Extraction and Characterisation of Type I Collagen from the Scales of Redcoat Sargocentron rubrum

Abstract: Collagen, one of the most important biopolymers, is widely used in the food and pharmaceutical industries due to its functional and technological properties. Alien species, especially of Indo-Pacific origin, entering Mediterranean waters can exert pressure on native species and cause ecological and economic effects. In this study, we produced collagen from the scale of Sargocentum rubrum to bring this species to the economy and to reduce the pressure on our infested marine ecosystem as a surplus value. Acid-soluble collagen was extracted; a characteristic sodium dodecyl SDS-PAGE gel electrophoresis profile for type I collagen was obtained from the S. rubrum scales. The yield of collagen extracted from the scales of S. rubrum by the ASC method was calculated as 11.2%. The results of the analyses show that the collagen obtained from S. rubrum scales was Type I collagen with high yields. It has been proved that non-economic alien species as S. rubrum used in our study can be used as an alternative source instead of terrestrial animal collagen. The results obtained show that collagen obtained from S. rubrum scales can be a good alternative source for biomedical and other cosmetic industries.
