多糖构成了海洋系统中重要的碳库，但这些化合物的命运和降解仍然未知。它们部分来自当地的生产，而在沿海地区，它们部分来自陆地，来自陆地的淡水径流。本研究的目的是测试高通量多糖谱分析在沿海海洋环境的年代沉积物岩心中对植物和藻类细胞壁化合物的适用性，检查细胞壁多糖的保存情况，并探索它们作为时间环境变化代用物的潜力。保存下来的化合物和生物遗骸通常被用作古环境的代用物，因为不同化合物的数量和组成可以提供对过去环境条件的洞察，并且高度寻求报告环境变化的新方法。
Polysaccharides constitute an important carbon pool in marine systems, but much is still unknown about the fate and degradation of these compounds. They are derived partly from production in situ, and in coastal areas, they are partly terrestrially derived, originating from freshwater runoff from land. The aim of this study was to test the applicability of high-throughput polysaccharide profiling for plant and algal cell-wall compounds in dated sediment cores from a coastal marine environment, to examine the preservation of cell-wall polysaccharides and explore their potential as proxies for temporal environmental changes. Preserved compounds and remains of organisms are routinely used as paleoenvironmental proxies as the amount and composition of different compounds that can provide insight into past environmental conditions, and novel means for reporting environmental changes are highly sought.
