Study of Internal Micromechanical Properties of Pseudomonas Aeruginosa Biofilms by Brillouin Scattering (CAT#: STEM-ST-0143-YJL)

Introduction

Biofilms are developed when extracellular polymeric substances (EPS) are secreted from adherent bacterial cells to form a matrix that encloses bacterial cells. They readily adhere to biological or non-biological surfaces, are highly dynamic and heterogeneous, yet have a distinct lifecycle. The EPS accounts for the largest part of the dry mass of biofilms (up to 90%)10 and is responsible for the formation and maintenance of biofilms and their three-dimensional architecture. The matrix is a cross-linked network of polymers and has presumably multiple roles in the life of biofilms.

P. aeruginosa is an opportunistic bacterial pathogen commonly used as a model organism for biofilm formation.
