Experimental4
- This information can be very helpful when developing experimental approaches to evaluate biofilm control strategies. (cdc.gov)
- The experimental system for growing the biofilm is a flow cell (Figure 2). (montana.edu)
- Additionally, the experimental approach could be used to discover other, potentially medically important biofilm-inhibiting bacterial, said Shank. (sciencedaily.com)
- According to the experimental results, the biofilm response changes under pressure, with significant differences noted in morphological characteristics, the extracellular polymeric substances (EPS) spatial structure, bacterial diversity, and functional abundance potential. (bvsalud.org)
Dispersal2
- This can contribute to biofilm dispersal, and provides a mechanism for the release of extracellular DNA (eDNA) within biofilms. (southampton.ac.uk)
- Nitric oxide-mediated regulation of biofilm dispersal. (southampton.ac.uk)
Biology2
- The first such conference ever held at the Met, the Art, Biology, and Conservation 2002 meeting provided an opportunity for close to 40 scientists and conservators to present their latest research on the interactions of microbes and art, and to offer approaches to counter the effects of biodeterioration. (metmuseum.org)
- A web site with conference details and registration information is available on line at http://nature.berkeley.edu/P2000 or contact Steven Lindow, University of California, Department of Plant and Microbial Biology, 111 Koshland Hall, Berkeley, CA 94720-3102. (bio.net)
Fungal1
- Biofilms were stained with SYTO 9 ( green , live bacteria), FUN-1 (intracellular red , live fungal cells), calcofluor white ( blue , fungal cell wall). (asmblog.org)
Chapter2
- Chapter 1 provides a balanced comparison of static and continuous flow methods for growing biofilms that should be beneficial for researchers investigating biofilm development or dispersion, and for applied studies evaluating new treatment strategies for biofilm prevention and control. (cdc.gov)
- Chapter 1 also provides a helpful but brief discussion of the use of "omic" approaches (i.e., genomic, metagenomic, transcriptomic, and proteomic) in the study and characterization of biofilms. (cdc.gov)
Organisms2
- In biofilms, symbionts play major roles in the relationship among organisms by the production of bioactive molecules involved in quorum sensing signaling. (intechopen.com)
- Promising strains are isolated and the interaction of model organisms is investigated to understand the specific metabolic interplay between the autotrophic and heterotrophic partners. (dsmz.de)

Chlorine3
- This is consistent with incomplete penetration of chlorine into the biofilm. (montana.edu)
- Residual chlorine and biofilm coexistence is inevitable in drinking water transmission and distribution networks. (bvsalud.org)
- Understanding the microbial response and its mediated effects on disinfection byproducts under different categories of residual chlorine stress is essential to ensure water safety. (bvsalud.org)
Compounds3
- My research group aims to understand how biofilms develop and disperse and how they respond to environmental stresses including therapeutic compounds. (southampton.ac.uk)
- Approximately 0.05 GtC yr −1 of organic carbon is estimated to be produced through microbial interactions and oxidation of organic compounds within hydrothermal plumes. (nature.com)
- Cell detachment from pyrite results in microbial "footprints" which, based on lectin binding assays, consist of mannose, glucose and fucose containing compounds. (ufz.de)
Study3
- How do scientists study biofilms? (harvard.edu)
- Because of its unusual position in between two types of host rock, Tjuv-Ante's Cave represents a unique environment in which to study differences in microbe-rock interactions and speleothem genesis between the granite and dolerite host rock. (usf.edu)
- The study of biofilms has emerged over the last three decades in various disciplines such as biotechnology, bioengineering or infectious disease research, leading to rapid progress, but also fragmentation and duplication of effort. (sciencedaily.com)
