Q&A for How to Make Mold Grow on Bread

If the plastic is not sealed, your bread may dry out. Mold needs moisture to grow. Additionally, an open bag may cause the spread of mold spores into the atmosphere which can be potentially harmful to the human body.

While some pharmaceuticals are derived from mold (e.g., penicillin), regular mold cannot be used as a medicine as is. You would need to know the type of mold you have (species name) and would also have to process the mold scientifically to create a medicine suitable for human use.

Lightly moistened bread stored in a warm, dark place should grow mold in about 7-10 days.

If you were performing this experiment, you might ask what environment allows the mold to grow fastest? If you did some research, you would see that mold grows best in a warm, damp environment. Knowing this, a testable hypothesis would be: The best environment to grow mold is one that is both warm and damp.

Probably under your sink or in any closet or cabinet. Make sure you put a lock on the cabinet or closet if you have small children or pets that could get into it.

Mold needs dampness, warmth and a food source.

Your bread might have dried up or it was to cold for it to grow. You may want to start over with new bread.

Light does not affect mold growth in any way, as only temperature, humidity, and nutrition make it possible for mold to grow.

You can take a wet paper towel and put it over the bread in a bag for dampness.

Dry bread will eventually grow mold, but it will take much longer.

About 1 spray or until it's coated with water, but make sure it's not so wet that it gets soggy.

Mold gets its color from a pigment called melanin, which acts as a barrier to other molds.

Much longer, as dry bread will grow stale. If you are doing a science experiment, provide moisture for it to grow quicker.

Illustrations can found on the internet (by search via Google or Wikipedia) or by going to your local library and finding a book on mold growth. The internet would be quicker and easier though.

One would typically do this as a science project.

It takes 1 year for mold to grow on bread in the fridge. If you keep it in a Ziploc bag it will take another year for mold to grow on it.

The bread will get dry and the experiment won't work. If that happens, you'll have to start over.

Anything fresh, for quicker results don’t buy your bread from a box store grocery. Go to a bakery or bake it yourself.

The process takes about 7 - 10 days.

No because it takes 7-10 days for the mould to grow. The mould needs to go through the process of growing the spores and reproducing.

Mold grows because in the air spores are present. If some spores fall in the damp or any material, then mold grows. Mold also grows easily in warm and moist areas.

Even if the temperature is 20 degree Celsius the mould will appear on the bread after keeping it for 10 days. Remember to sprinkle water on the bread.
