Bacteria undergo significant changes during adherence to surfaces and biofilm development. Cell-to-cell signalling molecules are known to be involved in these phenotypic adaptations to the sessile mode of life. We demonstrated previously that indole can act as an extracellular signal to regulate biofilm formation in E. coli. To identify proteins over- or under-expressed in response to E. coli biofilm formation and indole signalling, we compared the proteomes of the E. coli S17-1 wild-type and… Expand
Escherichia coli heat-shock proteins IbpA and IbpB affect biofilm formation by influencing the level of extracellular indole.
TLDR
It is demonstrated that the formation of biofilm by the ibpAB mutant was delayed due to the increase in the extracellular concentration of indole, which is known to play the role of a signal molecule, inhibiting biofilm growth. Expand
Biofilm-induced modifications in the proteome of Pseudomonas aeruginosa planktonic cells.
TLDR
It is demonstrated that planktonic organisms are able to detect the presence of a biofilm in their close environment and to modify their gene expression in consequence. Expand
Proteomic regulation during Legionella pneumophila biofilm development: decrease of virulence factors and enhancement of response to oxidative stress.
TLDR
The influence of the biofilm mode of growth on the proteome of L. pneumophila is reported for the first time and hypothetical proteins, that appear to be unique to the Legionella genus, were over-expressed by sessile bacteria. Expand
Released products of pathogenic bacteria stimulate biofilm formation by Escherichia coli K-12 strains
TLDR
Proteinase K significantly reduced the stimulatory effects of all supernatants, indicating a prominent role of protein/peptide factor(s) in biofilm promotion, and the biofilm-modulating effects of sterile stationary-phase culture media of a biofilm non-producing strain of E. coli were compared.

Biofilm Formation-Gene Expression Relay System in Escherichia coli: Modulation of σS-Dependent Gene Expression by the CsgD Regulatory Protein via σS Protein Stabilization
TLDR
Evidence is presented that the CsgD protein, a transcription regulator involved in biofilm formation in Escherichia coli, modulates the expression of the rpoS (sigma(S)) regulon, which could positively impact important biological processes, including host colonization or response to environmental stresses. Expand
Quantitative protein expression and cell surface characteristics of Escherichia coli MG1655 biofilms
TLDR
It is hypothesized that cells grown as a BIO are still energetically viable potentially using amino acids as an indirect carbon backbone source into the TCA cycle. Expand
Production of Indole from l-Tryptophan and Effects of These Compounds on Biofilm Formation by Fusobacterium nucleatum ATCC 25586
TLDR
Exogenous tryptophan and indole were suggested to increase F. nucleatum biofilm formation and the biofilm supernatant concentration of indole increased dose dependently with increasing tryptophile concentrations. Expand
Indole Acts as an Extracellular Cue Regulating Gene Expression in Vibrio cholerae
TLDR
It was shown that indole activating genes involved in vibrio polysaccharide (VPS) production, which is essential for V. cholerae biofilm formation, influences the expression of many other genes, including those involved in motility, protozoan grazing resistance, iron utilization, and ion transport. Expand
Analysis of uropathogenic Escherichia coli biofilm formation under different growth conditions.
TLDR
Analysis of the biofilm formation of 115 clinical uropathogenic Escherichia coli strains under different growth conditions suggests that most of the bacterial cells prefer to live in a biofilm community under the difficult environmental conditions and suggests that mechanisms ofBiofilm formation can be correlated with other bacterial properties.

Indole Affects Biofilm Formation in Bacteria
TLDR
The signaling role and molecular mechanism of indole on bacterial biofilm formation are reviewed, as well as its relation to bacterial living adaptivity. Expand

Indole can act as an extracellular signal to regulate biofilm formation of Escherichia coli and other indole-producing bacteria.
TLDR
Indole, produced by the action of tryptophanase, is involved in polystyrene colonization by several indole-producing bacterial species and may act as a signalling molecule to regulate the expression of adhesion and biofilm-promoting factors. Expand
Global gene expression in Escherichia coli biofilms
TLDR
Genes encoding proteins involved in adhesion and autoaggregation and several novel gene clusters were induced upon the transition to biofilm growth, and these included genes expressed under oxygen‐limiting conditions, genes encoding (putative) transport proteins, putative oxidoreductases and genes associated with enhanced heavy metal resistance. Expand
Abiotic Surface Sensing and Biofilm-Dependent Regulation of Gene Expression in Escherichia coli
TLDR
It is shown that bacteria within biofilms encounter higher-osmolarity conditions, greater oxygen limitation, and higher cell density than in the liquid phase, which seems to result from changes in multiple environmental physicochemical conditions. Expand
Characterization of Phenotypic Changes inPseudomonas putida in Response to Surface-Associated Growth
TLDR
The results presented here demonstrate that P. putida undergoes a global change in gene expression following initial attachment to a surface, and quorum sensing may play a role in the initial attachment process, but other sensory processes must also be involved in these phenotypic changes. Expand
Pseudomonas aeruginosa Displays Multiple Phenotypes during Development as a Biofilm
TLDR
The results demonstrate that P. aeruginosa displays multiple phenotypes during biofilm development and that knowledge of stage-specific physiology may be important in detecting and controlling biofilm growth. Expand
Global impact of mature biofilm lifestyle on Escherichia coli K‐12 gene expression
TLDR
It is shown that the expression of stress envelope response genes, such as the psp operon or elements of the cpx and rpoE pathways, is a general feature of E. coli mature biofilms. Expand
Biofilm formation of Pseudomonas putida IsoF: the role of quorum sensing as assessed by proteomics.
TLDR
Comparing proteome analyses of the P. putida wild type IsoF and the QS-deficient mutant F117 grown either in planktonic cultures or in 60 h old mature biofilms provide strong evidence that the set ofQS-regulated proteins overlaps substantially with the setof proteins differentially expressed in sessile cells. Expand
The stringent response genes relA and spoT are important for Escherichia coil biofilms under slow-growth conditions.
TLDR
Results suggest that both stringent response genes relA and spoT are important in nutrient-limited biofilm formation in Escherichia coli DS291 mutants. Expand
A proteomic study of Escherichia coli O157:H7 NCTC 12900 cultivated in biofilm or in planktonic growth mode.
TLDR
The results of this study showed that E. coli O157:H7 modified the expression of several proteins involved in biofilm growth mode, showing clear differences between protein patterns of sessile and planktonic cells. Expand
Proteomic Analysis Reveals Differential Protein Expression by Bacillus cereus during Biofilm Formation
TLDR
Interestingly, increased levels of YhbH, a member of the sigma 54 modulation protein family which is strongly induced in response to environmental stresses and energy depletion via both σB and σH, could be observed within 2 h in both attached cells and planktonic cultures growing in the presence of glass wool, indicating that this protein plays an important role in regulation of the biofilm phenotype.
