Bacteria & Biofilms


Bacteria are able to colonize any surfaces and produce extracellular matrix in which they may embed and survive in many different environments. This extracellular matrix is mostly composed of water, polysaccharides, proteins and DNA and it confers to the colony a true cohesion and properties of solid and soft matter. Biofilms are ubiquitous and may play positive or negative role to their environment depending on the settings, context and biofilms nature. For that reasons, most research studies on biofilms have been conducted at the level of applied sciences since the last fifteen years and large part of biofilm biophysics remain to be discovered. In the laboratory, we are interested in different biofilm properties.
