Description

Content:

This dataset includes images of 10 different biofilm growth experiments to observe intermittent flow paths in a microfluidic channel. All images taken by optical microscopy per five minutes. The experiments took in avarage 4-5 days. The published data is the raw images of the experiments. The images names were related to the timestamps as [YYYY_MM_DD_hh-mm-ss].

  • All further referenced files are compressed into the folder Files.tar.gz. After extracting, all files are accessible.

This dataset contains in detail:

  • The captured images of the experiments used for post processing to evaluate the frequency of the intermittent flow paths.

 

  1. E2_images.tar.gz contains the images of the experiment with an average starting nutrient broth velocity of 0,23 mm/s in the narrow channel.
  2. E3_1_images.tar.gz contains the images of the first experiment with an average starting nutrient broth velocity of 0,8 mm/s in the narrow channel.
  3. E3_2_images.tar.gz contains the images of the second experiment with an average starting nutrient broth velocity of 0,8 mm/s in the narrow channel.
  4. E4_1_images.tar.gz contains the images of the first experiment with an average starting nutrient broth velocity of 1,6 mm/s in the narrow channel.
  5. E4_2_images.tar.gz contains the images of the second experiment with an average starting nutrient broth velocity of 1,6 mm/s in the narrow channel.
  6. E5_images.tar.gz contains the images of the experiment with an average starting nutrient broth velocity of 0,8 mm/s in the wide channel.

 

  • The captured images used to qualify the biofilm growth and the occurrence of intermitting flow paths with higher and lower velocities compared to the experiments where intermittency was clearly visible.

 

  1. E1_images.tar.gz contains the images of the experiment with an average starting nutrient broth velocity of 0,114 mm/s in the narrow channel.
  2. E1.2_images.tar.gz contains the images of the experiment with an average starting nutrient broth velocity of 0,114 mm/s in the narrow (repetititon).
  3. E1.3_images.tar.gz contains the images of the experiment with an average starting nutrient broth velocity of 0,114 mm/s with higher nutrient concentration in the narrow channel.
  4. E6_1images.tar.gz contains the images of the first experiment with an average starting nutrient broth velocity of 1,6 mm/s in the wide channel.
  5. E6_2_images.tar.gz contains the images of the second experiment with an average starting nutrient broth velocity of 1,6 mm/s in the wide channel.
  6. E7_images.tar.gz contains the images of the experiment with an average starting nutrient broth velocity of 0,8 mm/s in narrow channel with pore bodies.
