CWC: Bacterial diversity data supporting experimental marsh sediment microbial community degradation of S. alterniflora-derived dissolved organic matter

Microbial degradation of dissolved organic matter (DOM) in estuarine systems is important to geochemical processes and microbial community function. This dataset includes the results of a laboratory experiment in which batch microcosms of marsh sediments and seawater were enriched with DOM leachate made with marsh grass, Spartina alterniflora. DOM biodegradation was evaluated over a one-month period using fluorescence spectroscopy (R1.x139.143:0022). These data include the results of DNA extracted from batch experiment sediments after one month, followed by tag 454 pyrosequencing of the V1-V3 region of the bacterial 16S rRNA gene.河口系统中溶解有机质（Dissolved Organic Matter, DOM）的微生物降解，对于地球化学过程与微生物群落功能均具有重要意义。本数据集涵盖一项室内受控实验的结果：该实验以互花米草（Spartina alterniflora）制备的DOM浸出液，对批量微宇宙体系中的潮滩沉积物与海水进行富集处理。研究在为期1个月的周期内，通过荧光光谱法（R1.x139.143:0022）对DOM的生物降解过程进行评估。本数据集同时包含实验运行1个月后，从批量实验沉积物中提取的DNA的检测结果，以及针对细菌16S核糖体RNA基因V1-V3可变区开展的标签化454焦磷酸测序结果。
