Abstract

Sea level is a key oceanographic variable that exhibits both spatial and temporal variability and serves as an important indicator of global and regional ocean–climate variability, which can influence fishery productivity. Using satellite observation data, this study aimed to identify patterns and fluctuations in sea level trends and variability, and to examine their effects on the catch rates of Eastern Little Tuna (Euthynnus affinis) in the Makassar Strait over a ten-year period (2013–2022). Sea level time series were generated through averaging calculations and spatial mean mapping to characterize sea level distribution. Histogram analysis was applied to determine the frequency of catch per unit effort (CPUE) across different sea level ranges. The results showed that mean sea level in the Makassar Strait during the study period ranged from 0.48 to 0.78 m. Clear annual and seasonal sea level variability was observed, with higher values (0.65–0.70 m) during the northwest monsoon and lower values (0.50–0.60 m) during the southeast monsoon. Over the ten-year period, sea level increased by approximately 0.13 m. The highest CPUE of Eastern Little Tuna was associated with sea levels between 0.60 and 0.65 m. Histogram analysis further indicated that this sea level range corresponded to the maximum CPUE values. In contrast, higher sea levels ranging from 0.75 to 0.80 m were associated with the lowest CPUE, value of 30 kg/trip.

Abstract

The availability of a healthy stock of seedlings is fundamental for raising plantations. A survey was conducted from 2023 to 2024 to observe the occurrence of diseases in forest nursery seedlings in different zones of the Oromia and Amhara regions. During the survey, various plant species were examined for disease occurrence. It was found that E. camaldulensis, E. globulus, Acacia decurrens, Cupressus lusitanica, Grevillea robusta, A.indica, Juniperus procera, Pinus patula, and Dovyalis abyssinica were infected by a disease. The assessment recorded seven seedling diseases, with 12 fungal genera of pathogens isolated. The recorded symptoms of disease during the study included powdery mildew, damping-off, leaf spot, leaf blotch, rust, shoot dieback, and wilting. The pathogens identified from the recorded diseases symptoms were B.cinerea, Alternaria ,Pestalotiopsis spp., Podosphaera spp., Fusarium spp., R.solani, Cylindrocladium spp.,Uromycladium spp.,Phoma spp.and Pythium spp. Rhizoctonia solani was frequently isolated from the damping-off symptoms. Field observations indicated that damping-off on C.lusitanica  and p.patula, as well as powdery mildew on Eucalyptus species, are becoming serious problems that limit the production of nursery seedlings. The infection of disease is greatly influenced by improper nursery practices during seedling production, location and type. Some the recorded diseases can cause losses in seedling quality and quantity which can affect plantation programs. The surveys reported here provide a foundation for understanding the status of forest nursery diseases in Ethiopia and serve as a useful reference for assessing current and future forest disease developments and management. Further study on inoculum sources and the morphological characteristics of pathogens associated with seedling diseases using molecular tools is also needed.

Abstract

Bacteriophages, or phages, are viruses that can infect and replicate within bacterial cells, such as Escherichia coli. Phages demonstrate a strong ability to lyse host bacteria and exhibit high survivability, making them a promising innovation for use in non-alcoholic antiseptic products, such as hand sanitizer sprays and bacteriophage gels. This study aims to evaluate the effectiveness of bacteriophage-based hand sanitizer sprays and gels in reducing E. coli growth and total microbial colonies on palms, compared to commercial alcohol-based hand sanitizers. The method used in this study is a descriptive quantitative approach using an experimental method, specifically the Hand Sanitizer Spray and Bacteriophage Gel Test as Non-Alcohol Antiseptics. The average total bacterial colonies on male palms for the control treatment, phage gel sanitizer and commercial gel hand sanitizer were 1.95 x 104 CFU/mL; 1.15 x 103 CFU/mL; 2.55 x 103 CFU/mL, respectively,  while on female palms, the values were 2.35 x 104 CFU/mL; 3.05 x 103 CFU/mL; 1.65 x 103 CFU/mL. The average total bacterial colonies on male palms for control treatment, phage sanitizer spray and commercial sanitizer spray were 1.30 x 105 CFU/mL; 2.05 x 103 CFU/mL; 9, 04 x 104 CFU/mL, respectively, while on female palms, the value was 1.58 x 105 CFU/mL; 8.36 x 103 CFU/mL; 8.79 x 104 CFU/mL. The results demonstrated that both bacteriophage hand sanitizer gel and spray significantly reduce bacterial colonies on palms, with phage-based hand sanitizer showing greater efficacy than commercial alcohol-based hand sanitizer.

Abstract

The gut microbiota, a community of microorganisms residing in the digestive tract, plays a crucial role in human health, particularly in regulating immune function and metabolism. This study aims to explore the contributions of the gut microbiota to immune responses and metabolic health, as well as its role in preventing chronic diseases. Through a literature review approach, an analysis was carried out regarding the latest findings of the role of microbiota in producing metabolites such as short-chain fatty acids (SCFAs), which act as anti-inflammatory agents and strengthen mucosal integrity. A balanced gut microbiota helps regulate immune function, inhibit pathogen colonization, and support overall metabolic health. However, lifestyle factors such as high-sugar, low-fiber diets, antibiotic misuse, stress, and inadequate sleep can disrupt this microbial balance, often leading to dysbiosis. Dysbiosis, or an imbalance in gut microbiota, may trigger metabolic and inflammatory disorders, including diabetes, autoimmune diseases, and cardiovascular conditions. This study underscores the importance of maintaining a balanced gut microbiota for disease prevention and long-term health promotion, as well as raising awareness about the impact of lifestyle choices on gut health.

Abstract

Drying has the potential to alter the physical, chemical, and organoleptic characteristics of food materials. This study aims to identify the composition of non-volatile flavor compounds in fresh and dried sea lettuce (Ulva lactuca). The identification of non-volatile flavor compounds was conducted using amino acid profiling through High-Performance Liquid Chromatography (HPLC). The organoleptic characteristics, including appearance, aroma, texture, and taste of fresh and dried sea lettuce samples, were assessed through a simple descriptive test. The quantitative amino acid analysis data and the descriptive test results were analyzed using a comparative descriptive method. The findings revealed that both fresh and dried Ulva lactuca contain 17 types of amino acids, comprising 9 essential amino acids and 8 non-essential amino acids, which influence flavor characteristics. The descriptive test indicated that fresh Ulva lactuca is characterized by clean, shiny, and soft light green to dark green sheets with an elastic texture and a distinctive fresh seaweed aroma. In contrast, dried Ulva lactuca exhibited a yellowish-green color, a stiff and brittle texture, and a stronger salty taste with a slight umami sensation. These findings highlight the potential of Ulva lactuca as a versatile ingredient in food product development, particularly for enhancing flavor and nutritional value.

Abstract

Some endophytic bacteria are known to have hydrolytic activity by producing hydrolase enzymes. Endophytic bacteria can be found in plant tissue. Exploration of endophytic cellulolytic bacteria in water apple (Syzygium aqueum) fruit has not been widely carried out, so this research is the first to be conducted. This study aimed to isolate, screen, and identify endophytic bacteria from water apple fruit that could produce cellulase enzymes. The research began with bacterial isolation. Then, cellulolytic screening was carried out by inoculating the isolates into a differential medium containing cellulose, Bushnell-Haas agar (BHA). The screening results were characterized and identified through 16S rDNA gene sequence analysis. The isolation results indicated that seven bacterial isolates were screened for cellulolytic activity by cultivating them on BHA medium. The screening revealed that one isolate encode CSZA2 had cellulolytic activity with a cellulolytic index of 0.87. Biochemical characterization and molecular identification of the CSZA2 isolate showed a 99.93% similarity to the Pseudomonas putida RTI2, a bacterium known for producing cellulase enzymes. The discovery of bacterial cellulolytic activity can be developed for biomass degradation, bioethanol production, and agricultural biotechnology.

Abstract

Mucor irregularis JR 1.1 is a filamentous fungus that can produce lipids. The lipids produced by M. irregularis JR 1.1 reach 40-60%, so they can be used as raw material for biodiesel. Temperature and pH are important factors that support M. irregularis JR 1.1 lipid production. Optimum temperature and pH enhance the activity of enzymes involved in lipid production.  Based on previous research, the optimization of temperature and pH in the lipid production of M. irregularis JR 1.1 has not been determined. Therefore, this study aims to determine the optimal temperature and pH for lipid production by M. irregularis JR 1.1. The study involved varying temperature and pH treatments using Response Surface Methodology (RSM). Subsequently, lipid production was performed at the optimum temperature and pH under different incubation times. Based on the research results, the highest biomass production was observed at 35°C and pH 4, the highest lipid production was at 35°C and pH 5.5, and the highest glucose consumption rate was at a temperature of 23°C and pH 5.5. The highest lipid yield percentage was 6.2%, and the highest production rate was 0.011g/L/hour at the 96th hour of incubation. Statistical analysis showed high significance, with R² values of 95.88% for lipid production and 89.98% for biomass yield. These findings suggest that M. irregularis JR 1.1 has promising potential as a microbial lipid source for sustainable biodiesel production, particularly under optimized culture conditions.

Abstract

Maize and silage play a critical role in livestock nutrition, offering a cost-effective feed with a balanced nutrient profile. Improving maize and silage quality is essential for maximizing animal performance. This study aimed to evaluate the nutritional composition, fiber content, pH levels, and bacterial activity in silage made from two maize varieties—KMHB410 and HMS-PS-3355—using varying levels of molasses as an additive to improve silage quality. The study was conducted in Sylhet, Bangladesh where an absence of green grass causes the cattle to suffer from malnutrition throughout the lean season. Here silage was produced by mixing the chopped maize with 5% and 10% molasses, along with a control group. After 15 days of fermentation, the silage was assessed for dry matter (DM), ether extract (EE), crude protein (CP), crude fiber (CF), and acid detergent fiber (ADF), and the presence of Lactobacillus spp.  The study of Dry matter (DM) content ranged from (8.54 to 17.25) %, with HMS-PS-3355 at 17.25% and KMHB 10% molasses at 8.54% (P=0.002). Crude protein (CP) varied significantly (P=0.002), with KMHB C showing the highest value at 19.04%, while HMSC recorded 10.36%. The addition of molasses significantly reduced acid detergent fiber (ADF) content. Bacterial colony-forming units (CFU) were highest in the control silage (97×10⁶ CFU), while the 10% molasses treatment had the lowest count (38×10⁶ CFU), indicating that increased molasses concentrations reduced microbial growth. Confirmation and screening of Lactobacillus spp. in silage was carried out by culturing the microorganisms in a lactobacillus selective MRS media followed by different biochemical tests.

Abstract

Treatment with natural ingredients is essential for healing incision wounds. One promising natural remedy is land snail mucus, which has been used for centuries to address various health conditions, including wounds. This study aimed to evaluate the effects of mucus from Amphidromus palaceus and Lissachatina fulica on collagen density during the healing process of incision wounds in Rattus norvegicus. The in vivo study included 36 rats, divided into four cages with nine rats per cage. Each of rats subjected to approximately 1 cm incision wounds on their backs. The rats were divided into four groups: a negative control group (KN) receiving aquades, a positive control group (KP) treated with 1% bioplacenton, treatment group 1 (P1) receiving 25 µL of A. palaceus mucus, and treatment group 2 (P2) receiving 25 µL of L. fulica mucus. The experiment concluded on days H3, H5, H7, and H10. Histological preparations were made using MT staining to assess collagen density. The results showed both species of snail mucus significantly increased collagen density compared to the negative control (aquades). However, there were no statistically significant differences when comparing L. fulica, A. palaceus, and bioplacenton. Among all the treatment groups, L. fulica mucus (P2) produced the highest collagen density. These findings suggest that both types of snail mucus hold promising potential in promoting the wound healing process.
