Yeast cannot utilize all of the sugars equally well. While glucose, sucrose, and fructose all can be metabolized by yeast, lactose is not utilized at all. Yeast may not have the proper enzymes to either transport lactose across its cell membrane, or it may not have the enzyme needed to convert it from a disaccharide to a monosaccharide.

Is yeast used in making rum?
No.
Can you over rise a yeast bread?
Yes, if yeast dough is left to rise too long, the yeast will consume all of the available sugars. Then the dough will not be able to rise when baking, resulting in a heavy, tough product.
After some time the yeast and no more gas is produced suggest one possible reason why the yeast dies?
One reason yeast dies is that all the sugars in the dough have been consumed. When this happens, the dough goes "sour."
Where does yeast naturally grow?
In any warm moist material that provides nutrients it can consume. Different species and strains of yeast grow on different things: bread dough (leavening), grain mashes (beers, whisky), fruits (wines, rotting), mucus membranes (the disease thrush), etc.
Does yeast eat anything?
Yeasts eat things with sugars in them, then again so does a lot of other micro organisms, so if you want to have yeast remember that yeast is pretty much everywhere all the time. So if you stick a sugar based product in a sealed area, your probably going to find yeast.
Why is yeast used to make beer and wine?
Yeast is used to produce the alcohol in beer and wine. Yeast is a fungus that feeds on sugars to create energy for itself. When the yeast is deprived of oxygen, as it is in the production of beer and wine, it uses a process called anaerobic respiration to create its energy. The byproducts of anaerobic respiration are ethanol (alcohol) and CO2. This production of alcohol via yeast is called fermentation. Yeast is used in the production of virtually all Alcoholic Beverages.
Are bananas okay on a yeast-free diet?
No, bananas have lots of sugar. If you are doing a yeast free diet to deal with a yeast infection or some other kind of yeast overgrowth in your system then you should avoid all sugars, which yeast readily feed on. If you are doing a yeast free diet to deal with a yeast allergy, you may or may not have to give up bananas. Usually fruit can be reintroduced after a certain period of time, so not to worry.
How yeast help in fermentation?
Yeast reacts with heat and water making it rise to give the bread a even and nice texture. The yeast breaks down starches (as in flour) and turns the starches into glucose, fructose, and maltose. The yeast then grows on these sugars, converting them into alcohol and carbon dioxide which causes the bread to rise.
What happens to milk when yeast is added to it?
Milk, rice milk and soy milk are yeast-free products
What happened when you mix the yeast in dough?
Dough for bread only heeds yeast if you want to make light fluffy bread. If you want to make "hard tack" or "zwieback" or "matzos" then you can forgo the rising agent (yeast). Yeast converts carbohydrates (sugars and starches) into alcohol and carbon dioxide. The alcohol evaporates and the CO2 gets trapped in the pockets of dough (thanks to a large degree to the gluten in wheat). These pockets of gas remain after baking making the bread light and tasty.
What will happen when you put yeast in warm water?
You absolutely cannot boil yeast if you are using it for baking because boiling it will "kill" it. It will no longer make whatever you put it in rise, so it will be the same as not using it at all.
Is every liquor vodka at origin?
No, all liquors are formed through the same process. Sugars are fermented by yeast. The results is a beer or wine or the basis for distilling a liquor. The original source of the sugars that are fermented, as well as the distillation and aging processes create the unique flavors of different liquors.
