It is important to note that,population continues to decrease in rural areas and increase in urban areas.This is attributed to certain factors that are pushing people out of r â¦ ural areas and pulling them to the urban centers.
1 The outer surface of cells is often covered in a polysaccharide or protein material called glycocalyx. 2  Glycocalyx can be formed from protein, polysaccharides, polyalcohols or amino sugars.3  Glycocalyx can function in attachment, protection from desiccation, and protection from attack by a hosts immune system.he general term for any network of polysaccharide or protein containing material extending outside of the cell is the glycocalyx. Many bacteria produce such a coating on the outside of their cell, and they come in two types: capsules and slime layers. The difference between the two is somewhat arbitrary.
The glycocalyx of bacteria can assume several forms. If in a condensed form that is relatively tightly associated with the underlying cell wall, the glycocalyx is referred to as a capsule. A more loosely attached glycocalyx that can be removed from the cell more easily is referred to as a slime layer.he second function of a bacterial glycocalyx is to promote the adhesion of the bacteria to living and inert surfaces and the subsequent formation of adherent, glycocalyx-enclosed populations that are called biofilms.
