Abstract

Electrogenic microbes have been exploited in the microbial fuel cell (MFC) system for harvesting bioelectricity. Electrogens are widely distributed in various environments, but the exploration of this microbial group from ecosystems in Indonesia is still limited. This present study aimed to isolate the electrogenic bacteria from sediments of two waterlogged ecosystems (dam and paddy field) using serial dilution into extinction method prior to streak plate method on the solid thioglycollate media supplemented with Fe3+. Electrochemical evaluation was conducted in glucose-fed dual-chamber MFC by using Arduino UNO-based data logger for the accurate monitoring of electricity production in the term of open circuit voltage (OCV). A total of 54 electrogens were successfully isolated from these two ecosystems, ranging from weakness to strongest electrogens (OCV >800 mV) and ranging from microaerophilic, aerotolerant and facultative anaerobes, to obligate anaerobes. This result also suggested that sediment of waterlogged ecosystems rich in electron donor and solid acceptor electron compounds could potentially host electrogenic microbes. The exploration of electrogens from many other waterlogged ecosystems in Indonesia, both natural and anthropic ecosystems, could be conducted to collect genetic resources of novel electrogenic bacteria for the development of MFC technology in Indonesia.

Abstract

AHPND causes up to 80% of shrimp mortality, severely impacting Indonesia's aquaculture. Rising antibiotic resistance necessitates sustainable alternatives. This study investigates the probiotic potential of Pseudomonas alcaligenes SG03, a bacterium with unique genomic traits, to address antibiotic resistance and promote animal health. Genome analysis revealed a 6.17 Mb genome with 4,446 protein clusters, including genes for carbohydrate metabolism (26.63%), amino acid metabolism (19.93%), and energy metabolism (10.88%). Key probiotic-related genes, such as acid resistance (rpoS, actP), salinity tolerance (gshA, cysK), antibiotic resistance (vanB, gyrA), and metal resistance (copZ, zwf), were identified. In vitro, assays evaluated probiotic properties under conditions mimicking the shrimp gastrointestinal tract. Osmo-tolerance tests showed optimal growth at 10% glucose, with a significant drop in viability at higher concentrations. Autoaggregation increased progressively, reaching 0.78 at 18 hours and 0.13 at 48 hours. Optimal growth occurred at 30°C, with a 2.5-fold increase in optical density compared to 25°C. NaCl tolerance peaked at 2% (20.33×1012 CFU at 48 hours), while bile salt tolerance was highest at 0.1% (27.00×1012 CFU at 48 hours). pH tolerance was optimal at pH 5 (20.00×1012 CFU at 48 hours). Antioxidant (53.00%) and anti-inflammatory (60.33%) activities peaked after 48 hours. Phenotypic antibiotic resistance was observed against Tetracycline, Amoxicillin, Cefixime, Streptomycin, and Chloramphenicol, with proteolytic activity but no lipolytic or hemolytic properties. These findings highlight P. alcaligenes SG03’s potential as a probiotic in aquaculture to support shrimp health and reduce antibiotic dependency. Future studies should focus on in vivo validation and formulation development.

Abstract

Bees are one of the pollinators that a honey producing agent as well. Honey derives from nectar that stored and procees in honey stomach. The quality of honey is determined by physical, chemical and microbes in the honey stomach as well. This study was aimed to analyze the diversity of bacterial communities (bacterial metagenome) derived from bee’s honey stomach of A. mellifera, A. cerana, and T. laeviceps using Denaturing Gradient Gel Electrophoresis (DGGE) method. Previous researches of bacterial communities are more focused on the entire digestive tract, which is not specifically in honey stomach of the bees. The diversity of bacterial communities showed differences among three bee’s species. The number one of A. cerana has the highest number of Operational Taxonomic Units (OTUs), i.e., 15 OTUs compared to the other sample. While the T. laeviceps number two show the highest percentage of OTU dominant at 59.4%. The bacterial community in bees honey stomach of A. mellifera, A. cerana, T. laeviceps the similarity of bacteria from phylum Firmicutes, Proteobacteria, Acidobacteria and Fusobacteria. Actinobacteria and Bacteroidetes phyla are found only in A. cerana honey stomach.

Abstract

Household organic waste generated daily holds potential for conversion into bioenergy through biodrying technology. Biodrying is a biological drying process that relies on microbial activity to reduce the moisture content in organic waste, producing solid fuel. This study aimed to formulate a microbial consortium for biodrying applications and to compare the effectiveness of solid (talc-based) and liquid (molasses-based) carriers on biodrying performance and inoculant stability. The consortium comprised Lysinibacillus halotolerans, Bacillus soronensis, Lactobacillus rhamnosus, Pichia manshurica, and phosphate-solubilizing bacteria. Isolate rejuvenation was performed using selective culturing followed by characterization. Microbial formulations were developed in both solid and liquid forms and applied to organic waste. Key parameters observed included moisture content, temperature, pH, and inoculant viability over a three-month storage period. The results showed that both talc and molasses carriers were more effective than commercial controls, as indicated by higher temperatures (44.1°C and 43.66°C), lower moisture content (44.5% and 45.25%), and favorable pH values (5.8 and 6.35), which supported mesophilic and thermophilic microbial activity during the biodrying process. Peak microbial activity occurred on day four, predominantly driven by Bacillus species during the thermophilic phase. Inoculant stability was also higher in the talc-based formulation, potentially due to its magnesium and silicon content, which contributed to maintaining microbial viability during storage.

Abstract

Ketersediaan shelter (tempat perlindungan) pada kepadatan spesifik diharapkan dapat meningkatkan produksi kepiting bakau (Scylla serrata) dalam sistem resirkulasi. Shelter sebagai salah satu faktor abiotik berperan penting dalam mengurangi kematian yang disebabkan oleh kanibalisme kepiting dan menekan tingkat stres biota. Sistem Resirkulasi Akuakultur (RAS) dengan bak kotak kultur berkapasitas 60 L yang didukung oleh shelter diperkirakan menghasilkan respons fisiologis dan pertumbuhan kepiting bakau yang paling baik. Penelitian ini bertujuan untuk mengevaluasi dampak penambahan shelter pada lingkungan dengan sistem resirkulasi terhadap respons fisiologis dan produksi kepiting bakau S. serrata dengan kepadatan 10 kepiting per satu bak kultur yang berisi 60 L air laut. Penelitian ini dilakukan dengan tiga perlakuan penambahan shelter, yaitu 2 shelter (S2), 4 shelter (S4), 6 shelter (S6), dan kontrol tanpa shelter (C). S6 adalah perlakuan terbaik dengan tingkat kelangsungan hidup 73,33±5,8%, laju pertumbuhan spesifik 0,886±0,014%, pertumbuhan lebar karapas 0,024±0,004 cm/hari, dan rasio konversi pakan terendah dibandingkan dengan perlakuan lain. Perlakuan S6 secara signifikan mempengaruhi jumlah hemosit total kepiting pada awal budidaya (P <0,05). Penambahan 6 shelter dapat mengoptimalkan pertumbuhan kepiting lumpur dengan kepadatan 10 kepiting dalam satu bak kotak kultur.

Abstract

Metanotrophic bacteria have ability to oxidize methane and fix atmospheric nitrogen, hence the bacteria has an important role as a nitrogen source provider on wetland area like rice fields. Nitrogen fixation process is catalyzed by the nitrogenase enzyme complex, encoded by nifD and nifH genes. However, characteristic of these genes from indigenous-methanotrophic bacteria still poorly understood. Hence, nifD and nifH genes of methanotrophic bacteria isolated from rice fields in Indonesia (BGM3, BGM9, SS1, SS3, SS10, ST18, SP3, and INP4) were identified and characterized. Detection of nifH and nifD genes was conducted by polymerase chain reaction (PCR) amplification. nifH and nifD gene sequences were analyzed using BLAST-X and phylogenetic trees were constructed using Neighbour Joining method. Based on nifH sequences analysis, SS1 closely related to Beijerinckia mobilis and SS3, SS10, ST 18 closely related to Beijerinckia indica subsp. indica ATCC 9039, while, BGM3, INP4, and BGM9 related to nifH of uncultured nitrogen-fixing bacterium. In other hand, sequence analysis of nifD gene showed that SS1, SS3, SS10, ST 18 closely related to B. indica subsp. indicaATCC 9039 and BGM3, BGM9, INP4 closely related to Xanthobacter autotrophicus Py2. Identification by 16S rRNA gene indicated that SS1, SS3, SS10, and ST18 had closeness to Beijerinckia sp. P310-1, while INP4 closely related to Xanthobacter sp. M5C24.

Abstract

Diabetic ulcers are prone to colonization by multidrug-resistant bacteria, complicating treatment and recovery. Therefore, understanding the microbial profile and resistance mechanisms is essential for effective clinical management. This study isolated and characterized bacteria from diabetic ulcer patients in West Java, Indonesia. Identification was performed using the selective differential medium test and 16S rRNA sequencing. Antibiotic susceptibility was assessed via the disc diffusion method, and biofilm formation was evaluated using crystal violet staining. PCR amplification targeted blaTEM and sul1 resistance genes. A total of 15 bacterial isolates were identified, predominantly Staphylococcus aureus and Pseudomonas aeruginosa. Six isolates exhibited a multiple antibiotic resistance (MAR) index >0.4 and demonstrated biofilm-forming capacity. The PCR result confirmed the presence of blaTEM and sul1 genes in three isolates. The findings highlight the prevalence of multidrug-resistant, biofilm-forming bacteria in diabetic ulcers, underscoring the need for targeted antimicrobial strategies and resistance monitoring.
