Article Abstract
The purpose of this study was to investigate the antimicrobial activity and mechanisms of N-lauroyl arginate ethyl ester (LAE) against and subsp. . The minim inhibitory concentrations of LAE against and were found to be 400 and 25 μg/ml, respectively. Loss of intracellular protein and nucleic acid increased significantly, and membrane permeability reached 76.28, 54.29 and 85.20%, respectively, when 400 μg/ml of LAE was applied to the hyphae and spores of and to . Flow cytometry showed that LAE reduced the membrane potential, and the depolarization ratios of and were 98.19 and 97.25% (< 0.05), respectively. Transmission electron microscopy photos revealed that LAE caused a rough surface, irregular cellular organelles, protoplast shrinkage, intracytoplasmic coagulation and empty cavities in all three cell types. These results showed that LAE had notable ability to damage the structure of fungal and bacterial cells, making it a possible alternative chemical for use in the preservation of fruits and vegetables.

Designing supramolecular gelators with targeted properties is very difficult and mainly relies on structural modifications of known gelator molecules. However, very often, even minor modifications can result in the complete loss of gelation capabilities. In the present work, we have studied the influence and role of the silver nanoparticles (AgNPs) and trisodium citrate (TSC) additives on the self-assembly process of alanine derivative gelator (CAla) and intermolecular interactions resulting in hydrogel systems of enhanced stability and sustainability.

With the improvement of people's living standards and health awareness, reducing salt, sugar, and fat is gradually becoming the mainstream trend. In this work, we delved into the development of an innovative taste enhancer, N-lauroyl theanine (NLT), and its taste presentation mechanism. NLT was synthesized in the aqueous phase by enzyme-catalyzed and direct-heating methods using food-grade enzymes in yields of up to 64.

To satisfy the demands of the food industry, innovative flavor enhancers need to be developed urgently to increase the food flavor. In our work, N-lauroyl phenylalanine (LP) was prepared from phenylalanine (l-Phe) and lauric acid (Lau) in water through the use of commercial enzymes (Promatex, Sumizyme FP-G, and Trypsin), and its flavor-presenting properties and mechanism were investigated. The highest LP yields obtained under one-factor optimized conditions were 61.

With the increasing prevalence of drug-resistant bacterial infections and frequent occurrences of slow wound healing, the development of novel antibacterial wound dressings has become a serious challenge. Hydrogel dressings have attracted extensive attention on wound healing due to their unique three-dimensional network structures and properties. However, it is a challenge to develop natural long-acting antibacterial hydrogels with multiple functions such as excellent cell affinity, wet adhesion and mechanical properties.
