Question

Glycocalyx dessication

Answer 1

EPS and glycocalyx are terms used to describe the polysaccharide produced by bacterial cells. EPS refers to one of the major components of biofilms, and gly-cocalyx refers to the polysaccharide matrix surrounding individual cells. EPS has an important role in biofilm structure and function and has a complex physical and chemical nature. Its functions are mostly protective in nature and this is one of the benefits for bacteria in the sessile state. Because the glycocalyx is the outermost component of bacterial cells, this layer mediates virtually all bacterial associations with surfaces and other cells: it dictates location, juxtaposition, and the eventual success in the ecosystem.

EPS production may be a direct response to selective pressures in the environment and may protect against desiccation (by binding water molecules) and predation by feeding protozoa. It also provides protection against antimicrobial agents, including antibiotics, bio-cides, and host defense mechanisms. This defense may occur by means of a physical barrier or through aiding the bacteria to evade phagocytosis. Other advantages for bacteria of EPS derive from its polyanionic nature, which confers on the biofilm some ion-exchange properties that assist entrapment and the concentration of nutrients, the removal of toxins, and the exchange of metabolites within the consortia. Finally, the close proximity of cells within the biofilm allows plasmid transfer and an alteration in phenotypical characteristics as a response to changes in the environment
