大型藻类是生物质资源，代表了完全用于人类消费或在一些提取（主要是胶体）后用于食品添加剂和/或用于能源生产的有价值的原料。为了更好地发展藻类部门，重要的是根据其生物化学特性确定大型藻类为食品和/或能源工业生产这些增值分子的能力。在这项研究中，从法国布列塔尼海岸（法国）获得的10个大型藻类。全球生化组成（蛋白质，脂质，碳水化合物，纤维），存在和特性的附加值分子（藻酸盐，多酚）和这些藻类的生化甲烷潜力进行了测定。关于其生化组成，Palmaria palmata是有趣的食物（营养丰富）和厌氧消化（0.279 LCH 4/gVS）。海藻酸钠的提取量为242 g/kgTS，甘露糖醛酸与古罗糖醛酸的M/G = 1.4;海藻多酚的提取量为19.8 g/kgTS。(c)2013爱思唯尔有限公司保留所有权利。
Macroalgae are biomass resources that represent a valuable feedstock to be used entirely for human consumption or for food additives after some extractions (mainly colloids) and/or for energy production. In order to better develop the algal sector, it is important to determine the capacity of macroalgae to produce these added-values molecules for food and/or for energy industries on the basis of their biochemical characteristics. In this study, ten macroalgae obtained from French Brittany coasts (France) were selected. The global biochemical composition (proteins, lipids, carbohydrates, fibers), the presence and characteristics of added-values molecules (alginates, polyphenols) and the biochemical methane potential of these algae were determined. Regarding its biochemical composition, Palmaria palmata is interesting for food (rich in nutrients) and for anaerobic digestion (0.279 LCH4/gVS). Saccharina latissima could be used for alginate extraction (242 g/kgTS, ratio between mannuronic and guluronic acid M/G = 1.4) and Sargassum muticum for polyphenol extraction (19.8 g/kgTS).
