“…HC extracted from chicken legs by enzymatic action (proteases) [106] and skin of Rana chensinensis by acid hydrolysis [107] exhibited high solubility, angiotensin-converting enzyme inhibition, and antioxidant activity. Chicken feet treated with papain enzymes at different temperatures (4, 30, and 56 °C) and different extraction times (20, 24, and 28 h) showed functional properties such as water and oil retention capacity as well as emulsifying and foaming properties [108,109].…”

Hydrolyzed collagen (HC) is a group of peptides with low molecular weight (3–6 KDa) that can be obtained by enzymatic action in acid or alkaline media at a specific incubation temperature. HC can be extracted from different sources such as bovine or porcine. These sources have presented health limitations in the last years. Recently research has shown good properties of the HC found in skin, scale, and bones from marine sources. Type and source of extraction are the main factors that affect HC properties, such as molecular weight of the peptide chain, solubility, and functional activity. HC is widely used in several industries including food, pharmaceutical, cosmetic, biomedical, and leather industries. The present review presents the different types of HC, sources of extraction, and their applications as a biomaterial.

“…The characteristics of extracted collagen depend on the raw material and the extraction conditions. Collagen extraction is achieved by solubilization in aqueous solutions, typically dilute acid solutions 88 or dilute acid solutions added with proteolytic enzymes, 84,89 are used, each method comes with advantages and disadvantages (Table 1).…”

Materials used for wound care have evolved from simple covers to functional wound dressings with bioactive properties. Electrospun nanofibers show great similarity to the natural fibrillar structure of skin extracellular matrix (ECM); therefore, by mimic, the morphology of ECM, nanofibers show high potential for facilitating the healing of skin injuries. Besides morphology, scaffold composition is another important parameter in the production of bioactive wound dressings. Collagen type I is the main structural protein of skin ECM is biocompatible, biodegradable, and its extraction from animal sources is relatively simple. The fabrication of electrospun wound dressings based on collagen and its blends have been studied for skin tissue engineering applications. This review focus on the new advances of collagen electrospun materials for skin wound treatment. It summarizes the recent research on pristine collagen, collagen blends, and collagen surface modifications on nanofibers mats. Finally, the strategies for three‐dimensional nanofibers production will also be discussed.

In this study, a novel feather-degrading bacteria B. amyloliquefaciens KB1 was isolated from chicken farm bed (CFB), identified by morphological, physico-biochemical tests followed by 16s rDNA analysis. Among observed isolates, bacterial isolate (KB1) showed the highest degree of feather degradation (74.78 ± 2.94 %) and total soluble protein (205 ± 0.03 mg/ g). Using the same species of bacteria, the optimum fermentation condition was found at 40 oC, pH 9, and 1 % (w/v) feather concentration that produced 260 mg/ g of soluble protein and 86.16 % feather degradation using response surface methodology in a Box-Behnken design space. The obtained hydrolysates exhibited bioactive properties. The amino acid profile showed the increase in concentration of essential amino acid compared with feather meal broth. The selection of safe screening source of this new bacteria in CFB produced hydrolysates with enhanced bioactivity applicable for food, feed, and cosmetic applications along with environmental remediation.
