Biofilters

Also known as biological filters are devices that remove a wide range of polluting compounds from a stream of fluid (air or water) through a biological process. How do Biofilters work? The air is drawn near the center of emanation and usually led to a conditioning chamber.  In the chamber the air is saturated with moisture and then guided to a fixed bed of biomass.  The pollutants are absorbed to the biofilm of biomass formed over the fill and subsequently are digested by microorganisms.  In our research group of bacteria motility we are…

More About E. Faecalis: The Main Character Of Our Research Project

Enterococcus faecalis (before 1984, E. faecalis was known asStreptococcus faecalis) is a gram-positive commensal bacteria that inhabits the gastrointestinal tract of humans and other mamals.  Like other species of the genusEnterococcus, E. faecalis can cause risky  infections in humans, especially in hospital setting.  The presence of Enterococci is enhanced because he had the ability to acquire resistance…

Chemotaxis of Cancer Cells in the Process of Metastasis

Cell motility plays an important role in many biological processes, like cancer metastasis. Of particular importance in these processes is chemotaxis: directed motility towards increasing concentrations of soluble factors. Cancer metastasis is a complex process that involves a number of events, with multiple signals from tumor and stromal cells, the extracellular matrix, and soluble growth…

Phoretic mechanisms for particle motion

Colloids have been a very useful model for description of particle interactions.  With their different shapes and sizes scientists have been able to study phase behavior of particles of those shapes.  Some have been studied by their magnetic dipole moment to study spin interactions.  Some have been studied for their autonomous motion simply caused by…
