Summary: This study aimed to improve the thermodynamic performance of nanoliposomes (NLs) by using a second-layer coating biopolymer, fucoidan (F), along with chitosan (CS), to control the delivery and bioavailability of catechin (C) and juglone (J). The developed F/CS-conjugated JC-NL (F-CS-JC-NL) showed enhanced stability under different pH and ionic strengths, and had the highest encapsulation efficiency of juglone (95.47%) and catechin (90.88%). In vitro digestion experiments demonstrated that F-CS-JC-NL significantly reduced compound leakage in the gastrointestinal tract and provided better controlled release and bioavailability of juglone/catechin compared to other formulations. This study provides a novel nanoliposomal delivery carrier with enhanced physicochemical stability and controlled release for delivering functional ingredients.

Summary: In this study, a novel sustained release system (VCSB-Zn(II)) was developed to enhance the utilization of zinc trace elements. VCSB exhibited superior chelation capacity for Zn2+ compared to chitosan, with a chelation capacity 1.7 times higher at 50.96 mg/g. The system demonstrated excellent sustained release performance in simulated gastric fluid, reaching a cumulative release rate of 77.81% with higher C=N content. This zinc sustained release system shows promising potential for trace element supplementation in animals.

Summary: This study explored cost-effective and eco-friendly strategies for native soil phosphorus (P) solubilization, including using silicon (Si)-rich agro-wastes as a Si source and phosphate solubilizing microorganisms (PSM). The results showed that both strategies significantly increased the solubility of P in the soil, as well as the activity of soil enzymes and microbial biomass P. These findings suggest that utilizing agro-wastes as Si sources can complement expensive P fertilizers and address waste disposal issues in a sustainable manner.

Summary: The present study evaluated the synergistic properties of several synergists with deltamethrin (DLM) and ivermectin (IVM) against resistant tick populations. The results showed that the combinations of piperonyl butoxide (PBO) and IVM, as well as verapamil (VER) and IVM, significantly enhanced the effectiveness of IVM against IVM-resistant ticks. Additionally, the combination of PBO and DLM also reduced the resistance of DLM-resistant ticks. The study highlights the need for resistance management strategies and the use of synergists to control acaricide-resistant ticks.

Summary: Bacteria release volatile organic compounds (VOCs) into the environment, which have various effects on plants, including promoting growth, suppressing pathogens, and acting as signaling molecules. Some VOCs also exhibit antimicrobial and pesticidal activities. Different bacterial species produce different VOCs, with some contributing to plant growth promotion. Understanding the mechanisms by which VOCs affect plant genes and metabolic pathways is still a topic of ongoing research.

Summary: A passive composting method using a hybrid Bacillus commune and cow dung slurry for municipal solid waste was investigated, where four Bacillus strains were mixed with cow dung in different ratios. The temperature (ambient and pile) triggered physico-chemical changes in the compost mix, and the quality of the finished compost was tested after two seasons. Adding Bacillus commune and cow dung slurry during the peak summer season accelerated degradation and resulted in enriched compost. Various parameters such as color, pH, C/N ratio, organic carbon, conductivity, density, NPK availability, and phytotoxicity assays justified the effectiveness. Microbial diversity and suitable seasonal conditions play an important role in the waste degradation process and compost maturity.

Summary: This study analyzed the effect of granulation on the physico-functional properties of 'Itaborai' sweet orange. The results showed that granulated juice sacs had a thicker cell wall and higher respiration rate compared to healthy fruit. Granulated citrus juice sacs contained a higher amount of galacturonic acid and had diminished β-glucosidase activity, resulting in cellulose deposition. Additionally, healthy fruit exhibited higher ferrous ion-chelating activity and lower lipoxygenase activity than granulated fruits. The study suggests that granulation might be related to pectin metabolism.
