Results showed that the width of the myosepta (MS) was significantly increased, and nonanal, (E, Z)-2,6-nonadienal, octanal, 1-octen-3-ol, and hexanal emerged as the top five contributors to the overall odor profile of the fish fillets, following exposure to the high-lipid (HL) diet. Lipidomic profiling demonstrated that triglycerides (TG) were the predominated lipid class in both muscle fibers (MF) and MS fractions. The HL diet differentially modulated lipid composition: it upregulated TG content in MF, while reducing TG content and promoting the accumulation of phosphatidylcholine (PC) in MS. Gene expression analysis showed tissue-specific regulation of lipid metabolism. In MF, the upregulation of fatty acid binding protein 1 (<em>fabp1</em>) and perilipin-3 (<em>plin3</em>), and the downregulation of <em>fabp2</em>, peroxisome proliferator activated receptor α (<em>pparα</em>), <em>pparβ</em>, acyl-CoA oxidase (<em>acox</em>), and carnitine palmitoyltransferase 1 (<em>cpt1</em>), were induced by the HL diet, which collectively promoted TG synthesis and storage, which may be one of the underlying mechanisms contributing to the formation of a more intense odor profile in MF.

Whole-genome sequencing (WGS) is a widely used method to detect and characterize foodborne pathogens, but comparatively little research has focused on its application to GMMs. Here, we present a WGS-based bioinformatics workflow for the characterization of <em>B. subtilis</em> group and <em>B. cereus</em> group isolates, which includes a novel approach for the detection of known GMMs based on detecting known transgenic elements and host strains. The workflow supports both short-read (Illumina) and long-read (Oxford Nanopore Technologies) sequencing data and performs common genomic assays such as quality checks or taxonomic identification. Additionally, isolates are screened for genes associated with antimicrobial resistance, virulence genes and mobile genetic elements. The workflow largely follows the recent EFSA guidelines for WGS-based characterization of micro-organisms in the food chain. We demonstrate that the workflow correctly identifies known genetically modified <em>B. subtilis</em> strains, while not mislabeling wild-type strains as GMM. Finally, using publicly available datasets, we show that the workflow accurately characterizes and identifies subspecies for <em>B. cereus</em>. This automated solution for detecting known GMMs and foodborne pathogens within the <em>Bacillus</em> genus can support regulatory compliance and contribute to ensure food safety.</div></div>","PeriodicalId":34477,"journal":{"name":"Food Chemistry Molecular Sciences","volume":"12 ","pages":"Article 100338"},"PeriodicalIF":4.7,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145791488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
