Spatial Organization of Microbial Biofilm Communities.

The application of advanced microscopy and molecular and electrochemical high-resolution methods has provided insights into the structural organization and function of biofilm communities. It appears that cellular properties such as growth differentiation, chemotaxis, and cell-to-cell signaling enable biofilm communities to organize structurally in response to the external conditions and the activities of the different biofilm members. Thereby resource utilization becomes optimized, and processes which require syntrophic relationships or special micro-environments become facilitated.
