I'm pretty sure it's both, because while yeast and flour mixed with water smells alcoholic (which is a sign of fermentation), when it's mixed with yeast and water it smells like milk. Also, it barely grows, less than just yeast and water.
Correct me if I'm wrong!
Salt retards the growth of yeast, and salt in too high concentrations can kill the effects of the yeast. With too little salt, the dough when cooked will be filled with air pockets, causing holes to appear throughout the bread.
maybe, but for fact heat over 175 Fahrenheit kills yeast
Salt isn't toxic to yeast. Too much salt will kill most cells, though... it's not necessarily a chemical reaction; it could be through osmotic pressure.
Salt is not made from yeast.
No
Yes, it kills most germs.
Live yeast can be used to inflate a balloon if you give the yeast something to ferment (such as sugar). They then produce carbon dioxide as a waste product that could inflate a balloon. You should not expect it to be buoyant, however, for CO2 is heavy as gases go (considerably heavier than air, for instance). The yeast cannot use salt for much of anything, however.
Most of the time, Ultraviolet radiation will kill or badly hurt most yeasts. As there are so many different kind of yeasts, each different kind of yeast will have a different reaction to this kind of light. There are also certain mutations that may cause yeast to be ultraviolet light sensitive or resistant.
No. It is a yeast, that's all.
If you mix salt with yeast, the rise of the dough will be slowed down and the salt can kill the yeast.
Bleach will kill yeast. Salt can slow the growth of yeast or stop it all together. Sodium benzoate and potassium sorbate can also kill yeast.
In yeast breads, salt limits the action of yeast by killing it. If you have too much salt, you might kill the yeast too quickly. The bread might also taste salty. In quick breads (those that rise with baking soda and/or baking powder), salt is used to add flavor, so too much salt will just make the bread taste more salty.
As anyone who bakes bread, or brew wines and beers will know, yeast needs a moist, warm environment in which there is dissolved liquid sugar available (not salt). The yeast cells rapidly multiply as the yeast feeds off the sugar, and gives off carbon dioxide gas and alcohol. It is the carbon dioxide gas that will inflate the balloon. Salt would probably kill off the yeast.
Yeast Grows much better in sugar water. They are micro organisms that need the sucrose in the sugar to activate and grow, without the sugar very little would happen. If you used salt water it would most likely kill the yeast.
The yeast die.
Yeast is a living organism. Salt, sugar and flour are compounds that are not alive.
The salt will bust the yeast cells killing it. Thus the yeast will be useless and not product the gas that is needed for the dough (bread) to rise.
They put flower,eggs,and salt in the yeast bread.
No.
Yeast is not a bacterium, but you can kill some of them with some antibiotics. Antibiotics that are effective against yeast are usually called antifungals.
Directly regulated by sugar and salt. Sugar cuases yeast growth, salt slows. Environmental factors such as moisture, heat and acidity also affect yeast growth.
