Not all do. But some can form it if they find the protien inside the foods you eat.

cells
Proteins many times line the outer surface of cells. These are used in diffusion and also provide support for the cell.
Outer boundary of a cell is formed by a cell wall in plant cells and a cell membrane in animal cells. However in some cases animal cells can have a cell wall, but it is not made of cellulose as it is in a plant cell. It is mostly made of proteins.
The capsule of the bacterium can protect it from phagocytosis by white blood cells. The capsule is a thick, outer layer made of polysaccharides that can make the bacterium difficult to engulf by phagocytes, thus enabling it to evade the immune response.
Proteins (in short supply) interact with specific receptors on the cells outer membrane, triggering a cascade of events, which leads to the expression of specific genes and the production of the protein.

An autotransporter is a structural domain found in some bacterial outer membrane proteins.
the cell wall.
To match and dock with proteins on the outside of cells they are going to enter.
There is a cell wall.It is made up with peptidoglycan.

Because 70% is a strong enough concentration to lead to the disintegration of the outer bacterial plasma membranes, eventually denaturing proteins and killing off bacteria. We do not tend to use 100% ethanol (one would think it to be more effective) since this could kill off the bacteria, however it may preserve the genetic material of the bacterium, which may be transferred to other bacterial cells. This is to be avoided when culturing cells, for example.

Structural polysaccharides are the polysaccharides that are found to form the structure of an organism. Eg. Cellulose - in plants Chitin - found in outer skeleton of insects and crabs Lignin - wood

Sure. After all, it's a cell, and most all cells have some sort of protective/permeable membrane. Of course, you have to take into consideration that not just bacterial cells have a membrane, many other types of [harmless] cells have membranes, too. Hope this helped, Lovetta...
