Abstract

Monosaccharide and disaccharide as carbon sources can affect the production of secondary metabolites. The study aims to determine the effect of variations in carbon sources on growth, physiological stress, and saponin levels of the adventitious roots of Talinum paniculatum Gaerthn. Adventitious roots are subculture in liquid MS medium treated with various sugars: 3% sucrose, 3% glucose, 3% fructose, 3% lactose, 3% maltose, 3% dextrose, sucrose + fructose (1.5% + 1.5%), sucrose + glucose (1.5% + 1.5%), glucose + fructose (1.5% + 1.5%), sucrose + dextrose (1.5% + 1.5%) for 6 weeks. The results of this study show that the 3% fructose treatment produces the highest fresh and dry biomass, which are 1.30 g and 0.23 g compared to the control. The morphology of adventitious roots in the treatment of carbon source variation is not different from the control treatment. The highest MDA (malondialdehyde) levels are found in the sucrose + fructose treatment (1.5% + 1.5%). Meanwhile, the highest proline levels are found in the 3% maltose treatment. Saponin levels analyzed using thin layer chromatography show the data in the form of color intensity and stain area based on ImageJ software analysis. The 3% fructose treatment shows the highest color intensity and stain area compared to the control. Variations in carbon sources affect physiological stress, biomass, and saponin levels of adventitious roots of T. paniculatum, but do not effect on root morphology.

Abstract

The red list of the International Union for the Conservation of Nature and Natural Resources (IUCN) reported Castanopsis argentea as an endangered species. Studies about autecology on its natural habitat become important to perform species conservation. This study aimed to analyze the population structure, distribution pattern, and environmental factors that influence the presence of C. argentea in the Telaga Warna Nature Reserve. Data was collected in September 2020 by making 21 plots with a single plot. The purposive sampling method was used based on C. argentea representatives to determine plot location. Measurement of environmental factors, including soil sampling was carried out on each plot. Population structure was analyzed based on plant density, and Morisita index determined the distribution pattern. Environmental data were analyzed using PCA with Minitab 19 programs. Our field observation showed that C. argentea seedling has the highest density (1071 ind/ha) and decreased in the mature phase. C. argentea was found to have a clumped distribution pattern with an Id value of 1.03. PCA analysis showed differences in environmental factors that were thought to influence the presence of C. argentea individuals in four growth phases. The highest population structure of C. argentea was found in the growth phase of seedlings and saplings at an altitude of 1400 m asl. The spread population distribution of C. argentea was clumped. The influences of environmental variables on the existence of C. argentea were Mg, Ca, CEC, pH, and soil moisture.

Abstract

Neobalanocarpus heimii (Cengal) is from the family Dipterocarpaceae. It is a long-lasting wood that is also one of the most robust timbers in the world. This species is native to Peninsular Malaysia and southern Thailand. In this study, the Cengal heartwood was studied concerning the amount of water extractive content with antifungal properties from the Neobalanocarpus heimii. The dilution method was used to test the antifungal properties. Wood meals samples were subjected to the sequential extractive beginning with hexane followed by dichloromethane, methanol and water. The extracts were collected and underwent evaporation by using rotary evaporator to obtain pure crude extract. The antifungal activities were determined using agar dilution method. Two selected fungi Trametes versicolor (T. versicolor) and Coniophora puteana (C. puteana) were used. The antifungal index (%) which compares the diameter of the growth zone for the experimental plate and control plate was calculated. The total percentage of yield from Neobalanocarpus heimii was 0.28%. The highest antifungal index obtained for Trametes versicolor (T. versicolor) was 81.22%, while C. puteana was 43.24%. The crude extracts from Neobalanocarpus heimii were effective in inhibiting the growth of Trametes versicolor and Coniophora puteana.

Abstract

Diabetes mellitus is a disease related to hyperglycemia and insulin resistance that can lead to the outcome of chronic liver diseases such as nonalcoholic fatty liver disease (NAFLD). Red betel leaves are known as traditional plants that have anti-hyperglycemic potential. This study aimed to investigate the effect of ethanolic extract of red betel leaves nanoparticle (RbL-Nps) on the liver and hepatic insulin receptor’s (INSR) expression in diabetic rats. Thirty rats were included in this study and further divided into five groups containing six rats each. Group I (GI) comprised of the normal rats; while group II (GII), III (GIII), IV (GIV) and V (GV) comprised of diabetic rats induced by streptozotocin (STZ) at dose of 45 mg/kg bw and nicotinamide (NA) at dose of 110 mg/kg bw, intraperitoneally. Group I and II were treated with 0,5% Na-CMC orally.  Group III, IV and V were given the oral administration of RbL-Nps at the doses 30, 60, and 90 mg/kg bw diluted in 0,5% Na-CMC, respectively. All groups were treated once daily and subsequently euthanized after 28 days. Liver tissues were collected for immunohistochemistry method to see the INSR expression and haematoxylin-eosin (HE) staining. Result in this study revealed that INSR expression on the GI, GIII and GIV were significantly higher compared to that on the GII (p < 0.05). On the other hand, there were no significant differences on the INSR expression between GV and GII (p > 0.05). Histologically, liver tissues retrieved from GII showed severe vacuolic and necrotic hepatocytes with dilatated sinusoid. Mild vacuolic and necrotic hepatocytes were observed from GV. There were no pathological changes observed in the liver tissues retrieved from GI, GII, and GIV. We concluded that RbL-Nps improved the liver condition of diabetic rats at doses of 30 and 60 mg/kg bw, but not at doses of 90 mg/kg bw.

Abstract

Mushrooms have been considered an important part of human life due to their various benefits and potential. In Indonesia, many indigenous people get used to foraging and using wild mushrooms as part of their daily lives. To date, there was no update following prior local name checklist of wild mushroom and their uses in Indonesia. Thus, this review aims to provide the latest work on that information known so far in the country. A literature review was focusing on available publications containing the local names and the use of wild mushrooms in Indonesia. 107 mushrooms in total are known to have 170 local names with 36 of them having more than 1 indigenous name. Some of them: Coprinus spp., Polyporus spp., Schizophyllum commune, Scleroderma spp., Termitomyces spp., and Trametes spp. are known to have 5 local names for each region and ethnicity that uses them. 50 species of mushrooms in total are used as food and traditional medicine. The information was derived from 8 provinces and 8 tribes, of which West Kalimantan Province and Javanese ethnicity contributed to the highest number of it. The number of local names is expected to increase as more investigations are conducted in the near future.

Abstract

The marine environment continues to surprise us by producing novel bioactive substances with a wide range of benefits for humans. Materials and Methods: Marine bioluminescent bacteria Photobacterium leiognathi was isolated from pony fish, Secutorruconius which was confirmed with microscopic and molecular characterization. The secondary metabolite of the isolated bacteria was extracted with dichloromethane. The chemical fingerprinting of the isolated metabolite was analyzed through TLC, FT-IR, and HPLC. The nature of the compound present in the metabolite was identified in the gas chromatography-mass spectrometry analysis (GC - MS). The isolated extract was investigated for its antibacterial property against 10 human pathogenic bacteria and also its antioxidant activity using different assays such as 1, 1-Diphenyl-2-picrylhydrazyl, Phosphomolybdenum, Metal chelating, Hydroxyl radical scavenging and hydrogen peroxide scavenging activity. Results: The Presence of functional groups including phenols, sugars, and amino acids in the extracts were identified by TLC. Totally, nine peaks were obtained for the crude extract through the FTIR spectrum range of 400 to 4000 cm-1 for the active sample. The DCM extract showed a broad spectrum of antibacterial activity against the six human bacterial pathogens. Secondary metabolites from the bioluminescent bacteria, P. leiognathi, have strong antioxidant properties. These results will be instrumental in developing novel products with biosensors and bio-imaging applications using P. leiognathi.

Abstract

The enormous potential of marine resources possessed by Banda Aceh Province is expected to be utilised optimally. Accuracy in marine fish resource identification is a critical requirement to support their utilisation and preservation in Banda Aceh Province. In this study, a molecular identification approach was carried out in addition to conducting a morphological identification, commonly used by several scientists. The results were 47 COI sequences generated representing 33 genera, 19 families, and five orders. From the resulting COI partial sequences, there is one potential haplotype from the Scombridae family (Auxis thazard), two potential haplotypes from the Carangidae family (Elagatis bipinnulata and Decapterus macarellus), and two potential haplotypes from the Serranidae family (Variola albimarginata and Cephalopholis sonnerati). This study is essential for fisheries biological studies and other fisheries studies to support the sustainable utilisation of marine fisheries potential in Banda Aceh.

Abstract

Lactic Acid Bacteria (LAB) synthesize various metabolites during their growth phase and are Generally Recognized as­­ Safe (GRAS) and Qualified Presumption of Safety (QPS). Ribosomally synthesized Antimicrobial Peptides (AMP) or Bacteriocins from the genera of Lactic Acid Bacteria and other prokaryotic genera are cationic, heat-stable, amphiphilic and the membrane permeabilizing peptides built with an excess amount of lysyl and arginyl residues. Antimicrobial compounds produced by LAB depend on the physical and biological conditions of microbial culture. Different classes of bacteriocin are produced by both Gram-positive and Gram-negative bacteria. The production of bacteriocin is influenced by various environmental factors. Bacteriocin has a wide variety of applications in various fields.   The application spectrum of bacteriocins can be expanded in various domains such as food processing, biomedical, and personal care due to the increase in the number of newly discovered bacteriocins. Bacteriocins acquire a wide spectrum of antimicrobial activity with minimal level of cytotoxicity. In addition, bacteriocins were studied for their anticancer activity against different cancer cell lines. Selective binding of bacteriocins (cationic) towards cancer cells (anionic) increases the cytotoxicity of cancer cells. Bacteriocin peptides initiate necrosis by communicating with the cell surface which selectively targets and kills the cells with tumor formation and does not cause any damage to the normal healthy cells. In this review, the bacteriocins synthesized from lactic acid bacteria along with their interaction with cancer cell lines and other applications are discussed along with a few examples of other bioactive compounds produced by LAB.
