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, …

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 …

This study has been conducted to estimate the ecological impact of wild harvesting Ulva spp. biomass on its population in the Dutch Wadden Sea. The purpose is to give an advice about the ideal time (on the level of population recovery) to wild harvest 1000 kilogram Ulva spp. from the Dutch Wadden Sea. …

This thesis project has been carried out at VHL (Van Hall Larenstein University of Applied Sciences) and consists of three different parts; the first part is an experiment in which during 20 days of cultivation the optimum nitrate concentration for protein production in Ulva lactuca is sought. U. lactuca …

In this study, various extraction methods were compared based on their ability to extract both free amino acids, and free 5’-monophosphate nucleotides from the seaweed Saccharina latissima. Based on the results, extraction at room temperature with Milli-Q over 24 hours was chosen as the method of choice, …
