Which one of the following is a wrong matching of a microbe and its industrial product, while the remaining three are correct?
A
$Clostridium\ butylicum$ – lactic acid
B
$Aspergillus\ niger$ – citric acid
C
Yeast – statins
D
$Acetobacter\ aceti$ – acetic acid
Detailed Solution
$Clostridium\ butylicum$ (a bacterium) produces butyric acid; lactic acid is produced by $Lactobacillus$. So this match is wrong.
$Aspergillus\ niger$ (a fungus) produces citric acid – correct.
The yeast $Monascus\ purpureus$ produces statins, the blood-cholesterol lowering agents – correct.
$Acetobacter\ aceti$ (a bacterium) produces acetic acid – correct.
Hence the wrong matching is $Clostridium\ butylicum$ – lactic acid.
$Aspergillus\ niger$ (a fungus) produces citric acid – correct.
The yeast $Monascus\ purpureus$ produces statins, the blood-cholesterol lowering agents – correct.
$Acetobacter\ aceti$ (a bacterium) produces acetic acid – correct.
Hence the wrong matching is $Clostridium\ butylicum$ – lactic acid.
