This view is supported by an experiment Fleming conducted where he added penicillin extract to blood in a test tube.
Florey’s predecessor, George Dreyer, had written Fleming earlier in the 1930s for a sample of his strain of Penicillium to test it for bacteriophages as a possible reason for antibacterial activity (it had none). However, the strain had been saved at Oxford.

While working at St Mary's Hospital in London in 1928, Scottish physician Alexander Fleming was the first to experimentally determine that a Penicillium mould secretes an antibacterial substance, which he named "penicillin".
Sir Alexander Fleming FRS FRSE FRCS [1] (6 August 1881 – 11 March 1955) was a Scottish physician and microbiologist, best known for discovering the world's first broadly effective antibiotic substance, which he named penicillin.
