Interplay between environmental yielding and dynamic forcing regulates bacterial growth
Anna M. Hancock,

Abstract:Many bacterial habitats—ranging from gels and tissues in the body to cell-secreted exopolysaccharides in biofilms—are rheologically complex, undergo dynamic external forcing, and have unevenly-distributed nutrients. How do these features jointly influence how the resident cells grow and proliferate? Here, we address this question by studying the growth ofEscherichia colidispersed in granular hydrogel matrices with defined and highly-tunable structural and rheological properties, under different amounts of exte… Show more
