What is the Difference Between Bacteria And Mold?

Jackson Kung'u

Questions:

I found black spots on the outside part of the neck of a plastic bottle of wine. They evolved over time into mushy, mold looking marks. I was told they were bacteria and so harmless. My questions are:

  1. What is the difference between bacteria and mold?
  2. Can bacteria actually grow into “beard-looking” stuff?
  3. Is it really safe?

Many thanks.

Answers:

  1. The main differences between molds, which are fungi, and bacteria are:
    • Fungi have a proper nucleus in their cells and bacteria do not.
    • Fungi are eukaryotes, that’s their DNA is enclosed in a nucleus which is separated from the cytoplasm by a nuclear membrane, bacteria are prokaryotes, that’s their DNA is not sepatated from the cytoplasm in a nucleus.
    • Fungal cells are complex while bacterial cells are simple. Fungi have structures in their cells such as mitochondria which bacteria do not have.
  2. Bacteria mainly exist as single cells. However, a few are filamentous and therefore may grow into “beard-looking” stuff
  3. It’s not safe to drink or eat anything contaminated by microorganisms. While not all microorganisms are harmful, there very high chances that a harmful bacterium or fungus could be present.

The Indoor Mold Is An Early Warning Device

The mold (or mould, in the Queen’s English) has been the victim of a bad press. Mention the word and it conjures up an image of something rotting or in the process of decomposition. And yet, were it not for the mold that inspired the discovery of penicillin millions of lives would have been lost. […]
