Since the beginning of marine bioprospecting, the ocean and its different ecosystems have been considered valuable sources to explore new raw materials and natural products, as well as an engine of the economy due to its great potential for innovation and sustainable economic growth.

The organic content of jellyfish is mainly collagen.
The natural and hydrolyzed collagen obtained mainly from the umbrela and oral arms of the species Rhizostoma pulmo and Cotylorhiza tuberculata, jellyfish very abundant in the Spanish Mediterranean, is considered an innovative and sustainable alternative to collagen derived from the skin and bones of terrestrial mammals such as cattle and pigs.
In some countries, collagen from jellyfish is used as a raw material for applications that significantly improve the well-being and health of future generations, such as nutraceuticals and cosmeceuticals.
In addition, it is a biomaterial that can be used, due to its low immunogenicity and high biocompatibility, in tissue engineering.

In this context, the COLMED project aims to use jellyfish as an innovative source of collagen, contributing to reducing the socio-economic impacts generated by their proliferations in the tourism and fishing sectors. Likewise, COLMED seeks to convert the stigma of problematic and threatening species for society into a useful and valuable species within the framework of blue biotechnology, circular economy and zero waste.
