Dissecting the physics of bacterial biofilms with agent-based simulations.

Area of Science:

• Microbiology
• Biophysics
• Computational Biology

Background:

• Biofilms are resilient, surface-attached bacterial communities within extracellular matrices (ECMs).
• The ECM's complex biopolymer network provides structural integrity and resilience.
• Advanced live imaging reveals cellular organization dynamics during biofilm formation.

Purpose of the Study:

• To review agent-based models (ABMs) as a framework for simulating bacterial biofilm development.
• To detail the components and assumptions of ABMs in biofilm research.
• To highlight ABM applications in understanding biofilm physical mechanisms.

Main Methods:

• Agent-based modeling (ABM) framework.
• Simulation of bacterial colony and biofilm development.
• Analysis of orientational ordering in *Vibrio cholerae* biofilms.

Main Results:

• ABMs provide mechanistic insights into biofilm organization.
• Modeling reveals physical drivers of cellular arrangement within biofilms.
• Specific ABM applications demonstrate utility in studying biofilm structure.

Conclusions:

• ABMs are powerful tools for simulating and understanding biofilm development.
• Further application of ABMs will enhance knowledge of biofilm formation and behavior.
• ABMs can predict emergent properties of bacterial communities.
