Hydrolytic enzyme activities during CDOM monoculture experiments with Skeletonema, Leptocylindrus, and Phaeocystis

<p>This dataset is from a laboratory experiment. Four phytoplankton cultures and their associated bacterial communities were incubated in replicate roller bottles (1.9 L) over 3-6 weeks under laboratory conditions. Bacterial dynamics in the culture bottles were measured and correlated with geochemical parameters to determine the role of bacterial activities on the formation of CDOM in the cultures (Kinsey et al., 2018, see below).</p>

<p>The data include fluorescence and&nbsp;bacterial enzyme activity during CDOM monoculture experiments. The phytoplankton cultures were Skeletonema sp., Leptocylindrus sp., and Phaeocystis sp.&nbsp;Growth stages were initial, exponential, stationary, and degradation.&nbsp;</p>

本数据集源自一项实验室实验。研究将4种浮游植物培养物及其伴生细菌群落置于重复设置的1.9 L滚瓶中，在实验室环境下培养3至6周。对培养瓶内的细菌动态进行测定，并与地球化学参数开展关联分析，以明确细菌活动对该培养体系中有色溶解有机物（CDOM，Chromophoric Dissolved Organic Matter）形成的作用（Kinsey等，2018，详见下文）。

数据集包含CDOM单培养实验过程中的荧光信号与细菌酶活性数据。所用浮游植物培养物涵盖骨条藻属（Skeletonema sp.）、细柱藻属（Leptocylindrus sp.）与棕囊藻属（Phaeocystis sp.）。实验设置的生长阶段包括起始期、指数生长期、稳定期及降解期。
