Prince Edward Island (PEI) has strong fishing and tourism sectors that are connected through waterways. These waterways are being choked by nuisance algae such as sea lettuce (Ulva lactuca), whose growth is promoted by nitrogen runoff. Sea lettuce (Ulva lactuca) is rich in nutrients and chemicals with medicinal and health-promoting effects, which make them valuable for food supplements, biostimulants, and bioactive compounds. The observed benefits of sea lettuce are due to the presence of Ulvan. Ulvan is a cell wall polysaccharide made of sulfated rhamnose, uronic acid and xylose contributing 9-36% dry weight of biomass of sea lettuce. The focus of this project is to develop and enhance a process through which this nuisance crop can be harvested and converted into an innovative value-add product, a bio-based crop stimulant. A hydrothermal based process is investigated for the extraction of valuable compounds from the sea lettuce. The process will be optimized for higher yield of targeted compounds. Additionally, an innovative semi-continuous system will be developed for processing sea lettuce. The two-fold benefit of this enhanced process will create a clean waterway for tourism and marine life and in turn, produce a non-chemical crop growth stimulant. The partner will support the project results by commercializing the extract and both selling it to its clients and using it within its own farm. The system can be utilized around the world where sea lettuce exists, thereby creating additional prospects for exporting know-how. The results of the research will help the partner organization make investment decisions for the large-scale development of this technology in Canada.

爱德华王子岛 (PEI) 拥有强大的渔业和旅游业，并通过水路相连。 这些水道正被诸如海生菜（Ulvalactuca）等令人讨厌的藻类所堵塞，而氮径流会促进海生菜的生长。海生菜 (Ulvalactuca) 富含营养物质和化学物质，具有药用和促进健康的作用，这使其成为食品补充剂、生物刺激剂和生物活性化合物的重要原料。海生菜所观察到的好处是由于绿藻万的存在。绿藻万是由硫酸化鼠李糖、糖醛酸和木糖组成的细胞壁多糖，占海生菜生物量干重的 9-36%。该项目的重点是开发和改进一种工艺，通过该工艺可以收获这种有害作物并将其转化为创新的增值产品，即生物基作物兴奋剂。研究了从海生菜中提取有价值化合物的水热工艺。该工艺将进行优化，以提高目标化合物的收率。此外，还将开发一种创新的半连续系统来加工海生菜。这一增强过程的双重好处将为旅游业和海洋生物创造一条清洁的水道，进而产生一种非化学作物生长刺激剂。合作伙伴将通过将提取物商业化并将其出售给客户并在自己的农场内使用来支持项目成果。 该系统可在世界各地有海生菜的地方使用，从而为出口技术创造更多前景。研究结果将帮助合作伙伴组织为该技术在加拿大的大规模开发做出投资决策。
