项目摘要
ABSTRACTOCE-0080782The question of the origins, composition, and reactivity of the dissolved organic matter that is found throughout the world ocean is one of central importance in chemical oceanography. In particular, there has been much speculation about the possible importance of the reaction products of amino acids and reducing sugars (so-called amino sugars) and their relation to the biochemistry of marine bacteria. In this project, researchers at the University of South Carolina will determine the origins, abundance, and composition of amino sugars in marine organisms and in particulate, colloidal, and dissolved organic matter. Three component efforts will be undertaken. First, the principal investigator will conduct a survey of the abundance and composition of amino sugars, neutral sugars, and D/L amino acids in marine organisms, POM, colloids, and DOM from the Pacific and Atlantic Oceans. Then, the relative reactivities of amino and neutral sugars will be evaluated and compared in an assessment of their use as diagenetic (water column and sediment reaction) indicators. And finally, a series of field surveys and decomposition studies will be used to assess the importance of bacteria as sources of amino sugars and DOM in seawater.
海洋中溶解有机物的来源、组成和反应性是化学海洋学的核心问题之一。 特别是,人们对氨基酸和还原糖(所谓的氨基糖)的反应产物的可能重要性及其与海洋细菌生物化学的关系进行了许多猜测。 在这个项目中,南卡罗来纳州大学的研究人员将确定海洋生物以及颗粒、胶体和溶解有机物中氨基糖的来源、丰度和组成。 将开展三项工作。 首先,首席研究员将对太平洋和大西洋的海洋生物、POM、胶体和DOM中的氨基糖、中性糖和D/L氨基酸的丰度和组成进行调查。 然后,将评价和比较氨基和中性糖的相对反应性,以评估它们作为成岩(水柱和沉积物反应)指标的用途。 最后,一系列的实地调查和分解研究将被用来评估细菌作为海水中氨基糖和DOM来源的重要性。
