The Life Seacolours Project of the Banco Español de Algas (BEA) based at the University of Las Palmas de Gran Canaria competes to be the best of the best of Life Projects of the European Union, and could achieve this, because it has managed to create an ecological colouring that could revolutionise the textile industry.
The synthetic pigments and stains used today are pollutants and produce non-degradable residues. The scientific director of BEA said this week “We have to look for alternatives. Our role has been to select strains of microalgae that accumulate a large amount of pigments that we can manage and maintain under crop conditions, producing biomass and pigments with the aim of extracting them for later applications.”
The algae offer a wide range of colours, from the green ones obtained from chlorophyll to the orange and yellow ones of the carotenoids, through the blue and red pigments from the phycobiliproteins.
