Mold happens in places that are dark, and moist, and places with pores just like sponges or bread. Mold works when two small spores on the bread reproduce. The best way to make sure bread doesn’t get any mold is by putting it in a cool, dry place, if you plan to eat it within a couple of days. The other way would be by freezing the bread after wrapping it in plastic. Bread gets moldy because it provides a good source of food for some types of fungus. The air is usually full of tiny mold spores, and sometimes they can go on nearly anything organic to digest it. In bread, the enzymes which are in the proteins from the bread that speed up chemical reactions in the bread cells. When it happens the cell walls of the organic material or the bread making up the loaf makes the mold to come out. This is how bread gets moldy. William Yobe discovered mold in 1827, then Alexander Fleming grew the mold in pure culture. Molds are a type of fungi. Fungi are organisms composed of masses of tubes or filaments, called hyphae. Fungi do not produce their own food like plants. They need to get their food from their surroundings. They get their food by hiding the digestive enzymes or proteins to dissolve organic and inorganic food materials.
Growing bread mold is not hard to do. You can use a slice of bread that has been rubbed along the floor or other dusty surface, and give it a couple of squirts of water from a spray bottle to moisten it. Place the bread in a sealed bag and leave
