Abstract

Phycocyanin is a blue pigment–protein with antioxidant properties, but its use in foods is limited by poor stability. A cyanobacterium, Leptolyngbya sp. CCAH036/1, was isolated from the Can Gio Mangrove Biosphere Reserve, Vietnam, and identified by morphology and 16S rRNA sequencing (96.5% similarity to the closest reference). C-phycocyanin was extracted by freeze–thaw and lysozyme treatment and then encapsulated with maltodextrin using spray drying. The optimized powder contained 20.53 mg/g phycocyanin, 5.14% moisture, 79.43% encapsulation efficiency, and 56.66% antioxidant retention. After three weeks of storage at 4 °C, both pigment content and antioxidant activity remained above 80%. Heating at 50–70 °C preserved about half of the activity, but stronger heat caused rapid decline. Stability was also greatest at pH 5–7. The powder was added to sticky rice mooncakes at 5–20%. At 15% supplementation, the cakes contained 1.874 mg/g phycocyanin and 43.78% antioxidant activity, with no loss of texture or sensory quality. The results indicate that spray drying with maltodextrin is recommended as an effective approach to stabilize phycocyanin from the local Leptolyngbya strain for incorporation into functional foods processed at moderate temperatures and near-neutral pH.

Abstract

Semen quality is one of important factor that impacts cattle reproduction. However, the seminal plasma and spermatozoa separation is still unclear. We attempted proteomic and metabolomic techniques on fresh bovine semen and its compartments to molecularly characterise and cross these two compartments. The proteomic profile of the semen plasma showed pronounced accessory proteins enhancing lipid binding, ion homeostasis, and membrane dynamics, particularly PDC-109, enolases, VDAC2, and SP-10, while the spermatozoa comprised scaffolding, anchoring, and mitochondrial enzymatic proteins such as AKAP3, tektins, cylicins, and COX5B. The dichotomy was reinforced by complementary metabolomic analysis, with seminal plasma containing antioxidants and lipids such as taurine, ergothioneine, palmitoylglycine, and stearamide, while spermatozoa were enriched in metabolites associated with energy, including citrate, inosine, succinic semialdehyde, and pantothenic acid. Pathway analysis reinforced plasma specialisation about antioxidants and lipids rather than spermatozoa on glycolysis and amino acid metabolism with oxidative phosphorylation. Collectively, these results illustrate the presence of interconnected but non-interchangeable molecular domains in which seminal plasma provides protective and regulatory buffering, while spermatozoa are specialised in structural and energetic components for fertilisation. The candidate biomarkers identified from this study such as PDC-109, AKAP3, cylicins, taurine, and citrate illustrate molecular outputs corresponding to the quality of semen and provide a systematised context for enriched understanding of bovine reproductive biology.

Abstract

Phytolacca americana L. (pokeweed) Root contain valuable pharmaceutical compounds but their slow growth and invasive spread make large-scale cultivation difficult. The purpose of this study was to optimize conditions for the enhancement of secondary metabolites while examining the effects of NaCl, MeJA, and SA on the amount of phenolics, flavonoids, and saponins in pokeweed callus cultures. Significant interactions between elicitor concentration and duration were observed for all phytochemical parameters (p < 0.05). MeJA at 100 µM for 3 days and SA at 150 µM for 9 days produced the highest phenolic contents (14.26 and 15.82 µg/mg DW, respectively; p < 0.001) and enhanced antioxidant activities (DPPH, ABTS, FRAP). NaCl at 200 mM for 21 days maximized EsA content (16.73 µg/mg DW), surpassing natural roots and all other treatments (p < 0.001). Phenolic content correlated positively with antioxidant capacity, indicating phenolic compounds as major contributors to antioxidant activity. In contrast, EsA showed negative correlations with other parameters, suggesting its accumulation was independent of phenolic biosynthesis and antioxidant properties. All elicitors upregulated biosynthetic genes via signaling and transcription factor activation. Overall, NaCl, MeJA, and SA effectively enhanced bioactive compounds in pokeweed callus cultures, offering a promising alternative for metabolite production without relying on natural plant resources.

Abstract

This study aimed to evaluate the effects of different selenium (Se) fertilization methods on yield, quality, and organic Se accumulation in pak choi (Brassica rapa L.). A two-year small field experiment (2024–2025) was conducted with four treatments: control (CK), soil application (T1), foliar application (T2), and combined soil plus foliar application (T3). Results indicated that Se treatments significantly increased yield by 4.9–17.55%. Se concentration increased by 175.71–305.71% in root and by 202.81–314.08% in stem. Selenomethionine (SeMet) was the dominant organic form while selenocysteine (SeCys) also increased markedly. Crude protein, ash, and micronutrients (Fe, Zn, and Ca) were enhanced, especially under T3. Overall, the combined soil and foliar application (T3) proved most effective for improving yield, nutritional quality, and organic Se accumulation, offering a sustainable strategy for Se biofortification in leafy vegetables.

Abstract

Herbicides are used worldwide for protection the crops from weeds, but they still pose health problems. We investigated the mechanism of sweet basil (Ocimum basilicum L) methanolic extract (OBLE) against neurotoxicity induced by malathion in rats through the modulation of neurotransmitters, redox changes, cytochrome c release, and apoptosis. This study included sixty male Sprague Dawley rats allocated into six equal groups: Group I, Control; Group II, rats given  malathion  dissolved  in DMSO at the LD50/10 dose (10 µg/kg b.w) orally for 4 weeks; Group III, rats given DMSO orally (0.1 ml/kg b.w) for 4 weeks; Group IV, normal rats treated with OBLE (100 mg/kg) for 4 weeks; Group V (Preventive group), rats administered  malathion   and OBLE orally (100 mg/kg) for 4 weeks; Group VI (treated group), rats administered  malathion   for 4 weeks followed by OBLE for another 4 weeks. The phenolic and flavonoid contents of OBLE were found to be 85 mg GAE /g and 82.65 mg catechin E/g, respectively. Rats given malathion showed a significant reduction in brain acetylcholine esterase (AchE) activity, levels of serotonin, noradrenaline, dopamine and elevation of GABA compared to normal rats. However, rats in the preventive or treated groups with OBLE exert a significant elevation in serotonin, dopamine, and NE levels and activation of AChE activity while GABA level decreased compared with untreated.  Malathion   induced brain tissue Cyt c release, reduced apoptosis markers (caspase 3 and 9) and increased mitochondrial membrane potential (marker of mitochondrial function). OBLE was found to reduce mitochondrial potential, enhance antioxidant activity, reduce the release of Cyt c, and enhanced caspase 3 and 9. The molecular docking analysis showed the potential interactions between the tested compounds target proteins and receptors is reflected by the binding free energies (G) (measured in kcal/mol), with a lower value indicating a more stable interaction. It was concluded that, the phenolic and flavonoid content of OBLE contributed to the neuroprotection against malathion induced neurotoxicity via neurotransmitters, redox status and apoptosis.

Abstract

Endophytic diazotrophic bacteria from non-host crops represent a promising source for developing novel bioinoculants. This study isolated and characterized nitrogen-fixing bacteria from the leaves and twigs of Populus euphratica and assessed their ability to colonize and promote growth in Wheat. From fifty-two isolates obtained on nitrogen-free media, five potent strains—identified by 16S rRNA sequencing as Beijerinckia fluminensis FA-7, Stenotrophomonas maltophilia FA-9, Pseudomonas aeruginosa FA-16, Klebsiella pneumoniae FA-4, and Enterobacter cloacae FA-8 were selected for their nitrogen fixation and plant growth-promoting (PGP) traits. These strains exhibited multiple PGP activities, including phosphate solubilization, indole-3-acetic acid (IAA) production, and the production of siderophores and exopolysaccharides. In growth chamber and wirehouse experiments under varying nitrogen regimes [full (N+), limiting (N-), and zero (N0)], all strains enhanced at least one wheat growth parameter. Notably, Beijerinckia fluminensis FA-7 significantly improved early growth, nutrient uptake, and root architecture—increasing root length, surface area, and fine root development—as confirmed by WinRhizo analysis. Our findings demonstrate that endophytic diazotrophs from Populus can successfully colonize wheat and enhance its growth, highlighting their potential as effective microbial inoculants for agriculture.

Abstract

Reproductive efficiency in livestock can be enhanced through sperm sexing technologies; however, conventional methods such as flow cytometry are expensive, technically demanding, and impractical for field use. Simpler, affordable, and biologically validated alternatives are crucial, especially for indigenous breeds like Bali cattle. This study evaluated the effectiveness of a freeze-dried albumin (egg white) gradient (10%–30%) method for separating X- and Y-bearing spermatozoa in Bali bulls, alongside proteomic profiling to confirm the biological distinctiveness of each fraction. Semen from three mature Bali bulls (Bos javanicus) (n = 3; 5 ejaculates per bull; total 15 ejaculates) underwent separation via the freeze-dried albumin gradient. Sperm quality and kinematic parameters were analyzed using Computer-Assisted Sperm Analysis (CASA), while morphometric assessment estimated sexed sperm proportions. Proteomic analysis using liquid chromatography–tandem mass spectrometry (LC-MS/MS) was followed by gene ontology enrichment, hierarchical clustering, and Pearson correlation, with identified proteins validated against literature. The method enriched X-spermatozoa in the upper layer (69.67%) and Y-spermatozoa in the lower layer (73.50%), with significant differences p < 0.05 in motility, viability, and membrane integrity. Proteomics identified 418 proteins, including 45 unique to X-sperm and 159 unique to Y-sperm. GO enrichment linked X-sperm proteins to nuclear and structural roles, while Y-sperm proteins were associated with mitochondrial and motility processes. Clustering distinctly separated the two sperm types, and several proteins correlated strongly with functional traits. Literature validation confirmed sex-specific markers.  This method represents a low-cost, biologically validated alternative for practical sperm sexing in Bali cattle, combining sperm quality assessment with proteomics to support sex-preferential breeding

Abstract

Insect pests, especially various sucking insects, present significant threat to rice production worldwide including Thailand. This research remarks, for the first time, the occurrence of the white-spotted stink bug (Eysarcoris ventralis Westwood, 1837) in rice fields in northern Thailand. We conducted surveys in 304 rice fields across 12 provinces, collecting data on cultivation practices, water management systems, and rice growth stages, while also recording samples of both nymphs and adult rice pests. The surveys revealed that 26.64% of rice fields were infested by E. ventralis. Morphological analysis confirmed the insect is a member of the genus Eysarcoris, family Pentatomidae. Broadcasting rice fields reported an infestation level at 70.37%, while irrigated rice fields showed a 77.78% of infestation. Ecological factors, such as high moisture, dense plantings, and continuous planting create a favorable condition for the spread of this insect. The susceptible stages of rice are the booting and heading stages. During these stages, both nymphs and adults feed on leaves, stems, and especially developing grains This feeding results in damaged seeds and reduced yields. Six surrounding grass weeds were also found to be alternative host plants for development and off-season survival. Our results emphasize the significance of the white-spotted stink bug, E. ventralis, as a new emerging insect pest of rice in Thailand.

Abstract

Physiological traits such as photosynthetic rate (A), stomatal conductance (g_sw), and intrinsic water-use efficiency (iWUE) are influenced by photosynthetically active radiation (PAR); however, their specific effects on individual plant species remain insufficiently studied. The objective of this study was to evaluate A, g_sw, and iWUE in young and mature leaves under varying PAR levels (400, 1000, and 1600 µmol m⁻² s⁻¹) across six Indonesian medicinal plants: Dalbergia latifolia (DL), Murraya koenigii (MK), Murraya paniculata (MP), Syzygium cumini (SC), Syzygium polyanthum (SP), and Swietenia mahagoni (SM), to better understand their light-intensity tolerance for cultivation purposes. Data analysis revealed that A was significantly affected by species, leaf age, and PAR, whereas g_sw and iWUE were influenced only by species and PAR (α = 0.01). The results highlight the broad adaptability of M. koenigii, which may perform well across a wide range of light conditions. In contrast, S. cumini, D. latifolia, and S. mahagoni appear to be more shade-tolerant, while M. paniculata and S. polyanthum seem better adapted to high-light environments, potentially favoring drier habitats due to their elevated iWUE under intense light. Collectively, these findings provide valuable insights to guide sustainable cultivation and conservation strategies for Indonesia’s medicinal plant resources.

Abstract

Chlorella sp. has garnered attention as a sustainable feedstock to produce bioactive compounds with potential applications in energy, pharmaceuticals, and agricultural sectors. The commercial viability and sector expansion require a streamlined cultivation process. The chemical nutrient media utilized remain a bottleneck and contribute appreciably to the downstream costs. The study aimed to develop a cheaper and environmentally friendly technique for culturing Chlorella sorokiniana UTEX 1230 using goat manure waste. The nitrified air-dried goat manure was aerobically fermented with efficient microbes to augment the nutrient bioavailability. The biomass concentration, biomass productivity, and specific growth rate of C. sorokiniana UTEX 1230 were significantly higher in GME10% compared to commercial M8 medium. Moreover, the doubling time was significantly lower for GME10% medium compared to the commercial M8. Carbohydrates were found to be higher in commercial M8, whereas protein content was higher in GME10%. The carbohydrate and protein content showed a clear association with nitrogen concentration in the media, which confirms the role of nitrogen in the synthesis of carbohydrates and proteins in microalgae. These findings provide an insight into the possibility of using animal wastes such as goat manure as a surrogate culturing medium for C. sorokiniana. The GME medium is environmentally friendly, as it enhances sustainability by recycling nutrients and reducing the nutrient input costs associated with microalgae biotechnology.
