Cell Wall - Each bacterium is enclosed by a rigid cell wall composed of peptidoglycan, a protein-sugar (polysaccharide) molecule. The wall gives the cell its shape and surrounds the cytoplasmic ... For example, a relatively thick, meshlike structure that makes it possible to distinguish two basic types of bacteria.

The researchers have described in new, precise detail the unique cell extension that forms on one end of the bacterium Mycoplasma pneumoniae. This structure, called a "terminal organelle," performs several tasks for this pervasive bacterium and even acts as a "molecular inch-worm," helping the microorganism move.

The two-minute animated video, which was a scientific visualization of a cell structure from a bacterium, was streamed at a rate of 7.5 gigabits per second with a peak transfer rate of 8.4 gigabits per second. At that speed, the researchers could have transmitted approximately 12 movie DVDs in the same two minutes.
