data_set_deAnna_et_al_2020_chemotaxis_dispersion

Data set associated to the publication "Chemotaxis under flow disorder shapes microbial dispersion in porous media". It includes the following:

i) images of bacterial distribution in a microfluidics porous medium replica while displaced by a continuously injected front of a solute triggering microbial chemotaxis towards positive gradients (attractant).

ii) images of bacterial distribution in a microfluidics porous medium replica while displaced by a continuously injected front of a solute triggering microbial chemotaxis towards negative gradients (repellent).

iii) images of a continuously injected front of fluorescent tracer.

iv) images of a chemotaxis assay to characterize positive/negative chemotaxis towards/from a chemoattractant/repellent: no flow conditions, steady and homogeneous chemical gradient.
