mold bread has green fungus growing out of it. stale means old but stiff and hard...i think
Eventually it can do that. Mold can grow on bread as well as any other food. Airborne mold spores only require a moist environment to thrive and colonize. This process is not as rapid though as compared to mold forming on food in a warmer environment.
Yes
Yes they can. Just like whole loaves of bread and slices of bread, bread crumbs can expire.
No. That substance is called mold.
i think stale bread is not necessary but fresh bread
One can throw stale bread out in the garbage.
The bread tasted stale after sitting out for a few days.
Type of bread
No. Bread mold grows on bread, hence the name.
Freshly baked bread will go moldy much quicker and should be kept in a cool place. Many breads bought in the store can stay on the counter for a week or more. However, if you think of it, what chemicals are in that bread to make it last so long in a warm area? I would rather have good bread and keep it in the fridge.
White bread is wheat bread, so yes, bread made from different types of wheat flour would grow similar or identical molds, depending on exposure to various types of mold spores.
Bread mold is not a living organism and does not get nutrients from bread.
