Dataset for: Hydrodynamic attraction of bacteria to gas and liquid interfaces

The motion of bacteria near gas, fluid, and solid interfaces is investigated in the Complex Flow Lab of the Mechanical Engineering department of Purdue University. Experimental data were captured using an inverted microscope and processed to find the individual trajectories of Escherichia coli cells within the imaging domain. Numerical simulations were conducted using the super-computing clusters at Purdue. Using MATLAB software, the numerical results investigated the distribution of bacteria near gas, liquid, and solid surfaces. Both experimental and simulated data were collected in 2018 and 2019 to study the attraction of motile bacteria to liquid and gas interfaces. The dataset contains the data needed to re-create figures in the accompanying manuscript, as well as trajectories and distributions of E. coli 437. This dataset supports the publication: Ahmadzadegan, A., Wang, S., Vlachos, P. P., & Ardekani, A. M. (2019). Hydrodynamic attraction of bacteria to gas and liquid interfaces.

本数据集源自普渡大学（Purdue University）机械工程系复杂流动实验室的研究工作，聚焦于细菌在气、液、固界面附近的运动行为。研究团队采用倒置显微镜（inverted microscope）采集实验数据，并通过图像处理提取成像视野内大肠杆菌（Escherichia coli）细胞的个体运动轨迹。本研究依托普渡大学超级计算集群完成数值模拟，并借助MATLAB软件对模拟结果进行分析，以探明细菌在气、液、固界面附近的分布特征。实验与模拟数据均采集于2018至2019年，用于探究具运动能力的细菌对气液界面的水动力吸引行为。本数据集包含复现随附手稿中所有图表所需的数据，以及大肠杆菌437的运动轨迹与分布数据。本数据集支持以下已发表成果：Ahmadzadegan, A., Wang, S., Vlachos, P.
