ABSTRACTThis study aimed to evaluate the production performance and physiological of Nile tilapia using Lemna perpusilla as a phytoremediator in a recirculation system. A completely randomized design with two treatments and three replications was applied. The treatments were Nile tilapia cultured with L. perpusilla (TL) and without L. perpusilla (L). The experimental fish in this study was the juvenile of Nile tilapia with a body length of 9.98 ± 0.08 cm and an average weight of 36.27 ± 1.07 g. The stocking density was 46 fish/pond and the container size was 275×100×60 cm3 and was separated in two areas using a fiber separator screen of 55.9% area for fish culture and 44.1% for L. perpusilla. The Nile tilapias were reared for 60 days, fed with commercial diet and fresh L. Perpusilla with amount 2% and 1% of biomass, respectively. They were fed three times a day with fresh L. perpusilla at noon and commercial diet in the morning and afternoon. The results showed that the Nile tilapia reared with L. perpusilla phytoremediation had normal physiological condition and production performance. The predominances of this system were lower feed conversion ratio value, more optimal values of feeding efficiency, and higher coefficient of weight uniformity. Keywords: Lemna perpusilla, physiological condition, phytoremediation, production performance.

As a social insect, termite colony consists of three castes, i.e. reproductive, soldier, and worker castes. In their role of cellulose digestion, the worker termites use two sources of cellulolytic enzyme that include cellulases produced by the termite and the gut symbions. Macrotermes gilvus classified in mound builder termite, mostly depend on cellulolytic bacteria for cellulose digestion. This study aims to characterize cellulolytic bacteria of termite gut symbionts of worker M. gilvus and to identify the cellulolytic bacteria based on sequences of 16S ribosomal RNA (rRNA) gene. Cellulolytic bacteria of termite gut were isolated and cultured in CMC (Carboxymethyl cellulose) media. The biochemical characters of bacterial isolates were assayed using Microbact 12A and 12B. Cellulolytic activity was determined based on formation of clear zone and cellulolytic index on CMC plate media. The bacterial isolate that has the highest cellulolytic index was analyzed for its 16S rRNA gene sequences. Four isolates of cellulolytic bacteria were successfully isolated from gut of M. gilvus with aerobic and anaerobic conditions. The highest formation of cellulolytic index (2.5) was revealed by RA2. BLAST-N (Basic Local Alignment Search Tool for Nucleotides) result of 16S rRNA gene sequences of RU4 and RA2 isolates showed that the isolate has similarity with Bacillus megaterium and Paracoccus yeei, respectively. This result indicated that RA2 isolate was P. yeei, a cellulolytic bacterium of a termite gut of M. gilvus.

Former kaolin mining has poor physical and chemical properties for plants. The low nutrient content makes difficult for plants to grow. Nitrogen (N2) is an important macronutrient for plants, but it can only be absorbed in the form of ammonium ions (NH4+) or nitrate ions (NO3-). Therefore, it is necessary to transform nitrogen, which is able to change the molecular form so that it can be absorbed by plants. The strategy that can be done is using nitrogen-fixing bacteria. This study aimed to explore and analyze the diversity of nitrogen-fixing bacteria based on 16S rRNA and nifH gene from the rhizosphere of the Kaolin Lake area. The method started with bacterial isolation from rhizosphere soil samples. Selected isolates were tested for ammonium content to determine the ability of isolates to fix nitrogen. In this study, 13 isolates had the ability to fix nitrogen, two of which had a high ammonium concentration, namely RBN 5.6, and RBA 2.3. The highest ammonium concentration was produced by isolate RBN5.6 amounting to 7.55 μg/ml. Based on 16S rRNA gene identification, isolate RBN5.6 was similar to Burkholderia cepacia and isolate RBA2.3 was similar to Bacillus aquimaris. Based on the detection of the nifH gene, isolate RBN5.6 was identified as a protein-encoding dinitrogenase reductase gene group cluster from the Stutzerimonas stutzeri.

Chitinolytic bacteria have been reported as biocontrol agents and have the ability to produce chitinase enzymes. The objective of the research was to obtain chitinase producing bacteria that had antagonistic activity to Ganoderma boninense, a causal agent of basal stem rot on oil palm. A total of 63 isolates of chitinase producing bacteria were isolated from soil of Bukit Dua Belas National Park and oil palm plantation in Jambi Province; all was screened for their potency in inhibiting G. boninense in vitro. Three isolates designated TB04-05, SW01-11, and SW02-08 were potentially suppressed and inhibited the mycelium growth of G. boninense in vitro. Based on their specific chitinase activity, these three isolates produced the highest level of chitinase enzyme of 6.3072 U mg-1 protein, 6.0385 U mg-1 protein and 6.1279 U mg-1 protein, respectively after 24 hr incubation. Based on 16S RNA identification, strain TB04-05 had similarity with Bacillus cereus, whereas strains SW01 and SW02-08 had similarity with Bacillus thuringiensis.

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.

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.

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.

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.

Kaur Regency is a high-potential vannamei shrimp (Litopenaeus vannamei) aquaculture area in Bengkulu Province that frequently experiences high mortality rates due to vibriosis caused by pathogenic Vibrio spp. The high shrimp mortality rates resulting in decreased production or crop failure due to attacks or infections of vibriosis disease. Data on these Vibrio spp. in traditional Kaur ponds is required for illness prevention. To identify pathogenic Vibrio spp., this study included purposeful sampling and testing, as well as data analysis. Seven Gram-negative isolates (OALF 1, 2, 3, and 5 from shrimp organs; WALF 7, 8, and 10 from pond water) produced green/yellow colonies on TCBSA medium. Biochemical tests (Gram KOH 3%, catalase, oxidase, fermentation (O/F), TSIA, MIO, lysine decarboxylase, gelatin, Simon citrate, methyl red, urease, glucose, maltose, lactose, mannitol, and sorbitol) revealed that OALF isolates from vannamei shrimp organs have morphological and physiological similarities to the pathogenic species Vibrio parahaemolyticus, whereas WALF isolates from pond water are similar to the pathogenic species V. pluvialis. The study identified Vibrio spp. as the cause of vibriosis in L. vannamei in traditional Kaur ponds, emphasizing the need for improved water and feed management, as well as proper pond environmental practices, potentially including probiotics derived from healthy local shrimp digestive bacteria, to reduce losses in vaname aquaculture in Kaur Regency, Bengkulu. Keywords: Litopenaeus vannamei, pathogen, traditional ponds, Vibrio, vibriosis
