the development of penicillin flowchart


In the typical penicillin fermentation there is a growth of 10 hrs duration with a doubling time of 6 hrs during which the greater part of the cell mass is formed. The oxygen supply in the growing culture is critical since the increasing viscosity hinders oxygen transfer. After growth phase, the culture proceeds to actual penicillin production.

This shifted pharmacological research towards the development of semisynthetic, beta-lactamase-resistant penicillins (i.e. second generation penicillins): oxacillin, methicillin, and dicloxacillin, also defined as anti-staphylococcal penicillins, due to their ability to resist penicillinases present in staphylococci.

The Penicillin Problem. The story of Alexander Fleming's discovery of penicillin has been told often. Fleming was already well known for his earlier work on staphylococci when, upon returning from a long holiday in September 1928, he noted that one petri dish contained colonies of Staphyloccus except for clear area contaminated with a fungus that appeared to inhibit bacterial growth.
