QUESTION
Stormy fermentation of milk is produced by?
OPTIONS
(A) Str. Faecalis
(B) Cl. welchii
(C) E. coli
(D) Shigella sp.
ANSWER
(B) Cl. welchii
EXPLANATION
Stormy fermentation is a characteristic reaction produced by Clostridium perfringens, historically called Clostridium welchii, in milk media; rapid acid and gas production disrupts the clot. Streptococcus faecalis, E. coli, and Shigella do not produce the classic stormy clot reaction. Hence, option (B) is correct.
