Mycobacterium tuberculosis forms drug tolerant biofilms when cultured in certain conditions. Here we describe methods for culturing M. tuberculosis biofilms and determining the frequency of drug tolerant persisters. These protocols will be useful for further studies into the mechanisms of drug tolerance in M. tuberculosis.

Antimicrobial-induced changes to Pseudomonas aeruginosa biofilm architecture differ among clinical isolates cultured from patients with cystic fibrosis and chronic pulmonary infection. Following confocal microscopy, COMSTAT software can be utilized to quantify variations in biofilm architecture (e.g., surface area, thickness, biomass) for individual isolates to assess the efficacy of anti-infective agents.

This protocol delivers a modular, BSL-2 workflow combining crystal-violet biomass assays, time-lapse phase-contrast kinetics, confocal 3-D/matrix mapping, SEM ultrastructure, and an in vivo hamster infection module to cultivate, quantify, characterize and investigate Leptospira biofilm functional role, enabling standardized evaluation of mutants and anti-biofilm interventions across laboratories.
FAQs
The spatial arrangement of cells, matrix, clusters, channels, and layered regions creates zones that differ in nutrient, oxygen, and waste levels. These microscale gradients mean that microorganisms in one part of a biofilm may experience conditions unlike those elsewhere. Examining this organization helps explain how structure influences growth, interactions, and responses to the surrounding environment.
The extracellular polymeric substance matrix surrounds microbial cells and helps establish the physical organization of the community. Its presence supports the development of clusters, channels, and layers rather than a uniformly distributed population. In bioengineering, considering this matrix is important because the resulting structure affects transport through the biofilm and the community’s functional behavior.
These structural features organize microorganisms into distinct spatial environments. They influence how nutrients and oxygen reach cells, how waste accumulates, and how neighboring microorganisms interact. Because architecture links microscale arrangement with transport and resilience, identifying these features can clarify why a community functions differently from a dispersed population under the same broader environmental conditions.
Structural measurements characterize the three-dimensional organization of cells and their surrounding matrix. Researchers can then relate microscale features to transport, resilience, and community function rather than examining growth only as a bulk property. In bioengineering, these measurements provide evidence for evaluating how biofilms behave within designed systems and how their organization may support or hinder performance.
Biofilm architecture is relevant when designing engineered surfaces, bioreactors, and treatment systems because spatial organization affects microbial growth, interactions, transport, and environmental response. Structural analysis can reveal whether a system promotes a useful community arrangement or supports an undesirable one. This makes architecture a useful consideration in both developing biofilm-based technologies and managing harmful biofilms.
Analysis identifies how microbial organization, matrix distribution, clusters, channels, and layers relate to local conditions and community resilience. That information can guide strategies aimed at changing or limiting structures that support persistent growth. The approach is especially relevant to bioengineering, where control decisions must account for the three-dimensional organization of the microbial community rather than cells alone.
