Alcohols are important industrial solvents. Ethanol, methanol, propanol and butanol are produced commercially by fermentation activity of some fungi, majorly yeasts. During fermentation, yeast cells convert cereal derived sugars into ethanol and $CO_2$ At the same time hundreds of secondary metabolites that influence the aroma and taste of alcohol are produced. Sugar concentration affects the rate of fermentation reactions. Yeast cannot grow in very strong sugar solution. In case of complex carbohydrate containing nutrient media, 1% malt or Rhizopus is used along with yeasts. Hydrolysis of starch is carried out at high temperature for 30 ruins. 'Tile crushed food mixed with hot water for obtaining malt in called mash. 'Tile nutrient medium prior to fermentation in called wort. Wort is cooled down to appropriate temperature and inoculated with strain of yeast.
  1. Tile rate of alcohol production is measured on the basis of:
  1. Amount of sugar present in the medium.
  2. Amount of $CO_2$ produced per unit time.
  3. Amount of yeast added in the medium.
  4. All of these.
  1. A number of chemicals are produced at the time of alcoholic fermentation with the change of nutrient media, pH and aeration. Select such by-product from the following.
  1. Phenylethanol.
  2. Amyl alcohol.
  3. Glycerol.
  4. All of these.
  1. During alcoholic fermentation of cereals and potato, the crushed food mixed with hot water for obtaining malt is called:
  1. Juice.
  2. Mash.
  3. Wort.
  4. None of these.
  1. Distilled alcohol with 95% ethanol content is called:
  1. Absolute alcohol.
  2. Rectified spirit.
  3. Gin.
  4. Brandy.
  1. Assertion: Rhizopus or 1% malt is used in the nutrient medium when it contains complex carbohydrates.
Reason: Yeast does not possess sufficient diastase or amylase.
  1. Both assertion and reason are true and reason is the correct explanation of assertion.
  2. Both assertion and reason are true but reason is not the correct explanation of assertion.
  3. Assertion is true but reason is false.

Read the following and answer any four questions from 9(i) to 9(v) given below:
Bioreactors are considered as vessels in which raw materials are biologically converted into specific products by microbes, plant and animal cells or their enzymes. They are used for large scale production as they provide optimum growth conditions such as temperature, pH, substrate, vitamins, oxygen and salts for obtaining desired product. Most commonly used bioreactors are of stirring type which include simple stirred tank bioreactor and sparged stirred-tank bioreactor.
  1. Bioreactor are useful in:
  1. Amplifying a gene.
  2. Isolation of genetic material.
  3. Processing large volume of culture.
  4. Infecting DNA in a cell.
  1. Which of the following is essential to obtain desired product in a bioreactor?
  1. Size of the bioreactor.
  2. Sterile condition.
  3. Quantity of the raw material.
  4. All of these.
  1. Assertion: The stirred-tank is well suited for large scale production of microorganisms under aseptic conditions.
Reason: In sparged stirred tank bioreactor, surface area for oxygen transfer is increased.
  1. Both assertion and reason are true and reason is the correct explanation of assertion.
  2. Both assertion and reason are true but reason is not the correct explanation of assertion.
  3. Assertion is true but reason is false.
  4. Both assertion and reason are false.
  1. Growth condition that could affect the quality of obtained product in a bioreactor are:
  1. Temperature and pH only.
  2. pH and oxygen supply only.
