A novel multidisciplinary approach combining gravimetric assays, metagenomic sequencing, and scanning electron microscopy (SEM) was applied to characterise both microbial composition and degradation dynamics. Dominant genera such as Bacillus, Microbacterium, and Acinetobacter were associated with collagen degradation and metal tolerance, with Bacillus-rich communities showing the most pronounced mass loss (up to 3%). SEM analysis revealed the formation of robust biofilms and extensive matrix disruption, indicating enzymatic activity and structural breakdown of the leather. The formation of exopolysaccharide-rich biofilms was found to be critical for microbial adhesion and biodegradation efficacy. These findings provide initial insights into microbial mechanisms involved in the degradation of chromium-tanned leather and suggest potential applications for microbial consortia in future sustainable leather waste management strategies.","PeriodicalId":163,"journal":{"name":"Environmental Microbiology Reports","volume":"17 3","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1758-2229.70134","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although they are the second most abundant coral group on tropical reefs and contribute significantly to the structural complexity of Mediterranean coral reefs, their microbial dynamics are largely unexplored. In this study, we investigated the acquisition of the bacterial microbiota in the red coral Corallium rubrum, a precious coral. By analysing the composition of the bacterial community at different early life stages, including newly released larvae, 5- and 10-day-old larvae, 3-month-old settlers, 1-year-old recruits and 3-year-old juveniles, we are gaining new insights into the development of its microbiome. Using a direct PCR-based 16S rRNA metabarcoding approach, we performed high-resolution microbiome analyses at the level of individual larvae and settlers. Our results show that the bacterial microbiota of C. rubrum matures after the first year of life. Notably, dominant symbionts, such as Spirochaetaceae and BD72BR169 Gammaproteobacteria, were absent in larvae, settlers and recruits, suggesting that they were likely acquired horizontally from the environment. These findings improve our understanding of the microbial colonisation and development of C. rubrum and shed light on the potential role of its bacterial community in holobiont function.","PeriodicalId":163,"journal":{"name":"Environmental Microbiology Reports","volume":"17 3","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1758-2229.70127","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
