Key Points

This study aims to understand the rheological behavior of Escherichia coli suspensions and the impact of bacterial morphologies and motility.
Conducted experiments with motile and non-motile strains of Escherichia coli.
Analyzed rheological properties and flow characteristics of suspensions.
Evaluated the effects of flagella presence on suspension behavior.
Identified distinct rheological behaviors linked to different bacterial morphologies.
Demonstrated that motility significantly influences the flow properties of bacterial suspensions.
Found that de-flagellated strains showed reduced rheological complexity compared to motile strains.

Implication

Examines rheological behavior of Escherichia coli suspensions, indicating complex interactions with fluids.

Abstract

Motile bacteria can interact with surrounding fluids, creating complex rheological behavior of suspensions. Yet such studies with paralyzed flagella or de-flagellated bacteria are limited, leaving the separate roles of motility,...
