How Does Bread Mold Form?

Bread mold is a kind of fungus that usually forms on the surface of bread. This fungus causes the bread to lose its nutrients from the spot where it is present. It is formed due to the presence of moisture on the surface of the bread and once it sprouts it keeps on growing and spreads from the original spot to the whole surface of the bread.

There are many different kinds of fungi in the environment and the bread can catch one of them when exposed to the air. As the bread has some moisture and is also nutrient, the mold would start growing and spreading on the surface of the bread.

 

Mold spores floating in the air, (dust) latch on to a potential food source, preferably something moist and warm. Since it can’t produce its own food, it then emits juices to digest it, and grows hyphae, which are microscopic roots in the dissolved food

This may not be true for bread but I found out an interesting fact. Some mold is actually Penicillin in it's raw form.
