Ruminococcaceae is a family of obligate anaerobic, Gram-positive bacteria in the order Clostridiales (phylum Firmicutes) that represents one of the most important Butyrate-producing and fiber-degrading families in the human gut. Key genera include Faecalibacterium (including Faecalibacterium prausnitzii), Ruminococcus, Subdoligranulum, Oscillibacter, and Anaerotruncus.

Schizophrenia: Ruminococcaceae depletion correlates with negative symptoms and poorer functioning; FEP patients show the most pronounced loss.
MS: Depleted in MS patients; diet-responsive (Mediterranean diet enriches Ruminococcaceae).
Diet-responsive: Fiber-rich and Mediterranean diets selectively enrich Ruminococcaceae.

Ruminococcaceae depletion is among the most consistent microbiome findings across disease states—paralleling and overlapping with Lachnospiraceae depletion.

Functional Significance#
Ruminococcaceae's depletion removes. butyrate—colonocyte fuel, HDAC inhibitor, tight junction and epithelial-barrier protector, Treg inducer. Fiber degradation—cellulose, xylan, and resistant starch breakdown (Saccharolytic Fermentation). Cross-Feeding—acetate→butyrate conversion for downstream SCFA production.
Colonization resistance—niche occupation preventing pathobiont expansion.
Metal Connection#
Butyrate production by Ruminococcaceae depends on iron-sulfur cluster enzymes (butyryl-CoA dehydrogenase). Heavy metal disruption of iron homeostasis impairs the family's core metabolic function.
