This study investigates the incorporation of melanin extracted from pecan nutshell residues into a polyacrylonitrile (PAN) matrix during electrospinning microfiber membranes. Melanin concentrations 0.5, 2.0, and 5.0% w/w were incorporated to enhance physicochemical biological properties fibers. The melanin-loaded PAN fibers exhibited significant antioxidant activity against DPPH ABTS radicals, with scavenging rates ranging 46.58% 62.77% 41.02% 82.36%, respectively, while unmodified showed no activity. Furthermore, membranes demonstrated antimicrobial effects. also an important enzyme inhibition collagenase (37%), hyaluronidase (22%), tyrosinase (36%), elastase (33%). Molecular docking studies reveal different potential amino acids active sites aging enzymes that interact strongly pigment, particularly collagenase, followed by hyaluronidase, tyrosinase, elastase. These results suggest novel possess promising bioactive applications in skin-care applications.

Oysters are one of the largest marine shellfish species worldwide. However, oyster shells treated as waste, accumulating on coastal shores and seriously polluting ecosystem. In this study, a composite microbial agent was developed using calcined shell powder, Beauveria bassiana spore ecological chitosan. To release active ingredients, were by calcination. The optimal application ratio determined detecting tomato growth indicators. Application optimized to vineyards increased 100-grain weight, carotenoids, total amino acids 10.55%, 8.71%, 29.40%, respectively. Further detection soil population changes showed that abundance diversity populations, promoting metabolism bacterial acids, polysaccharides. These findings suggest not only enhanced plant fruit quality, but also enriched communities.
