There’s a bacterial enzyme called microbial transglutaminase that might help gut bacteria grow faster by changing the inside environment of the bacteria and making them use their energy to multiply instead of doing other things.

Assessment Explanation
The claim describes a specific biochemical mechanism (pH alteration → energy redirection → proliferation), which is plausible but highly complex and not yet demonstrated in published literature. No direct evidence links microbial transglutaminase to these precise intracellular effects in gut bacteria. The use of 'may promote' suggests uncertainty, but the phrasing implies a causal mechanism without qualifying it as hypothetical or speculative. The claim overstates certainty by presenting a multi-step mechanism as if established, when it remains a theoretical hypothesis. A more accurate phrasing would use probabilistic language.
More Accurate Statement
“Microbial transglutaminase may potentially influence intestinal bacterial growth by altering intracellular pH and redirecting energy, though this mechanism remains unproven.”

Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies
Supporting (1)
The study shows that a food additive called microbial transglutaminase makes gut bacteria grow more, which is exactly what the claim says — even if it doesn’t explain exactly how it happens.
