Using either freshly pulped or preserved seaweed biomass for the extraction of protein can have a great effect on the amount of protein that can be extracted. In this study, the effect of four preservation techniques (frozen, freeze-dried, and air-dried at 40 and 70 °C) on the protein extractability, …

Marine debris is a growing global problem. Due to the wide ocean dynamics worldwide, predicting the transport of floating marine debris, such as plastic, is difficult. Although large-scale distribution patterns and accumulation zones are recognised and reproduced by numerical models, small-scale prediction …

Vanuit het ZEEVIVO project werd in werkpakket B, Bioraffinage, onderzoek gedaan naar het opwaarderen van eiwit uit zeewier. De hoofdvraag was: Hoe is uit zeewier een commercieel interessant eiwitconcentraat te extraheren met een eiwitgehalte van tenminste 60%? Om deze vraag te beantwoorden zijn optimalisatieproeven …

Bergen city centre is prone to both subsidence and flooding. With a predicted increase in precipitation due to climate change, a higher proportion of rainfall becomes surface runoff, which results in increased peak flood discharges. In addition, it has been predicted that sea-level rise and increasing …

De kweek van vis en de vraag naar visvoer groeit wereldwijd enorm. Voor een verdere duurzame groei is de visvoer industrie op zoek naar alternatieve eiwitbronnen die duurzaam zijn en zo min mogelijk concurreren met bronnen geschikt voor humane consumptie. Eiwit uit zeewier kan in potentie een duurzaam …

In werkpakket A, Zeewierteelt, werd onderzocht wat het effect is van de nitraatconcentratie op de groei en eiwitgehalte van de zeewiersoorten Saccharina latissima en Ulva lactuca. Bij de laatste soort werd ook gekeken naar de aminozuursamenstelling. Hogere nitraatconcentraties zorgden bij beide zeewiersoorten …

Maize cultivation in Ghana has been ongoing for centuries. Maize production in Ghana, is predominantly done under rain-fed conditions by smallholder farmers. The agro-ecological zones for maize cultivation in Ghana are grouped into four; the coastal savannah, forest zone, transition zone and the Guinea …

Spatial and temporal patterns in submarine groundwater discharge (SGD) of nitrate in a high-energy sandy beach system on Spiekeroog Island were examined utilizing UV photometry. SGD as pathway of nitrate was studied to gain better understanding of the variability of nitrate discharge and the factors …
