Microalgae offer clear advantages over terrestrial species in terms of rapid production, short generation time, adaptation capacity-metabolic plasticity, huge biodiversity and a panoply of commercial applications, including cosmetics and aquaculture, the targets of Algae4 A&B project. These promising organisms are an important reservoir of novel and valuable bioactive compounds that are largely unexplored, being proteins one of the major constituent (around 25–40% of the dry weight). Furthermore, a broad spectrum of biological properties (eg: antioxidants, antihypertensive, anticoagulant, antitumor, immune-stimulating…) has been attributed to microalgae bio-functional proteins/enzymes and peptides. Omics technologied application to microalgae is just beginning to emerge in the last years and few proteomics studies exist. There is no doubt that this is a niche with potential for biotechnological exploitation that deserves attention and in the context of Algae4A&B project we are contributing to fill this gap.
ProtMar (Recombinant Protein and Biosensors Platform at CCMAR) is assisting Algae4A&B project in a proteomic approach through the application of advanced proteomic technology to microalgae. General proteomics workflow (sample preparation/MS analysis/ data processing and bioinformatics) has been applied to microalgae and the main challenges are being identified and optimized. Our goal is to identify/characterize new microalgae compounds (proteins) with biotechnological applications by proteome mapping and quantitative proteomic.
