One of the most important scientific discoveries was penicillin. Research the discovery of penicillin, what produces this drug,
artcher [175]

Answer:

It is essentially a broth culture filtrate of the penicillium mould.

Explanation:

  • Alexander Fleming invented penicillin an antibiotic in 1928. These have been rated as the most important scientific discovery, being among the first antibiotics to be effective against bacterial infection.
  • Penicillin belongs to different families that are selective against a large variety of bacteria.
  • In fact, this antibiotic was discovered by fleming and accident in which he left a platter containing staphylococci open and was contaminated by green mould. There was an area of inhibited bacterial growth around the mould from which he inferred that the mould produced a material that inhibited bacterial growth. This was found to be a penicillium mould through further study.
  • I assume penicillin is the most significant discovery so far because it was the first antibiotic ever discovered against bacterial infection in the absence of any drug.
