Question

How will you visually determine if a colony growing on the surface of the PDA, which was inoculated with your cheese sample, is bacteria or yeast?

Answer 1

Bacterial colonies look like Ice Cream Drops. Bacterial colonies grow faster than fungal colonies. Bacterial colonies do not cover the whole surface.

Fungal colonies look a little like a smashed cotton ball. Fungal colonies grow slower than bacterial colonies. Usually, the fungus spreads through all the surface if given enough time.
