Answer:
a bacterium
Explanation:
<em>Penicillium nonatum is a type of </em><em>bacterium</em><em>.</em>
<u>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.</u>
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.
