How did Alexander Fleming prove that penicillin is harmless to human cells?

Fleming discovered the common factor in the fluids was an enzyme. He named his newly discovered enzyme lysozyme. The effect of lysozyme was to destroy certain types of microbe, rendering them harmless to people. The presence of lysozyme in our bodies prevents some potentially pathogenic microbes from causing us harm.

How did Alexander Fleming accidentally discovered penicillin and antibiotics?

In 1928 Dr Alexander Fleming returned from a holiday to find mould growing on a Petri dish of Staphylococcus bacteria. He noticed the mould seemed to be preventing the bacteria around it from growing. He soon identified that the mould produced a self-defence chemical that could kill bacteria.

How penicillin was discovered identify the problem?

One day in 1928 he discovered that bacteria he had been growing on a culture plate had been killed in an area close to where a mould was accidentally growing. He isolated the mould and showed that it released a substance that inhibited bacterial growth. He named the substance penicillin after the name of the mould.

Was penicillin an accident?

What was the problem that Fleming was trying to overcome?

Answer: Fleming, being a bacteriologist, was searching for cures to treat bacterial infections. One day in 1928 he discovered that bacteria he had been growing on a culture plate had been killed in an area close to where a mould was accidentally growing.
