Optimizing cultivation for Ulva refinery

News: May 15, 2020

Seaweeds contain many potentially worthwhile compounds. To increase the economic potential of refining seaweed biomass, the content of the compounds of interest should be maximized, potentially through optimization of cultivation conditions. In this study, the monosaccharides present in the potential high-value component ulvan changed significantly with higher fractions of iduronic acid at intermediate irradiance and ambient nitrate conditions. The results could potentially be utilized to coax the ulvan towards specific bioactivities, and thus have a considerable impact on a potential biorefinery centered around Ulva.
