Raw concentrations of individual PLFA compounds from Massachusetts from 2012-2015.

<p>We conducted two sets of&nbsp;13C label addition experiments. In one set, we evaluated how nutrient fertilization affected bacterial utilization of BMA carbon over a growing season. In the other set, we used&nbsp;13C-labelled&nbsp;S.&nbsp;alterniflora&nbsp;to assess bacterial incorporation of recently-produced macrophyte detritus.&nbsp;Data presented are raw concentrations individual PLFA compounds (ng g-1&nbsp;dry sediment) measured in surface sediments.</p>本研究开展了两组13C标记添加实验。其中一组实验旨在评估在一个生长季内，养分施肥如何影响细菌对底栖微藻（Benthic Microalgae, BMA）碳源的利用情况；另一组实验则使用13C标记的互花米草（Spartina alterniflora），以探究细菌对新近产生的大型水生植物碎屑的同化过程。本次展示的数据为表层沉积物中测得的单个磷脂脂肪酸（Phospholipid Fatty Acid, PLFA）化合物的原始浓度，单位为纳克每克干沉积物（ng g⁻¹ dry sediment）。
