Pseudomonas aeruginosa
. However, it has become evident that this is not how all biofilms develop, especially in vivo, in clinical and industrial settings, and in the environment, where biofilms often are observed as non-surface-attached aggregates. In this Review, we describe the origin of the current five-step biofilm development model and why it fails to capture many aspects of bacterial biofilm physiology. We aim to present a simplistic developmental model for biofilm formation that is flexible enough to include all the diverse scenarios and microenvironments where biofilms are formed. With this new expanded, inclusive model, we hereby introduce a common platform for developing an understanding of biofilms and anti-biofilm strategies that can be tailored to the microenvironment under investigation.
In this Review, Bjarnsholt and colleagues propose a revised conceptual model of the biofilm life cycle that encompasses the three major steps of biofilm formation — aggregation, growth and disaggregation — independently of surfaces, and initiation from single-cell planktonic bacteria, and thus represents a broader range of biofilm systems. |
