Yes. Special beer- or wine-making yeast are selectively bred for taste and alcohol tolerance, but I have been using ordinary baking yeast for home brewing for years, with great results.
yeast
Bread. Without it, the bread would never rise.
yeast is the thing that makes bread fluffy
To create a yeast starter for bread, mix flour and water in a jar, then add yeast. Let it sit at room temperature for a few days, stirring occasionally. The mixture will become bubbly and active, indicating that the yeast is ready to use in bread dough.
alcohol
Yes, because it can respire in water. This can be proved as to make bread people put yeast and that yeast can respire in water as batter has water. Respiration in yeast- C6H12O6----> C2H5OH + 2CO2 + Ethyl Alcohol/ethanol
No, not all bread contains yeast. Some breads, like unleavened bread, are made without yeast. Yeast is used in many bread recipes to help the dough rise and create a light, fluffy texture, but there are also breads that are made without yeast, such as flatbreads or quick breads.
Yeast fermentation converts sugars into ethanol. To make yeast from ethanol, you would need to reintroduce the ethanol to a suitable yeast culture medium that contains essential nutrients for yeast growth. The yeast will consume the ethanol as a carbon source and begin to multiply, adapting to grow in the ethanol environment.
To create a yeast bread starter, mix flour and water, let it ferment, and feed it regularly. To maintain it, store in a warm place, feed it with flour and water, and use it to bake bread regularly.
You can put yeast in bread dough to help it rise, in beer or wine to aid in fermentation, and in pizza dough to create a light and airy crust.
Alcoholic fermentation is a metabolic process in which yeast cells convert sugars into ethanol and carbon dioxide. An example is the production of beer, where yeast ferments the sugars in malted barley to create alcohol. Another example is the production of wine, where yeast ferments the sugars in grape juice to produce alcohol.
Beer yeast can be used to make bread by activating it in warm water with sugar, then mixing it with flour and other ingredients to create dough. The yeast ferments the sugars in the dough, producing carbon dioxide gas that causes the dough to rise and create a light, fluffy texture in the bread when baked.
