The MarVal project is divided into six work packages (WP). In WP-1 (resources), selected marine biomass will be processed aiming at isolation of biopolymers. In WP-2 (microorganisms), bacterial isolates and whole bacterial communities will be selected from enrichment on biomass substrates, and subsequently genome sequenced. In WP-3 (biocatalysis), enzyme targets will be selected based on functional and in silico screening of microorganisms identified in WP-2. Single enzymes, pathways, as well as microorganisms will be subjected to modelling and simulation for optimization through design and redesign in WP-4 (modelling). In close interaction with end-product industry, the products will be tested in WP-5 for applications. WP-6 will focus on societal impact of the utilization and the stakeholders’ attitudes.
