Dataset for: Bacterial motility enhances adhesion to oil droplets

The dataset consists of: a. z-stack images (.tiff) of 20 um and 50 um drop diameters at different time intervals for motile bacteria; b. z-stack images (.tiff) of 20 um and 50 um drop diameters at different time intervals for non-motile bacteria; c. z-stack images (.tiff) 20 um and 50 um drop diameters at different surfactant concentrations for motile bacteria; d. z-stack images (.tiff) 20 um and 50 um drop diameters at different surfactant concentrations for non-motile bacteria The data analyzed consists of: a. number of cell and cells normalized with drop surface area as a function of time; b. cell areal density as a function of surfactant concentration; c. interfacial tension as a function of surfactant concentration; c. cell areal density as a function of interfacial tension. This project investigated the effect of bacteria motility and surfactant concentration on the initial adhesion of Marinobacter hydrocarbonoclasticus and Halomonas titnicae at the interface of hexadecane droplets suspended in seawater. This dataset supports the publication of Dewangan, Narendra K. and Conrad, Jacinta C. “Bacterial motility enhances adhesion to oil droplets.” Soft Matter (2020). https://doi.org/10.1039/D0SM00944J本数据集包含以下内容：a. 不同时间间隔下，运动型细菌（motile bacteria）在直径为20 μm与50 μm的液滴上的Z堆叠图像（z-stack，.tiff格式）；b. 不同时间间隔下，非运动型细菌（non-motile bacteria）在直径为20 μm与50 μm的液滴上的Z堆叠图像（z-stack，.tiff格式）；c. 不同表面活性剂浓度（surfactant concentration）下，运动型细菌在直径为20 μm与50 μm的液滴上的Z堆叠图像（z-stack，.tiff格式）；d. 不同表面活性剂浓度下，非运动型细菌在直径为20 μm与50 μm的液滴上的Z堆叠图像（z-stack，.tiff格式）。 分析所得数据集包含以下内容：a. 随时间变化的细菌细胞总数及经液滴表面积归一化后的细胞数；b. 随表面活性剂浓度变化的细菌面密度；c. 随表面活性剂浓度变化的界面张力；c. 随界面张力变化的细菌面密度。 本研究探究了细菌运动性与表面活性剂浓度对悬浮于海水中的十六烷液滴界面处解烃海杆菌（Marinobacter hydrocarbonoclasticus）与泰坦盐单胞菌（Halomonas titnicae）的初始附着行为的影响。 本数据集支撑了Dewangan、Narendra K.与Conrad、Jacinta C.发表于《软物质（Soft Matter）》2020年的论文《细菌运动性增强其对油滴的附着》（原文标题："Bacterial motility enhances adhesion to oil droplets"），DOI: 10.1039/D0SM00944J。
