Baker's Yeast
Baker's yeast is a leavening agent used in baking bread. Use of this leavening agent in bread-making results in a light and tasty bread. Without yeast, bread has a heavier texture, is less tasty and often called flatbreads.

Is the same type of yeast used for everything?
Yeast is a general name for a family of bacteria. They are part of the fungi family, and there are currently about 1500 strains known.
Bread making commonly uses the Saccharomyces cerevisiaestrain, while in the making of wine different starins actually effect the taste of the wine.
This is because alcohol, a by-product of yeast feeding on sugars kills yeast, so a yeast that can tolerate higher levels of alcohol will use more of the sugars, giving a 'dryer' taste. While strains of yeast that are less tollerent to alcohol will use less of the sugars, making for a sweeter wine.
What is the reason for knocking back yeast dough after the first proof?
Because there is a lot of air in it; and you want to knock it down, because it is going to continue to grow. If you allow too much air to be in the dough, you will have large holes in your final product.
Is there yeast in the eucharist?
Not typically. In most cases, it is unleavened bread. Although some denominations use a leavened bread instead.
What is yeast sometimes known as?
Yeast is sometimes known as, Balm, as used in brewing and bread making.
Yeast expands because in the heat, it eats and digests sugar, and then it produces carbon dioxide gas.
Bud Light ... like all beers, or any other alcoholic beverage for that matter ... is produced using yeast. The yeast is what converts the carbohydrates in the mash into alcohol; without yeast you don't get beer, you get grain-ade. (Okay, true confessions: it would be possible to produce alcohol using synthetic enzymes or something like Zymomonas mobilis instead of Saccharomyces cerevisiae, but I don't know of any commercial beers actually produced that way ...synthetic enzymes would be expensive, and Z. mobilis is regarded as a contaminant that makes beer taste and smell bad.)
That said: pretty much all commercial beers are filtered to remove sediments, and this generally gets rid of any residual yeast as well. So there's yeast involved in the production, but there should be no (or at least very little) yeast in the finished product.
Home-brewed beer is far more likely to contain leftover yeast than any commercially bottled product.
How does yeast produce yeast carbon dioxide?
It creates it when it "eats" the sugars in the flour mixture
What phylum does yeast belongs to?
The "true yeasts" are in phylum Ascomycota. There are some organisms commonly called "yeast" in Basidomycota as well.
Where can one find information on red yeast rice?
Red yeast rice is what is used to give Peking duck it's red color. You can find nutritional information for red yeast rice at sites such as AltMedicine and WebMD.
No, especially not if the cooler is cool. Yeast survives and reproduces "with an optimal temperature range of 30°-37°C (86°-98.6°F)" (http://en.wikipedia.org/wiki/Yeast). Any temperature significantly above or below this will not allow yeast to survive.
What is the role of the yeast?
The various kinds of yeasts are used in the brewing of beers and in wine making for the production of alcohol and carbon dioxide. The carbon dioxide is especially important in baking and bread making to make the bread dough rise before baking.
What substances are produced in anaerobic respiration in plants and yeast?
oxygen-air we breath
and gluecose-sugar in food
What is special about nutritional yeast?
Nutritional yeast is special because it is a deactivated yeast which is sold in stores as a food product. It is a popular health food, especially for vegetarians.
How did you spend your last weekend. Write a paragraph about your activities?
My last weekend was not so special. It was just like a normal weekend, except I met with my old college friends and we went to McDonald's located very near my residence. We brought some shakes and fast food. I enjoyed it a lot because they are all are my old friends. We've known each other for at least a decade, but now we are all are working professionals and rarely get to get together.
A yeast suspension is made by mixing yeast cells with a liquid.
What causes the bubble increase in yeast fermentation experiment?
why is it reasonable that, of the three sugars, glucose would result in the most activiity suring the fermentation experiment
When bacteria perform fermentation what waste product is formed?
It depends on the type of substrate used; in alcohol or ethanol fermentation carbon dioxide is produced as byproduct. whereas in case of baker yeast CO2 is the sole product!
