirmed that isolate CED9 was classified as Bacillus subtilis. The identification of biocontrol agents from Dayak onion represents valuable information and a potential arsenal for future strategies in mitigating (BSR) disease.

Abstract

Information on macroscopic fungi from Central Kalimantan is still limited compared to other regions in Indonesia. Arboretum Nyaru Menteng, a conservation area located in Central Kalimantan, poses many macrofungi due to its favorable environmental conditions that support the growth of various types of macrofungi. However, the diversity of macroscopic fungi from Arboretum Nyaru Menteng has never been reported. Thus, the current works aimed to provide initial information on the diversity of macroscopic fungi in this conservation area. The exploration was done using the opportunistic sampling method. Fruiting bodies were documented, collected, and identified based on macroscopic characteristics. Four environmental microclimate variables were measured in four random sampling locations: temperature, light intensity, air humidity, and soil acidity. The results confirmed that there were 27 species of macrofungi belonging to 18 genera and 14 families. Polyporaceae was the most dominant family found in this research. Most fungi grew on a dead log while the others were recognized as mycorrhizal fungi and parasites on plants. The environmental measurements showed that Arboretum Nyaru Menteng has an optimal habitat for recorded fungi growth. The record of macrofungi diversity in this research contributes to Indonesia mycoflora, particularly from Central Kalimantan.

Abstract

Fish-based fermented foods are integral to traditional diets across Asia, Africa, and Europe, valued for both their nutritional role and cultural significance. Increasingly, they are also studied for potential functional properties such as probiotic activity and bioactive compounds, yet their global research landscape has not been systematically assessed. This study presents a bibliometric analysis of global research on fish-based fermented foods published between 2015 and 2024. Data were retrieved from the Scopus database and analyzed using the Bibliometrix R package and Biblioshiny interface. A total of 263 documents were identified across 145 sources, authored by 1,150 researchers. The field has shown rapid growth, with an annual publication increase of 27.01% and an average of 28.48 citations per article, indicating strong scholarly visibility. Most contributions originated from East and Southeast Asia, particularly China, South Korea, and Thailand, reflecting the cultural and culinary importance of fermented fish in these regions. Author productivity followed Lotka’s law, with a small group of core researchers driving sustained output. Keyword co-occurrence and thematic mapping revealed dominant clusters around fermented fish sauce, lactic acid bacteria, and microbial diversity, alongside emerging themes related to fatty acids and bacterial communities. Despite these advances, the analysis highlighted notable gaps, including limited international collaboration and underrepresentation of research from Africa and parts of South Asia. These findings suggest that while the field is expanding and diversifying, greater cross-regional engagement and methodological innovation are needed to fully explore the nutritional, functional, and socio-economic dimensions of fish-based fermented foods.
