In the 1940s and early 1950s, further studies showed inactivation of diverse bacteria, influenza virus, and Penicillium chrysogenum (previously P. notatum) mold fungus using various glycols, principally propylene glycol and triethylene glycol.
In 1938, working with Ernst Boris Chain and Norman Heatley, he read Alexander Fleming's paper discussing the antibacterial effects of Penicillium notatum mould.
The antifungal protein PAF from Penicillium chrysogenum exhibits growth-inhibitory activity against a broad range of filamentous fungi.
Penicillium | Penicillium roqueforti | Penicillium chrysogenum | Penicillium marneffei | Penicillium candidum |
It is related to Penicillium chrysogenum, the source of Penicillin, but not closely enough to ward off infection in those who consume the cheese.
