The overall objective of WP2 is to preserve the inherent quality and safety of the biomass produced in WP1 by using optimized stabilization and/or processing technologies in order to supply stable and valuable ingredients and products for the market. It will be achieved through 4 interconnected tasks with the following objectives: O1) to evaluate stability of raw materials and suggest solutions for storage and stabilization to prevent quality deterioration of the material; O2) to develop and optimize biotechnological solutions for fresh and/or stabilized raw materials for separation into valuable fractions or final products; O3) to characterize fractions and products and define the most optimal stabilization solutions taking into consideration their use in different segments of the market; O4) to ensure microbial biosafety by fine meshed analysis of the microbial community of input to and output from WP2.
