If in your experiment, whole wheat bread has molded faster than other breads, you should look at the ingredients used to make the bread and the processing conditions where the bread was produced. The wheat bread could have been exposed to more mold to begin with or the other breads may have used mold inhibitors.
Oh, dude, mold doesn't care if your bread is store-bought or homemade. Mold is an equal opportunity invader, it'll happily chow down on any bread left out too long. So, whether you're munching on fancy artisanal loaves or budget-friendly supermarket slices, just make sure to store them properly and eat them before they turn into a science experiment.
There could be many reasons, including # You picked a bread that contains mold inhibitors # The bread did not get inoculated with mold # The experimental conditions are not conducive for mold growth (too dry, too hot, too wet, too cold) Sometimes looking at the reason for failure can be even more enlightening than having the experiment succeed.
Bread mold is harmful because of the mycotoxins that may be present in the spores of the mold. This type of mold when processed can also be helpful as it is used to produce penicillin.
Bread mold grows best in warm and wet areas.
