...Sweta Anantharaman; Danielle Guercio; Alicia G. Mendoza; Jason M. Withorn; Elizabeth M. Boon Biofilm-based infections pose a serious threat to public health. Biofilms are surface-attached communities of microorganisms, most commonly bacteria and yeast, residing in an extracellular polymeric...

... regulated through transcriptional or post-transcriptional mechanisms or epigenetically by phase variation. Autoaggregation can contribute to bacterial adherence, biofilm formation or other higher-level functions. However, autoaggregation is only required for these phenotypes in some bacteria. Thus...

... on behalf of the Biochemical Society 2018 biofilm chemostat consortia emergent property overflow metabolism resource allocation Scarcity of resources, such as anabolic and catabolic nutrients, can influence the elemental and macromolecular composition of microorganisms [ 5 – 9...

...Fiona Whelan; Jennifer R. Potts Staphylococcus aureus and Staphylococcus epidermidis are an important cause of medical device-related infections that are difficult to treat with antibiotics. Biofilms, in which bacteria are embedded in a bacterially-produced exopolymeric matrix, form on the surface...

...Sabrina Fröls Biofilms or multicellular structures become accepted as the dominant microbial lifestyle in Nature, but in the past they were only studied extensively in bacteria. Investigations on archaeal monospecies cultures have shown that many archaeal species are able to adhere on biotic...

...Carla L. Brown; Karen Smith; Laura McCaughey; Daniel Walker The emergence of pan-resistant strains of Gram-negative pathogens and the ability of many bacteria to form multidrug-resistant biofilms during chronic infection poses the grave threat of bacterial infections that are truly untreatable...

... in biofilms on electrodes. In the present paper, we review the effects of anode potentials on electron-transfer properties of such biofilms, and report on the effect that electrochemical cell configuration may have on performance. 1 To whom correspondence should be addressed (email donal.leech...

...Haluk Beyenal; Jerome T. Babauta The chemical and electrochemical gradients in biofilms play a critical role in electron-transfer processes between cells and a solid electron acceptor. Most of the time, electron-transfer processes have been investigated in the bulk phase, for a biofilm electrode...

...Pablo Sebastián Bonanni; Germán David Schrott; Juan Pablo Busalmen The mechanism of electron transport in Geobacter sulfurreducens biofilms is a topic under intense study and debate. Although some proteins were found to be essential for current production, the specific role that each one plays...

... beneficial functions including conferring stability to biofilms, regulating development or imparting virulence. In the present review, we consider what makes amyloid fibrils so suitable for these roles and discuss recent developments in the study of bacterial amyloids, in particular the chaplins from...

... © The Authors Journal compilation © 2011 Biochemical Society 2011 An alternative argument to explain the shift to aerobic lifestyle of the meningococcus runs as follows. In N. gonorrhoeae biofilms, up-regulation of aniA and norB is observed [ 31 ]. Biofilms contain a high population...

.... Interestingly, we also found that physiologically relevant concentrations of PLUNC-inhibited Pseudomonas aeruginosa biofilm formation in vitro without acting directly as a bactericide. This finding suggests that PLUNC protein may inhibit biofilm formation by airway pathogens, perhaps through its dispersant...

... of bacterial communities in the plant biofilms was analysed by taking samples at four different heights in the system. TGGE profiles of PCR-amplified sequences of the 16 S rRNA gene (V3-hypervariable region) showed significant variations of the bacterial diversity, mainly depending on the concentration of O 2...
