Background: The global rise of antimicrobial resistance has accelerated the search for sustainable and eco-friendly therapeutic alternatives. This study evaluates fish gut waste (FGW) as a low-cost, renewable substrate for producing antifungal peptides through the proteolytic activity of Serratia liquefaciens NRC1.

Result: Optimization of protease production using statistical designs resulted in a fourfold increase in enzyme yield.

The aim of this review is to highlight the role of semisolid systems as vehicles for nanovesicles and nanoparticles. In general, nanotechnology plays a critical role in facilitating the delivery of therapeutic agents to their active sites, and several nanocarrier systems have been explored for the topical administration of active components. The major disadvantage of the prepared nanosystems is their low viscosity, which reduces the time needed for enough absorption and negatively affects their stability and bioavailability.

Food coatings are efficient preservative measures, a crucially needed approach to meet hunger growth as well as food management. In the current study, the construction of an efficient coating using alginate polymer fortified with antioxidant rice straw-hemicellulose hydrolysate was examined. Rice straw hemicellulose fraction was extracted under thermal alkaline conditions with a recovery percentage of 15.

The carbonization of wool fleece (WF) is conducted to remove the adhered vegetable matter (VM) from contaminated WF using sulfuric acid, followed by drying and backing. This process has a deteriorative effect on WF and requires a tremendous quantity of water for rinsing WF after carbonization to remove any HSO residuals. Herein, we propose an alternative eco-friendly water-saving process for the removal of VM from WF using enzymes.

Production and potential application of chitooligosaccharide is reported in this study. Chitooligosaccharide was produced by enzymatic hydrolysis of chitosan using Bacillus cereus chitosanase. The chitooligosaccharide was characterized, and its prebiotic activity together with the antioxidant activity were evaluated and compared to marketed standard and chitosan.
