The invention is intended to solve the technical problem that Clostridium capable of producing both short-chain fatty acids and 4-methylphenol are not present yet. The technical problem to be solved herein is to provide Clostridium fermenticellae, which can metabolize to produce short-chain fatty acids and 4-methylphenol. The Clostridium fermenticellae is collected under CGMCC 17037, is subjectedto fermenting culture under anaerobic conditions, has different medium components, and has different main metabolites; when sodium acetate and ethyl alcohol are added to a culture medium, the main products are short-chain fatty acids; when L-tyrosine is added, the main product is 4-methylphenol. The Clostridium fermenticellae is well worthy of application in terms of fermenting production of short-chain fatty acids and other baijiu-flavored matters, production of 4-methylphenol and the like.
