Making penicillin is not brain surgery or rocket science --- its harder !

Humans still can't make penicillin or most other beta lactam antibiotics.

At least, we can't make them anywhere as cheaply and as environmentally friendly as can the small, weak, under-rated (and frankly second or third rate) penicillium slime.

This is something worth remembering when we explore why Dr Martin Henry Dawson did not have a preferential option towards the poor, weak and small ---- all impressions garnered during WWII to the contrary.
