Question

Match the following (column-I with column-II):

	Column I (Microbes)		Column II (Organic acid)
a.	Aspergillus niger	(i)	Butyric acid
b.	Clostridium butylicum	(ii)	Citric acid
c.	Acetobacter aceti	(iii)	Lactic acid
d.	Lactobacillus	(iv)	Acetic acid

• A. a-(i), b-(ii), c-(iii), d-(iv)
• B. a-(ii), b-(i), c-(iv), d-(iii)
• C. a-(ii), b-(iv), c-(iii), d-(i)
• D. a-(iii), b-(i), c-(iv), d-(ii)

Answer 1

The correct option is B a-(ii), b-(i), c-(iv), d-(iii)

Aspergillus niger is a fungus producing citric acid.

Clostridium butyricum are Gram-positive bacteria that produce butyric acid.

Acetobacter aceti uses sugars and alcohols for it's carbon source and turns them into their acetic acid.

Lactobacillus is a genus of Gram-positive, facultative anaerobic, rodshaped, non-spore-forming bacteria. They convert sugars to lactic acid.
