Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Data supporting Inhibition of the Growth of Harmful Algal Bloom-forming Freshwater Cyanobacteria by Clay
    (2022-03-14) Yang, Judy Q; Tomaska, Katherine R; Wei, Guanju; tomas098@umn.edu; Tomaska, Katherine R; Yang Research Group: Environmental Transport Lab
    This dataset contains cell density measurements and confocal images of Microcystis Aeruginosa. The raw data from hand counting cells under a microscope with a hemocytometer is included, as well as the calculated cell density based on the hemocytometer measurements. The bacteria cells were grown in one of three growth conditions. Each growth condition was simulated in three different flasks. For each date, the cell densities of identical growth conditions were averaged. Cell densities for each date and growth condition were subsequently plotted with error bars to determine any trends. Additionally, data on the environmental conditions of cell growth are included on dates when the measurements were taken. The physical interactions between cyanobacteria and clay particles were visualized using a confocal laser scanning microscope (Nikon C2 plus). Each image is around 2048 by 2048 pixels at a resolution of 0.08 um/pixel. We used a 20X objective magnification. A sequence of images was taken at 10-second intervals for 5 minutes. The laser used for excitation has a wavelength of 488 nm (FITC) and the emission wavelength is 525 nm.

    Data supporting Motility directs Pseudomonas aeruginosa towards surfaces and enhances biofilm formation
    (2024-08-08) Wei, Guanju; Yang, Judy Q; judyyang@umn.edu; Yang, Judy Q; University of Minnesota, Saint Anthony Falls Laboratory
    This dataset contains all the angles and trajectories for both motile and non-motile Pseudomonas aeruginosa cells. In the manuscript, we demonstrated that the cell motility can enhance biofilm formation and utilized the orientation angle and trajectory data to support this conclusion.

    Experimental data of biofilm development experiments under fluctuating flow conditions taken and processed at SAFL in 2022
    (2023-05-04) Wei, Guanju; Yang, Judy Q; judyyang@umn.edu; Yang, Judy; University of Minnesota, Saint Anthony Falls Laboratory, Environmental Transport Lab
    This dataset consists of the Matlab codes, experimental data, and raw images of the biofilm development experiments under fluctuating flow conditions. They are all collected in the Saint Anthony Falls Laboratory at the University of Minnesota. The codes are used for processing the raw images to calculate the biofilm thickness and biofilm area coverage. The experimental data file contains the data after processing. The image file contains the raw images collected during the experiments using the Nikon confocal microscope.
