Here, we assessed the anti-Candida effect of cell-free supernatants (CFSs) from three different fecal isolates and one ATCC strain of S. cerevisiae. We evaluated C. albicans growth inhibition through CFUs, and the impairment of virulence factors (adhesion, biofilm formation, and metabolic activity) by crystal violet and XTT assays. An untargeted metabolomic analysis of the CFSs was also performed. The CFSs moderately reduced C. albicans growth, but they could impair C. albicans virulence by reducing its capacity to adhere and to form a biofilm, and by decreasing the metabolic activity of biofilm-embedded fungal cells. The untargeted metabolomic analysis indicated an overexpression of N-acetyl-DL-tryptophan and other molecules derived from its metabolism (kynurenic acid and indole-3-acrylic acid), the dipeptides glycyl-L-leucine, prolyl-leucine, and \u03b3-L-glutamyl-L-leucine, and the unconventional nucleotide inosine in the CFSs from fecal isolates, as compared to the reference strain. Further studies are warranted to better characterize the metabolome of these CFSs. Should the effects described here also be confirmed in vivo, the possible future employment of S. cerevisiae CFSs as a postbiotic aid to the current antifungal therapy may be considered.<\/jats:p>","DOI":"10.3390\/jof12020081","type":"journal-article","created":{"date-parts":[[2026,1,26]],"date-time":"2026-01-26T16:13:48Z","timestamp":1769444028000},"page":"81","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Untargeted Metabolomic Analysis of Cell-Free Supernatants (CFSs) from Different Clinical Isolates of Saccharomyces cerevisiae and Their Effects on Candida albicans Virulence"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1369-0955","authenticated-orcid":false,"given":"Luca","family":"Spaggiari","sequence":"first","affiliation":[{"name":"Department of Surgical, Medical, Dental and Morphological Sciences with Interest in Transplant, Oncological and Regenerative Medicine, University of Modena and Reggio Emilia, 41124 Modena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriele","family":"Tedeschi","sequence":"additional","affiliation":[{"name":"Department of Life Sciences, University of Modena and Reggio Emilia, 41125 Modena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giulia","family":"Benatti","sequence":"additional","affiliation":[{"name":"Department of Life Sciences, University of Modena and Reggio Emilia, 41125 Modena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"De Benedittis","sequence":"additional","affiliation":[{"name":"Department of Life Sciences, University of Modena and Reggio Emilia, 41125 Modena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Teresa","family":"Franz\u00e8","sequence":"additional","affiliation":[{"name":"Department of Surgical, Medical, Dental and Morphological Sciences with Interest in Transplant, Oncological and Regenerative Medicine, University of Modena and Reggio Emilia, 41124 Modena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diego","family":"Pinetti","sequence":"additional","affiliation":[{"name":"Centro Interdipartimentale Grandi Strumenti (C.I.G.S.), University of Modena and Reggio Emilia, 41125 Modena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5299-8197","authenticated-orcid":false,"given":"Eva","family":"Pericolini","sequence":"additional","affiliation":[{"name":"Department of Surgical, Medical, Dental and Morphological Sciences with Interest in Transplant, Oncological and Regenerative Medicine, University of Modena and Reggio Emilia, 41124 Modena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9845-7399","authenticated-orcid":false,"given":"Andrea","family":"Ardizzoni","sequence":"additional","affiliation":[{"name":"Department of Surgical, Medical, Dental and Morphological Sciences with Interest in Transplant, Oncological and Regenerative Medicine, University of Modena and Reggio Emilia, 41124 Modena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,23]]},"reference":[{"key":"ref_1","unstructured":"Money, N.P.
