Question

Which one of the following is a wrong matching
of a microbe and its industrial product, while the
remaining three are correct ?
(a) Yeast - statins
(b) Acetobacter aceti - acid
(c) Clostridium butylicum - lactic acid
(d) Aspergillus niger - citric acid

Answer 1

The correct answer is c)  Clostridium butylicum - lactic acid

Explanation:

Option "C" is considered right because Clostridium butylicum produces acetone, ethanol, and butanol from starch at the same time. It is also known as "Weizmann Organism". This name was given to it after the Jewish-Russian born scientist "Chaim Weizmann" who used it as a bio-chemical tool to produce these three acids simultaneously. It is considered as a valuable commercially bacterium.  

Answer 2

(c) Clostridium butylicum - lactic acid is a wrong matching  of a microbe and its industrial product.

Clostridium butylicum:

• Clostridium butylicum is a bacteria with many commercial property.
• This bacteria produced butanol, ethanol and acetone jointly from starch. This process is called as ABE process.
• Acetone is used in manufacturing of cordite; and butanol and ethanol is used in manufacturing of fuels.

Lactic acid:

• Lactic acid is produced by Lactic acid bacteria which is a gram-positive and acid-tolerant bacteria.
• This bacteria plays a wide role in decomposition of dairy products.
• The lactic acid produced from this bacteria during decomposition produces carbohydrates as end product.
