Summary: This study examined the antibacterial effects of Mentha longifolia essential oil and pulegone in edible coatings on the growth of Staphylococcus aureus, Listeria monocytogenes, and Escherichia coli in cheese. The results showed that the addition of these compounds significantly reduced bacterial growth during storage. Increasing the concentration of chitosan, M. longifolia, and pulegone in the coatings further decreased the bacterial population, with pulegone exhibiting a stronger effect. Overall, the findings suggest that M. longifolia essential oil and pulegone, combined with alginate and chitosan coatings, have antibacterial effects against S. aureus, L. monocytogenes, and E. coli in cheese.

Summary: This study focuses on the fabrication and characterization of composite scaffolds based on polycaprolactone (PCL) and cerium (Ce)-containing powders. The composite scaffolds showed good biological activity and antibacterial effect. The scaffolds were composed of either dimensionally homogeneous fibers or mixtures of fibers with a wide size distribution and beads of different shapes. The immersion in simulated body fluid (SBF) triggered the degradation of PCL, mainly through cracks and gaps. The composite scaffolds exhibited excellent biocompatibility, with the samples consisting of PCL and Ce-doped calcium phosphates showing superior performance.
