Diversity generally protects communities from unstable environmental conditions. This principle, known as the "insurance hypothesis," has been tested in many different ecosystems. Here we show that the opportunistic pathogen Pseudomonas aeruginosa undergoes extensive genetic diversification during short-term growth in biofilm communities. The induced genetic changes are produced by a recA-dependent mechanism and affect multiple traits, including the behavior of the bacteria in biofilms. Some… Expand
Genetic variation in biofilms and the insurance effects of diversity.
TLDR
Evidence that P. aeruginosa undergoes extensive genetic diversification during growth in biofilm communities is presented and it is shown that biofilms that had genetically diversified were better able to withstand an applied physiological stress as compared to biofilm that were unable to diversify. Expand
Biofilm diversity as a test of the insurance hypothesis.
TLDR
The report is important in that it represents one of very few attempts to examine biofilm communities in the light of ecological theory, but the authors’ conclusion that diversification in a biofilm is somehow a programmed response to that lifestyle is questioned. Expand
Endogenous oxidative stress produces diversity and adaptability in biofilm communities
TLDR
It is hypothesized that the mutations produced could promote the adaptation of biofilm communities to changing conditions in addition to generating diversity, and it was found that the oxidative stress-break repair mechanism increased the emergence of antibiotic-resistant bacteria. Expand
Rapid evolution of culture-impaired bacteria during adaptation to biofilm growth.
TLDR
It is shown that culture-impaired variants of Pseudomonas aeruginosa arise rapidly and become abundant in laboratory biofilms, caused by mutations that alter the outer-membrane lipopolysaccharide structure. Expand
Biofilm: A Hotspot for Emerging Bacterial Genotypes.
TLDR
This review summarizes the present knowledge within this important area of research on bacterial evolution in biofilms and indicates that there is growing evidence that the biofilm lifestyle may be more mutagenic than planktonic growth. Expand
Ecological succession in long-term experimentally evolved biofilms produces synergistic communities
TLDR
The parallel evolution of synergistic communities derived from a clone of Burkholderia cenocepacia during ∼1500 generations of biofilm selection is described, enabled by a new experimental method that selects for daily cycles of colonization, biofilm assembly and dispersal. Expand
Phenotypic Variation during Biofilm Formation: Implications for Anti-Biofilm Therapeutic Design
TLDR
It is concluded that a combinatorial approach must be taken to provide complete protection against biofilm forming bacterial and their resulting diseases. Expand
Dynamics of development and dispersal in sessile microbial communities: examples from Pseudomonas aeruginosa and Pseudomonas putida model biofilms.
TLDR
The available evidence suggest that the biofilm forming organisms do not possess comprehensive genetic programs for biofilm development, but instead the bacteria appear to have evolved a number of different mechanisms to optimize surface colonization, of which they express a subset in response to the prevailing environmental conditions. Expand
Toxic metal resistance in biofilms: diversity of microbial responses and their evolution.
TLDR
This review describes how metals impact biofilm formation and resistance, and how biofilms can help cells resist toxic metals and discuss how the high density of the cells may promote horizontal gene transfer processes, resulting in the acquisition of new features. Expand
Phenotypic switching: an opportunity to bacteria thrive
TLDR
The impact of generating population-level diversity on important clinical issues as resistance, virulence and persistence is discussed, highlighting that even though the growing interest and relevance of this phenomenon and its impact on bacterial ecology, the evolutionary origins and adaptive significance remain poorly understood.

Initiation of biofilm formation by Pseudomonas aeruginosa 57RP correlates with emergence of hyperpiliated and highly adherent phenotypic variants deficient in swimming, swarming, and twitching motilities.
TLDR
This report describes the characterization of phenotypic variants forming small, rough colonies that spontaneously emerged when P. aeruginosa 57RP was cultivated as a biofilm or in static liquid cultures, and concludes that these S variants resulted from phase variation and were selectively enriched when.

TLDR
Bacteria benefit from multicellular cooperation by using cellular division of labor, accessing resources that cannot effectively be utilized by single cells, collectively defending against antagonists, and optimizing population survival by differentiating into distinct cell types. Expand
Quorum-sensing signals indicate that cystic fibrosis lungs are infected with bacterial biofilms
TLDR
The hypothesis that P. aeruginosa might exist as biofilms—structured communities of bacteria encased in a self-produced polymeric matrix—in the cystic fibrosis lung is supported by microscopy of cystic Fibrosis sputum, which shows that the bacterium are in biofilm-like structures. Expand

TLDR
The role played by the las and rhl QS systems during the early stages of static biofilm formation when cells are adhering to a surface and forming microcolonies is investigated and its implications for the design of biofilm prevention and eradication strategies are investigated. Expand

TLDR
Microarray technology was used to study the effects of subinhibitory concentrations of a β-lactam antibiotic, imipenem, on gene expression in biofilm populations, and it was found that genes coding for alginate biosynthesis were induced by exposure to imipanem. Expand
