Abstract

Balinese Hindu community cannot be separated from plant in their life. The information on plant species and how to utilize them are easy to find but limited information about the potency of flowers in the Balinese Hindu community. Flowers have a meaning as sincerity, a symbol of Sang Hyang Widhi, the valour, and also have mythological values. This research aimed to determine the species of flowering plants that are often used for ceremonial and understand the meaning, the cultural conception related to conservation education. The study was carried out in four locations in Tabanan Regency (Baturiti, Penebel, Marga, and Tabanan). Data were collected using an interview with purposive sampling. Data analysis based on the value of Relative Frequency (FR) which is indicated plant most widely used.  A total of 36 species of flowers are used in traditional Hindu religious ceremonies, of which 29 species are cultivated plants and 7 species are still wild. There are ten of plants which have high FR value, such as: Cananga odorata (FR 0.069), Impatiens balsamina (FR 0.069), Hydrangea macrophylla (FR 0.069), Plumeria acuminata (FR 0.069), Tagetes erecta (FR 0.069), Magnolia champaca (FR 0.069), Gomphrena globosa / bunga ratna (FR 0.047), Gardenia jasminoides / jempiring (FR 0.039), Nymphaea spp./ tunjung (FR 0.030), and Hibiscus rosa-sinensis L./ pucuk (FR 0.030). This research revealed the role of flower in Hindu ceremony and describe the strategic plant conservation due to culture of Balinese Hindu community. Finally, this research expected to documented local knowledge about flowers used as Hindu religious ceremonies, to provide an understanding of the meaning and conceptions of culture related to conservation education.

Abstract

This research has been carried out with a view to induce rooting and  plantlet formation, followed by acclimatization.  Micro shoots of sugarcane cv. PS 881 were cultured on Murashige and Skoog medium supplemented with different types and concentration of auxins for root induction. This research conducted experimentally using a split-plot design. The main plots were three types of auxins, which consisted of IAA, IBA, and NAA. The subplots were auxin concentrations with four levels, i.e. 0 μM, 5 μM, 10 μM, and 15 μM. Significantly faster root emergence time and higher number of roots observed in the Murashige and Skoog basal medium supplemented with 10 μM NAA. The best root length obtained in the Murashige and Skoog basal medium supplemented with NAA 0 μM. Plantlets derived from NAA 10 μM treatment showed the best performance during acclimation with a 100% survival rate. NAA at a concentration of 10 µM considered to be the best treatment in  plantlet formation and acclimatization of sugarcane cv. PS 881. This study showed that the use of MS medium with 10 uM NAA is able to increase the growth of PS 881 sugarcane plantlets. The results of this study can increase the availability of high quality seedlings and increase national sugar production.

Abstract

Flamboyant flower (Delonix regia) extract can increase proliferation and differentiation rates of mesenchymal stem cells (MSCs) into specific cells such as bone, nerve, and fibroblast cells. The extract possess metabolic compounds that may act as antibiotics, anti-inflammatory, antimicrobial, diuretic, anthelmentic, astringent, leucorrhoea, and potentially increase the body's metabolism normally. This study aimed to investigate expression level of alkaline phosphatase (ALP) by mice MSCs treated with flamboyant flower extract in vitro. Here, mice bone marrow cell cultures were treated with flamboyant flower extracts of 0.6 mg/ml (P1), 0.7 mg/ml (P2), 0.8 mg/ml (P3), and 0.9 mg/ml (P4). Untreated cell culture was used as negative control (P0). Expression of ALP gene was measured by RT-qPCR method. The results showed that mice mesenchymal stem cell could differentiate into bone, nerve, and fibroblast cells. The addition of flamboyant flower extract ranged from 0.6-0.9 mg/ml significantly (p<0.05) influenced the expression of ALP by differentiating MSCs. The highest expression was found at the stem cells treated with flamboyant flower extract of 0.8 mg/ml, 0.13 times compared with control. In conclusion, flamboyant flower extracts treatment might increase the expression of ALP in differentiating MSCs.  This information can be used as a basis for finding an appropriate biomarkers for tracking the differentiation and profileration of tissue originated MSCs induced by extracts of medicinal plants.

Abstract

Bacteria BSR 2, Pseudomonas alcaligenes (BSR 3), Brevibacillus parabrevis (BSR 8), Brevibacillus sp. (BSR 9), isolated from termite gut and Bacillus licheniformis (BSA B1) isolated from milkfish gut have been known to possess celluloytic activity. However, their lignolytic ability has not been known. This study aimed to determine the lignolytic ability of bacteria isolated from termit (Coptotermes sp.) and milkfish (Chanos chanos Forsskal, 1775) guts and their enzymes characterization. The qualitative test was done through the spot test method, while quantitative assay was performed spectrophotometrically at 335 nm to calculate vanillin concentration. The isolates were grown in Lignin Mineral Medium, then the optical density (OD620) were measured every 24 hours for 5 days using spectrophotometer to determine their growth profile and the best isolation time of the lignolytic enzyme. Based on results, the best lignolytic enzyme isolation time for strains Bacillus licheniformis (BSA B1) and BSR 2 were 5 days, yielding lignolytic enzyme activity of 0.961 ± 0.168 U/mg and 2.176 ± 0.088 U/mg respectively,  while strains Pseudomonas alcaligenes (BSR 3), Brevibacillus parabrevis (BSR 8), and Brevibacillus sp. (BSR 9) were 4 days, yielding of 1.206 ± 0.045 U/mg, 1.162 ± 0.191 U/mg, and 0.896 ± 0.108 U/mg, respectively. The strain BSR 2 showed the highest lignolytic activity compared to other strains. The optimum temperature for lignolytic enzyme activity of BSR 2 was 30 ℃ and the optimum pH was 7. The lignolytic enzyme activity showed that these bacterial isolates can be a chance to be used as new alternative lignolytic enzyme source in commercial bioconversion process.

Abstract

Carotenoids are fat-soluble pigments that have various benefits in health and beauty. The demand and market of carotenoids are increasing; thus, the faster and cheaper biological production of these pigments using microorganisms is desired. In this study, the optimum medium pH and nitrogen concentration for carotenoid production by Rhodosporidium (R.) paludigenum using orange peel extract as substrate were determined. The soluble sugars from orange peels were extracted using distilled water at 100 °C. The yeast inoculum was cultivated in Yeast Peptone Dextrose (YPD) media before fermentation. The independent variables in the fermentation factorial design included initial medium pH (5; 6; and 7) and nitrogen concentration (0; 1; and 1.75 g/L urea in the medium). The decrease in reducing sugar concentration and the increase in biomass dry weight during fermentation demonstrated carbon source consumption by R. paludigenum for growth and carotenoid production. On the sixth day of fermentation (D6), the culture was harvested for the total carotenoid extraction and determination. The highest total carotenoid yield (107.63 µg/g) was achieved by the treatment group with an initial medium pH of 6 without nitrogen supplementation. This result indicated the orange peel extract potential as a substrate for carotenoid production using R. paludigenum as a workhorse. This was the first reported research in natural carotenoid generation using R. paludigenum (strain InaCC Y-236) locally isolated in Indonesia as the producer and orange peel extract as the substrate. Thus, this research would enrich the microbial carotenoid exploration and waste valorization to value-added products at the same time. The study can then be developed further and upscaled for industrial applications.

Abstract

Halogenated compound such as 2,2-dichloropropionic acid is known for its toxicity and polluted many areas especially with agricultural activities. This study focused on the isolation and characterization of the bacterium that can utilise 2,2-dichloropropionic acid from palm oil plantation in Lenga, Johor and in silico analysis of putative dehalogenase obtained from NCBI database of the same genus and species. The bacterium was isolated using an enrichment culture media supplemented with 20 mM 2,2-dicholoropropionic acid as a carbon source.  The cells were grown at 30˚C with cells doubling time of 2.00±0.005 hours with the maximum growth at A680nm of 1.047 overnight. The partial biochemical tests and morphological examination concluded that the bacterium belongs to the genus Staphylococcus sp.. This is the first reported studies of  Staphylococcus sp. with the ability to grow on 2,2-dichloropropionic acid. The genomic DNA from NCBI database of the same species was analysed assuming the same genus and has identical genomic sequence.  The full genome of Staphylococcus sp. was screened for dehalogenase gene and  haloacid dehalogenase gene was detected in the mobile genetic element of the species revealed that the dehalogenase sequence has little identities to the previously reported dehalogenases.The main outcome of the studies suggesting an in situ bioremediation can be regarded as a natural process to detoxify the contaminated sites provided that the microorganisms contained a specialised gene sequence within its genome that served the nature for many long years. Whether microorganisms will be successful in destroying man-made contaminants entirely rely on what types of organisms play a role in in situ bioremediation and which contaminants are most susceptible to bioremediation.

Abstract

Palm sugar solution diets that were offered to the Lorikeets contain  high energy, low protein and rich in amino acids similar to nectar. The major components of palm sugar are sucrose, which has a sweet taste. The Lorikeets  can detect energy-rich from the sweet taste of the feed. The aim of the study was to determine the influence of sweetness level and amino acid composition in palm sugar solution diets on feed intake of T. haematodus. The research method was completely randomized design arranged in a factorial with two factors. The first factor consisted of 4 types of palm sugars, i.e.   aren, coconut, siwalan/palmyra, and nipah sugar with a different degree Brix in 13.5º, 14.0º, 14.5º, and 15.0º Brix.While the second factor consisted of two treatments, with and without the addition of the commercial baby biscuit. The results showed that the feed intake of Siwalan sugar was significantly higher than the other palm sugar solution diets. Siwalan sugar solution diet has high sweetness level, sucrose content and essential amino acid Lysine. This study provides the new information regarding the sweetness level of palm sugar and amino acid composition in the diet that can affect feed intake of T. haematodus. Therefore, this information will help to make a formulation of appropriate diet that meets the nutrient requirements especially amino acid for the birds.

Abstract

Providing scientific evidences for the medicinal benefits and possible toxic effects of the flamboyant flowers (Delonix regia (Bojer ex Hook.) Raf.) are very important to implementing the medicinal plant in this modern era. This study aimed to investigate antidiabetic potential of methanol extract of flamboyant flowers using a completely random design. Twenty-four male rats were randomly divided into 6 treatment groups with 4 replications: healthy rats (normal control, P1), diabetic rats treated with flamboyant flower extract of 0 (negative control, P2), 100 (P3), 200 (P4), and 400 mg/kg BW (P5), and rats which were induced by 0.45 mg/kg BW of Glibenclamide (positive control, P6). Diabetic condition was achieved by a single injection of alloxan 150 mg/kg BW. Treatments were given once a day for 14 days. On day 0, 3 and 18 blood samples were withdrawn from rats’ orbital vein for glucose measurement. All rats were sacrificed for liver, gastrocnemius muscles and pancreatic tissues collection. The liver and gastrocnemius muscle were subjected for glycogen measurement whereas pancreatic tissues were processed for histological examinations. Data was analyzed by ANOVA and followed by Duncan test. The results showed that flamboyant flowers extracts significantly (p<0.05) reduced blood glucose as well as degeneration and necrosis of pancreatic β cells. Optimal dose to decrease blood glucose and pancreatic cell degeneration was 200 mg/kg BW; whereas optimum dose to decrease pancreatic cell necrosis was 400 mg/kg BW. In conclusion, flamboyant flower extract can reduce blood glucose in rats. This is the first that shows antidiabetic potential of local Flamboyant flower extracts along its toxicity effect to pancreatic tissues. These information could become a basic consideration for the use of the plant extracts as a candidate to cure patients with diabetic problems.
