Jack Strominger recounts his seminal work and contributions to understanding bacterial cell wall components, and thus how penicillin functions, and the implications of these discoveries for ...

First, gram-negative bacteria have a thin cell wall that is about 1.5 to 10 nanometers across, whereas gram-positive bacteria have a thick cell wall measuring about 20 to 80 nanometers.

These compounds are small enough to pass through the bacterial cell wall. Glycerol can be converted into a glycolysis ... olive oil and produce a halo around the bacterial growth. The Gram-positive ...
