HOW LONG DOES IT TAKE TO GROW MOLD ON BREAD?

Question: We are trying to grow mold on bread for a science experiment. It's been 3 days and still nothing. How long does it take before visible spores start to develop. Answer: You may not be getting mold because the bread may have preservatives that prevent bacterial growth. Bread without preservatives (sodium propionate) is a wonderful medium for growing mold. Here are some tips to harbor the growth of mold:Check the ingredients of the bread, we want white bread without propionates.Put five to 10 drops of water on the piece of bread and store it in a Ziploc bag in a warm place. After seven to 10 days, you should notice some fuzzy white, black, orange or green spots on the bread. The green color is typically a mold called Penicillium (from which penicillin is made). Once visible, the mold will grow noticeably each day.
