Question:
Why do mold cultures require a much longer period of incubation than bacteria yeasts?


Replies:
Bacteria are procaryotic cells (no nucleus, mitochondria, golgi bodies, endoplamic reticulum, chromosomes, etc) and can divide in as few as 20 minutes. A bacterial cell is about the size of a mitochondrium. Cells comprising a mold are eucaryotic cells. They contain a nucleus, chromosomes, endoplasmic reticulum and hundreds of mitochondria and therefore take a minimum of several hours to reproduce due to their relative complexity.
