Question

Quizplus · Accepted Answer

Producing gas as a by-product of their activity is not a criteria for bacteria to be considered "probiotic." The other criteria are correct: they must be nonpathogenic when consumed, they must be able to survive transit through the digestive tract, and they must be able to alter the intestinal environment in a beneficial way. The statement "they must produce gas as a by-product of their activity" is not a criterion for bacteria to be considered probiotic. The other three criteria (nonpathogenic when consumed, able to survive transit through digestive tract, and able to alter the intestinal environment in a beneficial way) are all important for probiotic bacteria.
