QUESTION
Bacteriological status of milk judged by?
OPTIONS
(A) Reductase test
(B) MBR test
(C) Alizarine test
(D) Catalase test
ANSWER
(B) MBR test
EXPLANATION
The methylene blue reduction (MBR) test provides an indirect estimate of the microbial load of milk because bacterial metabolic activity reduces the dye; faster decolorization generally indicates poorer bacteriological quality. Alizarin and catalase tests assess different quality attributes, while “reductase test” is a broader description rather than the specific test requested. Thus, option (B) is correct.
