Question 13
Alkaline phosphatase test is used to verify pasteurization adequacy because:

  • It detects added water in milk
Correct Answer Logic:
Alkaline phosphatase (ALP) is a native raw milk enzyme inactivated at \(72^{\circ}\text{C}\) for \(15\text{–}20\) seconds. A positive ALP test in pasteurized milk indicates underpasteurization or post-pasteurization contamination with raw milk.

Bio-Technology QUESTION #10624
Question 20
Which type of bioreactor is most appropriate for immobilised enzyme reactions involving product inhibition?
  • Stirred tank reactor (STR) in batch mode
  • Packed bed reactor (PBR) with plug flow characteristicsβœ”οΈ
  • Air-lift reactor with high recirculation
  • Continuous stirred tank reactor (CSTR) at low dilution rate
Correct Answer Logic:
A packed bed reactor (PBR) is ideal for product-inhibited immobilised enzyme reactions because it exhibits plug flow behaviour β€” substrate concentration is highest at the inlet (reactor entry) and lowest at the outlet. This means the enzyme near the inlet operates under high substrate, low product conditions (high activity); only the enzyme near the outlet is exposed to inhibitory product concentrations. In a CSTR, the entire reactor operates at the low exit concentration, maximising inhibition throughout.
