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 – Acetic acid C Clostridium butylicum – Lactic acid D Aspergillus niger – Citric acid
Statins are a class of drugs used to lower cholesterol levels by inhibiting the enzyme HMG-CoA reductase, which plays a central role in the production of cholesterol in the liver. It is produced by the yeast in large scale. Acetobacter aceti is a gram-negative bacterium and proved it to be the cause of conversion of ethanol to acetic acid and thus, used for the large production of acetic acid. Butyric acid is a product of the organism Clostridium butylicum and lactic acid is produced by the lactic acid bacteria. Aspergillus niger is a fungus and is used in the industrial preparation of citric acid and gluconic acid. Therefore, the correct answer is option C.
