Adjustment in tumbling rates improves bacterial chemotaxis on obstacle-laden terrains [Biophysics and Computational Biology]

The mechanisms of bacterial chemotaxis have been extensively studied for several decades, but how the physical environment influences the collective migration of bacterial cells remains less understood. Previous models of bacterial chemotaxis have suggested that the movement of migrating bacteria across obstacle-laden terrains may be slower compared with terrains without...
