The Role of Benthic Organisms in the Degradation and Preservation of Planktonic Lipids in Coastal Sediments

小行星9633603 将在受控的实验室条件下研究几种脂性脂质化合物的降解速率常数。 底栖动物的活动是造成实地测量的氧化和缺氧沉积物剖面速率常数之间差异的最可能因素。动物可以改变好氧/缺氧与缺氧条件下的生物矿化效率和中间产物的形成表明，降解遵循不同的途径。研究将特别考虑底栖动物对氧化和缺氧条件之间降解的影响。底栖动物不同影响下放射性示踪剂的降解速率和途径。进一步深入研究孵育实验期间产生的代谢物的结构，将提供这些重要化合物降解的更详细的情况。

9633603 SUN Degradation rate constants for several planktonic lipid compound will be investigated under controlled laboratory conditions. Activity of benthic animals was the most likely factor causing the difference observed between rate constants oxic and anoxic sediments profiles measured in the field. Animals can alter oxic/anoxic versus anoxic conditions in remineralization efficiency and formation of intermediate products show that degradation follows different pathways. Research will specially consider the effects on degradation between oxic and anoxic conditions caused by benthic animals. Radiolabelled tracers degradation rates and pathways under various influences of benthic animals. Further intensive study of the structure of metabolites produced during incubation experiments will provide a more detailed picture of the degradation of these important compounds.
