are thought to exist as surface-associated communities in biofilms.Bacterial biofilms are encased within a matrix and attached to a surface.Biofilm formation and development are commonly studied in the laboratory using batch systems such as microtiter plates or flow systems, such as flow-cells. ...
Flow cells are therefore similar to fuel cells in their configuration, but unlike fuel cells, they can be electrically charged and can therefore be used for the storage of energy. A typical cell stack is made up of a series of cells that are electrically connected to adjacent cells via ...
Another biofilm application was shown by Peschke and coworkers for 5-nitrononane-2,8-dione reduction with E. coli biofilms [26]. The cells were cultivated in a meandering channel structure in a PDMS-glass-based microfluidic chip system. They were able to reach a space–time yield of 4.6 g...

Bacterial cells are assumed here to be ideal spheres covered uniformly with springlike receptors. The model describes the specific binding between receptor molecules on the cell and ligands associated with the target surface. Accounting for the processes of attachment, detachment, and growth of ...
213 g for 15 min to remove microbial cells. An equal volume of HPLC-grade methanol (Millipore-Sigma, Catalog no. 34860) was added into the supernatants of each sample, followed by incubation on ice for 30 min, vortexing each sample every 10 min to ensure proper liquid–liquid extraction. ...
3b. The effect is not present for passive particles or non-motile bacteria (V0 ¼ 0). Width of the depletion zone Rd can be estimated from the analysis of linearized equation (5). Let us compare the relaxation rate l¼ À V0 cosðc1Þ=r þ 2oR2 sinð2c1Þ=r2 ...
The device was made of 5 mm thick transparent acrylic glass, with the two cells connected at the bottom. DN25 PPR perforated pipes were laid on the surface for water distribution and collection, and a peristaltic pump controlled the inflow rate. Construction of the hydraulic numerical model for...
We have in mind applications to the study of cells, biofilms and tissues, where one phase is a liquid solution, whereas the other one is assorted biomass. To focus the analysis, we consider a specific model for bacterial biofilm spread [13], [31]: (1)div(vlϕl)=kbcc+Kb(ϕl−...
monitoring using microsensors in flow cells or flat plate reactors (De La Rosa and Yu, 2005; Santegoeds et al., 1998; Sarti et al., 2016), none of them had reported an anaerobic platform that allows H2S characterization in different zones and biofilm depths in order to obtain a 3D ...
