MUC5AC and metabolic dysfunction-associated steatotic liver disease: Accordingly, Anaerotruncus are identified as butyrate-producing mucin degraders,72,73 CAG-95 are predicted butyrate producers that strongly correlate with host health,74Kineothrix are butyrate producers shown to positively impact the gut by attenuating metabolic dysfunction-associated steatotic liver disease (MASLD),75,76 and Lawsonibacter also demonstrate butyrate production and, intriguingly, strongly associate with coffee consumption.77,78
