海藻是生物精炼和生物技术应用的宝贵资源，但其高含水量是一个经常性问题，也是其可持续利用的关键瓶颈之一。作者最近描述了增加海带干物质含量的处理。然而，大型藻类是一个极其多样化的生物群体，物种之间的组成变化可能会影响特定处理的效果。在这项研究中，潜在的脱水处理，包括干燥，渗透介质，和有机和无机酸的应用程序，所有随后的螺旋压已被测试对其他两种海带（海带hyperborea和海带latissima）和红色海藻（棕榈）。这些物种的脱水条件进行了鉴定，并将数据与以前的L。毛地黄在所有感兴趣的性状上，物种之间存在显着差异。然而，脱水是高度依赖于特定的相互作用与治疗和季节的收集。然而，通过空气干燥或酸处理后再进行螺旋压榨，褐海藻的干物质含量得到了广泛而成功的提高。棕榈的结果截然不同，特别是在果汁产量方面。酸处理对该品种无脱水作用，但收获后立即进行螺旋压榨可提高干物质含量。这里提供的数据表明，脱水预处理需要针对待加工的海藻类型;这是未来使用这种可持续生物质资源的重要知识。
Seaweeds can be a valuable resource for biorefinery and biotechnology applications, but their high water content is a recurrent problem and one of the key bottlenecks for their sustainable use. Treatments to increase dry matter content of the kelp Laminaria digitata were recently described by the authors. However macroalgae are an extremely diverse group of organisms and compositional variation between species may influence the effects of particular treatments. In this study, potential dewatering treatments including drying, osmotic media, and the application of both organic and mineral acids all followed by screw-pressing have been tested on two other species of kelp (Laminaria hyperborea and Saccharina latissima) and a red seaweed (Palmaria palmata). Conditions that dewatered these species were identified and the data have been combined with the previous results for L. digitata. There were significant differences between species across all the traits of interest. However dewatering was highly dependent on specific interactions with both treatment and season of collection. Nevertheless, the dry matter content of brown seaweeds was widely and successfully increased by air drying or acid treatment followed by screw-pressing. The results for P. palmata were quite different, particularly with regard to juice production. For this species, acid treatment did not result in dewatering, but dry matter content could be increased by screw-pressing immediately after harvest. Together the data presented here demonstrate that dewatering pre-treatments need to be specific for the type of seaweed to be processed; important knowledge for the future use of this sustainable biomass resource.
