Understanding the interrelationships between the differentially abundant microorganisms and metabolites of traditional “Fuet” fermented sausages (FSs) and inoculated fermented sausages (IFSs) can help us identify key species that are missing from commercial starter cultures to reproduce the flavor compounds and nutrients of traditional Fuet FSs. IFSs, inoculated with P. pentosaceus , P. acidilactici , S. xylosus , S. carnosus (SBM-52) or P. pentosaceus , and S. xylosus (THM-17), were deficient in reproducing the volatilome profile (in particular esters, methyl aldehydes, and methyl ketones) of traditional Fuet FSs because of the lack of diverse Staphylococci ( S. carnosus , S. xylosus , S. equorum , and S. saprophyticus ). Moreover, the combination of Pediococcus and Staphylococcus were positively associated with amino acid, fatty acid, l -anserine, and l -carnosine levels. Pyridoxal and indolelactic acid levels were significantly increased in IFSs with the addition of P. acidilactici and S. carnosus , which were positively associated with vitamin B 6 and tryptophan metabolic pathways.
