Many would consider this to be one of the greatest and most important medical discoveries of all time. Penicillium notatum is what type of organism?

Answer 1

Answer:

a bacterium

Explanation:

Penicillium nonatum is a type of bacterium.

Bacteria are prokaryotic, microscopic organisms that are capable of adopting different lifestyles based on their mode of nutrition. While some are capable of manufacturing their foods via photosynthesis/chemosynthesis, some are saprophytic in nature while others lives as parasites on living organisms.

Those that lives as parasites are often capable of causing diseases and are therefore called pathogens.

Penicillium nonatum is capable of producing a substance that has the capacity to inhibit the growth of another bacteria. Substances that are capable of inhibiting or killing bacteria are generally known as antibiotics.
