Summary: The composition of avian eggshell membranes is similar to the extracellular matrix of cells, making them potential biomaterials for tissue engineering applications. However, there are challenges in optimizing the process conditions for extracting collagen, the main component of eggshell membranes. This study used an enzymatic method to extract collagen and optimized the process using the one-factor-at-a-time technique. The optimized conditions resulted in a maximum yield of 56% collagen using 350 U/mg pepsin concentration at pH 3 for 9 days, which has not been reported before. The extracted collagen was characterized using various techniques and the results showed changes in morphology and topology during the extraction process. The process optimization and characterization of eggshell membrane-derived collagen can contribute to the development of biomaterials for tissue regeneration.

Summary: Porous hydroxyapatite was prepared by reacting eggshell with phosphoric acid and a foaming agent. It was then composited with collagen derived from Acetobacter xylinum fermentation, Oreochromis niloticus fish skin extraction, and commercial-grade collagen. The bio composite materials showed promising physical-mechanical-thermal properties for bone tissue engineering, drug delivery, and tissue regeneration. The addition of collagen significantly improved the mechanical strength and thermal shock absorption performance of the porous hydroxyapatite matrices.

Summary: In this study, eggshells treated at 800 degrees C were found to be highly efficient adsorbents for fluoride removal with a maximum adsorption capacity of 258.28 mg/g at pH 7 and 25 degrees C, 18 times larger than that of activated alumina. The fluoride removal mechanism involved the formation of calcium fluorite (CaF2) as revealed by XRD and X-ray photoelectron spectroscopy analysis. The presence of anions was found to decrease fluoride adsorption, with the impact following the order: HPO43- > HCO3- >> SO42- > Cl-.
