Abstract

Collagen and collagen fibers have been widely documented as a potential and competitive biomaterial for medical applications. However, the searches for safe and realistic new collagen sources are still underway. Currently, fishery by-products (scales), a promising collagen source are usually discarded. In the present study, in vitro fibril-forming ability of the extracted fish scale collagen is reported. The aim of the investigation was to evaluate the concomitant comparison of fibril-forming abilities and characteristics of acid and pepsin soluble collagens fromthe scales of Indianmajor carp catla (Catla catla) and rohu (Labeo rohita). The extracted collagenswere characterized as type I,with a total yield of 2.80–4.11% (w/w). Denaturation temperature determined for all collagens were between 35.9 and 37.7 °C. All collagens exhibited high solubility in acidic pH and low NaCl concentrations. SEMclarified the lyophilized collagens and their fibril-forming capacity. Amino acid content and radical scavenging efficacy were also analyzed for the extracted collagen. The results revealed that extracted scale collagen from a renewable biological source could be used as biomaterials in various sectors. It might be suitable for preparing collagen gel for biomedical devices or as a scaffold for cell culture because of its high stability and fibril formation capacity.
