NEET BIOLOGY

Detailed explanation-1: -The yeast S. cerevisiae is the organism of choice for the industrial production of ethanol and, as such, represents the largest industrial biotechnological utilization of yeast.

Detailed explanation-2: -The yeast Saccharomyces cerevisiae, also known as brewer’s yeast, is used for fermenting malted cereals and fruit juices to produce ethanol (ethyl alcohol).

Detailed explanation-3: -Yeast is used for commercial production of alcohol and wine.

Detailed explanation-4: -Detailed Solution. The correct answer is Saccharomyces cerevisiae. In the commercial production of ethanol, Saccharomyces cerevisiae is used as yeast because it can tolerate a wide range of pH thus reducing the risk of infections during the process.

Detailed explanation-5: -Summary: Why do some yeast cells produce ethanol? Scientists have wondered about this apparent waste of resources for decades. Now scientists think they have a solution: yeast cells produce ethanol as a ‘safety valve, ’ to prevent overload when their metabolic operation reaches a critical level.
