Abstract

Xylocarpus granatum produces various bioactive compounds with diverse biological activities, one of them as an antioxidant. Endophytic actinobacteria can also produce bioactive compounds. This study aimed to explore the existence of the endophytic actinobacteria of X. Granatum and determine its antioxidant activity. The research method begins with the isolation of endophytic actinobacteria from fruits, seeds, and leaves using selective media Humic Acid (HV). Furthermore, characterizing the obtained isolates using four different media, namely YSA, ISP2, ISP3, and ISP4, measured antioxidant activity for actinobacterial supernatants and actinobacterial ethyl acetate extracts using the DPPH method. The results showed that from X. granatum, 15 isolates of endophytic actinobacteria were obtained from fruit, seeds, and leaf. Endophytic actinobacteria isolates from X. granatum showed different colors of aerial mycelium, substrate mycelium, and spore chain type. XGF11, XGF12, and XGF4 isolates produced high antioxidant activity of the supernatant; 57.30%, 49.77%, and 41.90% inhibition, respectively. The antioxidant capacity of XGF12 ethyl acetate extract was 501.60 μg AEAC/mg extract and 465.47 μg AEAC/mg extract for XGF11 ethyl acetate extract. DNA extraction and 16S rRNA amplification from endophytic actinobacteria X. granatum according to Presto Mini gDNA Bacteria Kit Protocol. Based on 16S rDNA gene analysis, isolates XGF12 and XGF11 showed 99.16% and 99.42% similarities with Streptomyces xylanilyticus, respectively. Meanwhile, XGF4 showed to have 99.82% similarities with Brevibacterium sediminis.

Abstract

Tidal areas are believed as future land for many commodities in Indonesia. Here, shallot growing was evaluated on tidal land supplemented with soil conditioners. The research aimed to evaluate the adaptive response of shallot varieties for growing on tidal land with a water-saturated system indicating Fe and Al stress by applying soil ameliorant and actinobacterial. The study used a completely randomized factorial design with three replications. The first factor was shallot variety (Bima Brebes, Batu Ijo, and SS Sakato) and the second factor was soil conditioners (no ameliorant, actinobacteria, ameliorant+actinobacteria, and actinobacteria+ameliorant+dolomite). Bima Brebes and Batu Ijo cultivars had the highest growth percentage, age at shoot emergence, plant height, and number of leaves, while the SS Sakato variety had the slowest growth. Shallot production variable had a significant interaction with soil conditioners. Bima Brebes variety demonstrated high suitability for a water-saturated system in tidal land, and actinobacteria+ameliorant+dolomite was a more promising conditioner than other treatments. Keywords: pyrite, saturated soil culture, tidal swamps, growth, yield, marginal land.

Abstract

Honey is a healthy, natural product with high nutritional value that is converted from sugar in nectar by bacteria in the honey stomach of the bees. Several beneficial bacteria in honey produce bioactive compounds, such as Lactobacillus in Apis mellifera honey, which synthesizes lactic acid, bacteriocins, and enzymes. Here, we employed the metabarcoding technique using the 16S rRNA gene to identify the bacterial community in honey from A. cerana and Heterotrigona itama collected in Sukabumi Regency, West Java, Indonesia. Genomic DNA from both honey samples was isolated using the ZymoBIOMICSTM DNA miniprep kit before sequencing with the Oxford Nanopore Technologies (ONT) platform. Our studies showed that the most dominant bacteria in the honey of A. cerana and H. itama were Paenibacillus glucanolyticus and Limosilactobacillus, respectively. In both types of honey, Gram-positive and Gram-negative bacteria were also detected, as well as lactic acid bacteria, including Acetilactobacillus jinshanensis and Limosilactobacillus. We also found Actinobacteria in A. cerana and H. itama honey. This genomic data showed that A. cerana honey has a higher bacterial diversity than H. itama. Our finding is the first genomic study of bacterial diversity found in the honey of A. cerana and H. itama that live sympatrically in a bee farm.

Abstract

A total of 137 strains of Actinomycetes were isolated from 14 soil samples collected in 3 part of Lombok Island, Indonesia using SDS-YE (SY) and Rehydration and Centrifugation (RC) isolation methods and Humic Acid Vitamin (HV) agar as isolation media. All the isolates were identified by morphological characteristic and by analysis of 16S rRNA gene sequence. On the basis of their morphology and 16S rRNA gene sequence, 67% of isolates were belonged to the Streptomyces Group and 33% of isolates were belonged to the Rare-Actinomycetes (Non-Streptomyces) Group. Nine families and 15 genera were found from the samples. It is indicated the richness of actinomycetes in these area. The genus Streptomyces is the most abundant in all soil samples, occupying 67% of all isolates by using SY method; while the genus Actinoplanes is mainly found by using RC as isolation method. Two strains belong to the genus Virgisporangium and Catenulispora that showed taxonomic interest need further study for describing as ne species.

Abstract

A total of 29 actinomycetes strains were isolated and identified by full sequence analysis of the 16S rRNA gene. Samples were collected from Bali Island, Indonesia, including 18 soil and 20 leaf litter samples from Eka Karya Botanical Garden. Two isolation methods were used in this study: SDS-extract (SY) and Rehydration-Centrifugation (RC). Based on 16S rRNA gene analysis, the isolated actinomycetes were grouped into two genera. Molecular analysis of 16S rRNA gene similarities showed that the actinomycetes isolated from Eka Karya Botanical Garden were of diverse origin. Analysis of soil samples resulted in 144 isolates belonging to 24 genera and more than 87 species, with Streptomyces being the dominant genus. This was followed by Actinoplanes (25 isolates, 17%). From leaf litter samples, 85 isolates were obtained, belonging to 9 genera and more than 41 species. The most dominant genus was Catenuloplanes (42 isolates, 49%), followed by Actinoplanes (16 isolates, 19%).

Abstract

Low birth weight (LBW, <2,500 g) remains a critical public health problem, contributing to neonatal mortality and long-term risk of non-communicable diseases, and national estimates in Indonesia indicate a prevalence ranging from approximately 6.2% to 11.7%. Parity and interpregnancy interval (IPI) are important reproductive determinants of perinatal outcomes, and their effects may be modified by socioeconomic status (SES). This study aimed to investigate the association between parity and IPI with LBW and to assess whether SES modifies these associations in a prospective cohort of pregnant women in Yogyakarta, Indonesia. A total of 120 women (poor households n=48; non-poor households n=72) were recruited purposively from community health centers and a maternity hospital/clinic. Inclusion criteria were gestational age 26–35 weeks, maternal age 20–35 years, parity 1–2, non-smoker, and provision of informed consent. Pre-pregnancy BMI was obtained through maternal recall of the last measured height and weight before conception. Data were analyzed using Pearson’s χ² tests for baseline comparisons and stratified logistic regression models to estimate adjusted odds ratios (aORs) with 95% confidence intervals. The prevalence of LBW was higher among women with non-optimal IPI (<24 or >60 months and primigravida) compared to those with optimal IPI (24–60 months). Multiparity showed a protective tendency against LBW, particularly among non-poor women. SES significantly modified the association between IPI and LBW (p for interaction <0.05). These findings suggest that multiparity may reduce LBW risk, whereas non-optimal IPI increases it, with SES acting as an effect modifier. Strengthening preconception counseling on birth spacing and targeted support for low-SES families are warranted

Abstract

Diabetes is a disease caused by insulin dysfunction or impaired insulin production, leading to elevated blood glucose levels (hyperglycemia). It is classified into three types: Type 1, Type 2, and Gestational Diabetes Mellitus (GDM). Type 2 diabetes is a condition resulting from insulin resistance. Previous research has identified microorganisms isolated from Ficus deltoidea that produce α-glucosidase inhibitors. This study aims to determine the potential of extracts derived from Streptomyces tendae as an α-glucosidase inhibitor through both in-vitro and in-vivo assessments, specifically evaluating the extract's effectiveness in reducing blood glucose levels in Sprague Dawley rats with Type 2 diabetes. Although the isolates from previous studies showed a decrease in activity, they remained capable of lowering blood glucose levels in the rats. Statistical analysis of the Oral Glucose Tolerance Test (OGTT) provided sufficient evidence to conclude that the combination of time (minutes) and extract administration significantly influenced the reduction of blood glucose levels in diabetic rats (P<0.05). Diabetes was induced in the rats using low-dose streptozotocin. The results showed that "Dose 1" of the extract significantly reduced blood glucose levels compared to control (aquades) treatment starting from the fifth day of administration and was effective in suppressing further increases in blood sugar (P<0.05).
