Biofilms in natural and engineered environments are dynamic ecosystems harboring a complex microbial community. Attachment and initial growth are the important first steps for the development of a biofilm on a clean surface. Once established, biofilms undergo maturation. Milferstedt et al. have developed a quantitative tool to track the development of biofilm architecture during initial growth and subsequent maturation. Large scale images (13.3 ร 8.7 mm 2 ) were analyzed over periods of 10 weeks using quantitative texture analysis. The authors present first indicators of developmental succession cycles initiated by sloughing of large amounts of biomass. The evaluation of mixed culture biofilms examined at larger spatial and temporal scales will provide the necessary framework to understand the fundamental relationship between biofilm architecture and function in natural and engineered systems.
