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

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).

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

Bacterial communities associated with white shrimp (Litopenaeus vannamei) larvae at early developmental stages. Biodiversitas 11 (2): 65-68.Terminal Restriction Fragment Length Polymorphism (T-RFLP) was used to monitor the dynamics of the bacterial communities associated with early developmental stages of white shrimp (Litopenaeus vannamei) larvae. Samples for analysis were egg, hatching nauplii, 24 hours old nauplii, and 48 hours old nauplii which were collected from one cycle of production at commercial hatchery. TRFLPresults indicated that the bacterial community associated with early stages of shrimp development might be transferred vertically from broodstock via egg. There was no significant difference between bacterial communities investigated, except the bacterial community of 48 hours old nauplii. Diversity analyses showed that the bacterial community of egg had the highest diversity and evenness, meanwhile the bacterial community of 48 hours old nauplii had the lowest diversity. Nine phylotypes were found at all stages with high abundance. Those TRFs were identified as γ- proteobacteria, α-proteobacteria, and bacteroidetes group.Key words: Litopenaeus vannamei, bacterial community, T-RFLP

Abstract

Karyawati AT, Nuraida L, Lestari Y, Meryandini A. 2018. Characterization of abundance and diversity of lactic acid bacteria from Apis dorsata hives and flowers in East Nusa Tenggara, Indonesia. Biodiversitas 19: 899-905. Previous research on lactic acid bacteria associated with honey bees has been conducted in temperate arid regions and wet tropical regions. We isolated lactic acid bacteria from giant honey bee (Apis dorsata) hives and flowers in East Nusa Tenggara, Indonesia, an area with a tropical savanna climate. Diversity of lactic acid bacteria was studied using Denaturing Gradient Gel Electrophoresis method. The purpose of this study was to obtain information about the diversity of lactic acid bacteria contained in Apis dorsata hives and flowers from tropical savanna climate. We identified seven Operational Taxonomy Units (OTU) within the hives and flowers. Two OTUs were closely related to LactoBacillus kunkeei strain YH-15 (T), while three others were closely related to Lactococcus lactis subsp. tructae strain L105 (T). This information is important to explore the potential utilization of lactic acid bacteria in maintaining human health.

Abstract

Janatiningrum I, Solihin DD, Meryandini A, Lestari Y. 2018. Comparative study on the diversity of endophytic actinobacteria communities from Ficus deltoidea using metagenomic and culture-dependent approaches. Biodiversitas 19: 1514-1520. Actinobacteria endophytes of medicinal plants may play an essential role in producing a variety of critical bioactive compounds. However, the possible contribution of such actinobacteria to the pharmacological properties of traditional herbal remedies remains mostly unknown. For example, the diversity and attributes of actinobacteria endophytes in Ficus deltoidea, a small tree species that has long been used to treat diseases such as cancer, diabetes, and cardiovascular illnesses, have not been explored. Here, the actinobacteria endophyte community structure in F. deltoidea was investigated using both culture-dependent and metagenomics approaches. Based on morphological characteristics and 16S rRNA gene analysis, the dominant culturable actinobacteria isolates exhibited a close relationship with Streptomyces. The metagenomic technique using PCR-DGGE analysis of the 16S rRNA gene showed the presence of 11 OTUs in F. deltoidea tissue. Whereas the dominant culturable actinobacteria endophytes in F. deltoidea was Streptomyces, the metagenomic approach showed non-Streptomyces, particularly Rhodococccus and Verrucosispora, to be also important. Thus, results from both culture-dependent and metagenomic approaches provided useful indicators on the diversity and community structure of actinobacteria endophytes in F. deltoidea.

Abstract. Larasati F, Batubara I, Lestari Y. 2020. The presence of endophytic actinobacteria in mangosteen peel (Garcinia mangostana L.) and its antioxidant activity. Biodiversitas 21: 1488-1497. Mangosteen (Garcinia mangostana L.) is a family member of Clusiaceae which is rich in secondary metabolite compounds that can function as antioxidants. Besides being produced by its host plant, the bioactive compounds can also be produced by endophytic actinobacteria. The purpose of this study was to explore the presence of endophytic actinobacteria from mangosteen peel and determine its antioxidant activity. The actinobacteria were isolated, purified, morphologically characterized, molecularly identified, extracted with ethyl acetate and tested for antioxidant properties. The antioxidant activity was assayed using DPPH (2.2-diphenyl-1-picrylhydrazyl) and ABTS (2,2?-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) methods. The components of extracts were separated by Thin Layer Chromatography (TLC) and bioautography was done to determine the antioxidant bands. As a result, five isolates of endophytic actinobacteria in mangosteen peel showed to have difference in aerial mycelium color, substrate mycelium color, and types of spore chains. Based on 16S rRNA gene analysis, AGM3.2 isolate showed similarity with Streptomyces griseochromogenes ATCC 14511 (T) 99.06%. AGM3.1 had similarity with Streptomyces osmaniensis OU-63 (T) 98.35%. Meanwhile, AGM2.3 were similar to Streptomyces xanthophaeus NBRC B-5414 (T) 99.82%, AGM2.2 had similarity with Streptomyces xanthophaeus NBRC B-5414 (T) 98.95%. In addition, AGM2.1 has homology with Streptomyces goshikiensis NBRC 12868 (T) 99.52%. Using both DPPH and ABTS, supernatant of AGM2.1 showed the highest antioxidant activity indicated by 36.96 and 98.80 inhibition, respectively. Antioxidant capacity of ethyl acetate extract of AGM2.1 was 22.22 ?g AEAC/mg extract (DPPH) and 20.34 ?g AEAC/mg extract (ABTS). Meanwhile, ethyl acetate extract of mangosteen peel had antioxidant capacity by 21.17 µg AEAC/mg extract (DPPH) and 18.75 µg AEAC/mg extract (ABTS). Antioxidant bioautographic analysis of mangosteen peel ethyl acetate extract was compared with alpha mangosteen standard. The results showed that alpha mangosteen presence in the mangosteen extract with the same Rf value of 0.64 with standard. Meanwhile, actinobacterial ethyl acetate extract from AGM3.1, AGM2.3, AGM2.2, AGM2.1 each have the same Rf value with the alpha mangosteen standard. However, the spot for alpha mangosteen had dark red color, while spots of the four actinobacterial isolates showed to have blue color indicating different antioxidant compounds. The blue spot indicates the flavone, flavanone, flavonol, and isoflavone. These compounds include a subgroup of flavonoid compounds. Ethyl acetate extract AGM3.2 does not have spot compounds with the same Rf value as the alpha mangosteen standard. Study clearly shows that endophytic actinobacteria from mangosteen peel have potency as antioxidant.

Abstract. Retnowati D, Solihin DD, Ghulamahdi M, Lestari. 2021. Next-generation sequencing-based Actinobacteria community associated with Callyspongia sp. from Kepulauan Seribu Marine National Park, Jakarta, Indonesia. Biodiversitas 22: 3702-3708. Sponges are sessile benthic filter-feeding animals, which harbor numerous microbes. The enormous community and abundance of sponge-associated actinobacteria envisage sponges as hot spots of microbes. The metagenomic approach with Next Generation Sequencing (NGS) technology was used to investigate the actinobacteria community of Callyspongia sp. collected from Kepulauan Seribu Marine National Park, Indonesia. Fourteen actinobacteria families were found associated with the sponge. Among them, Microbacteriaceae was the most dominant family. The community of actinobacteria was higher than that of the culturable method from our previous study. The research showed that a metagenomic approach using NGS technology reveals better information regarding the actinobacteria community associated with Callyspongia sp.
