REU: Chemical and Microbiological Characterization of Phytoplankton Decay

这项研究包括以实验室为基础的浮游植物腐烂调查，其中定量的化学测量与微生物活动的检查同步进行。这些关于实验室中选定藻类的信息将评估跟踪微生物活动的最合适的方法。该项目的目标是：1)确定浮游植物在实验室的水柱中在缺氧和缺氧环境下降解时的变化。2)探讨微生物代谢产物与藻类碳在分解过程中的转化关系。3)比较植物碎屑类有机质的变化率与微生物活性，以构建单个和特定类有机质的稳定性指数。

This study comprises laboratory based investigation of phytoplankton decay in which quantitative chemical measurements are conducted in tandem with examinations of microbial activity. This information on selected algae in the laboratory will assess the most appropriate methods for tracking microbial activity. The aims of the project are: 1) To determine the changes in phytoplankton as it is degraded in the water column in the laboratory under both oxic and anoxic enivronments. 2) To explore the relationship between microbial metabolism and production and the transformation of algal carbon during decomposition. 3) To compare the rates of alteration in classes of phytodetritus organic matter with microbial activities for the construction of lability indices for both individual and specific classes of organic matter.
