In this study, 16S rRNA gene and ITS amplicon sequencing were used to characterize the bacterial and fungal communities on intact and mechanically damaged H. marmoreus during 15 days of storage at 4 \u00b0C. Storage time, rather than mechanical damage, was the main driver of whole-community variation, although mechanical damage accelerated visible spoilage assessed qualitatively. Bacterial communities showed pronounced temporal turnover, shifting from early Firmicutes-rich assemblages to late-stage Proteobacteria-dominated communities, especially Pseudomonas. In contrast, fungal communities remained largely dominated by Ascomycota throughout storage, although mechanically damaged mushrooms showed a greater late-stage occurrence of opportunistic yeasts such as Candida. Predicted functional and phenotypic analyses further suggested late-stage increases in Gram-negative, aerobic, biofilm-forming, stress-tolerant, and potentially pathogenic bacterial traits. Because these traits were inferred from 16S rRNA gene-based prediction rather than measured directly, they should be interpreted cautiously. Overall, the results suggest that maintaining the physical integrity of H. marmoreus during postharvest handling may help preserve quality and delay the emergence of spoilage-associated microbial traits during refrigerated storage.<\/jats:p>","DOI":"10.3390\/microorganisms14040762","type":"journal-article","created":{"date-parts":[[2026,3,27]],"date-time":"2026-03-27T14:33:33Z","timestamp":1774622013000},"page":"762","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Mechanical Damage Modulates Bacterial and Fungal Succession on the Surface of Hypsizygus marmoreus During Refrigerated Storage"],"prefix":"10.3390","volume":"14","author":[{"given":"Jingming","family":"Ma","sequence":"first","affiliation":[{"name":"Haide College, Ocean University of China, Qingdao 266100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingzheng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Marine Science Research Institute of Shandong Province, Qingdao 266104, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qian","family":"Liu","sequence":"additional","affiliation":[{"name":"Marine Science Research Institute of Shandong Province, Qingdao 266104, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8006-7162","authenticated-orcid":false,"given":"Xiuling","family":"Wang","sequence":"additional","affiliation":[{"name":"National Engineering Research Center of Edible Fungi, Key Laboratory of Agricultural Genetics and Breeding of Shanghai, Institute of Edible Fungi, Shanghai Academy of Agricultural Sciences, Shanghai 201403, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Angelini, P., Flores, G.A., Cusumano, G., Venanzoni, R., Pellegrino, R.M., Zengin, G., Di Simone, S.C., Menghini, L., and Ferrante, C.
