Question

Which of the following is called Baker’s yeast and Brewer’s yeast?

• A. $Rhizopus$
• B. $Mucor$
• C. $Penicillium$
• D. $Saccharomyces$

Answer 1

The correct option is D $Saccharomyces$

Baker's yeast :
Baker's yeast is used in the production of bread and other bakery products. The most commonly used yeast for this is $Saccharomycescerevisiae$, which acts on fermentable sugars present in the dough, releasing ethanol and carbon dioxide.
After alcohol fermentation of the dough, it is baked. The carbon dioxide that is trapped escapes because of the heat, giving the bread porosity.

Brewers yeast :
Brewers yeast are those used in breweries in the production of beer. The yeast used, $Saccharomycescerevisiae$, acts on cereals like barley, hops etc. (raw material) fermenting it into ethanol and carbon dioxide through the alcohol fermentation pathway.
The ethanol produced at the end of fermentation is suitably processed to form beer.


Final answer
(C) $Saccharomyces$
