Answer 1

The correct option is (b) False

Best explanation: The given statement is false. Microbial growth indicator is the one which indicates the first order kinetic growth of a spoilage microorganism. It uses pH dyes and all dyes reacting with certain metabolites (volatiles or non volatiles). Whereas, pathogenic indicator is the one which indicates the presence of toxins producing pathogenic microorganisms which may or may not cause spoilage, but can cause disease.
