Abstract

The article discusses evidence that extracellular DNA is critical for the initial phase of biofilm development by Staphylococcus epidermidis on polystyrene or glass surfaces under static or hydrodynamic conditions. Results indicate that extracellular DNA is generated in S. epidermidis populations through Atlee-mediated lyses of a subpopulation of the bacteria, and that the extracellular DNA promotes biofilm formation of the remaining population.

Abstract

The extracellular matrix of microbial biofilms has traditionally been viewed as a structural scaffold that retains the resident bacteria in the biofilm. Moreover, a role of the matrix in the tolerance of biofilms to antimicrobials and environmental stressors was recognized early in biofilm research. However, as research progressed it became apparent that the biofilm matrix can also be involved in processes such as bacterial migration, genetic exchange, ion capture and signalling. More recently, evidence has accumulated that the biofilm matrix can also have catalytic functions. Here we review foundational research on this fascinating catalytic role of the biofilm matrix.
