Until the mold has consumed all of the bread and all you are left with is the mold.
The only danger is it will taste funny. It will spoil like bread (not that artificially enhanced sliced white goo that they call bread) and will begin growing mold in a day or two.
Bread molds vary widely in species. However, most kinds of mold that grow on wheat bread are harmless in small amounts. (White bread is a kind of wheat bread, as opposed to something like rye or oat bread.) However, there are certain kinds of bread mold that can be dangerous, but any bread mold is bad in large amounts. Also, some people may have an allergic reaction to mold. It's a good idea to generally stay away from bread mold.Note: The above information refers to eating bread mold. Inhaling the spores can be much more dangerous.
I imagine it has to do with the higher sugar content of white bread.
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.
until the food decomposes or gets eaten.
One explanation could be, that there is more sugar in white bread, than sourdough bread. Since sugar equals energy, the mold can grow faster. An other explanation could be, that it is different fungi living on the two types of bread. And even though molds are speedy little things there can, as you see, be a difference. The true molds (often white and very fluffy) being the fastest, while other types of filamentious fungi, like the green spots on the bread, is a bit slower. The green spots on the whole grain sourdough bread is often of the same genus of fungi as used to make blue cheese. So don't forget your sourdough sandwich with blue cheese or the fungus will have eaten it all before you can eat all of it! This still does not mean that you should eat bread infected with mold. There is no way you can see if it is an eatable one or one of those (many) that makes toxic compounds. Always throw moldy food away - all of it.

No. Emulsifiers simply make sure that two things that don't normally mix, stay together, like mustard in a vinaigrette.
Probably about 2-4 days. It doesn't stay good that long.
ya ummm who would wanna no that???? just sayin!! its kinda gross :( it would most likely rot outside the frige because the heat outside would probly heat up the food which would cause to mold or rot inside the frige it would probly stay fresh because like you probly know if something is cold it would stay fesh so you answer would be it would stay fresher or in other words not mold if it is in the frige but if not it would mold faster

Homemade Italian bread is really going to stay good only about a day. It might not get moldy for a few days, but it will start to stale and become hard.
