Freshly caught shrimp were processed on board the fishing vessel under the best possible hygienic conditions (IDEAL), unpeeled and manually (sterile) peeled, then stored on ice and at 7.5°C until microbiologically spoiled. Results were compared with industrially processed (INDUSTRIAL) shrimp. Isolates grown on various media were identified by 16S rRNA and gyr B gene sequencing. We examined the total microbiota and microbiological population shifts of shrimp under various storage conditions using denaturant gradient gel electrophoresis (PCR-DGGE). The microbiota differed somewhat during storage and among the various storage conditions; however, members of the genera <i>Psychrobacter</i> and <i>Pseudoalteromonas</i> were found to dominate the microbiota of all shrimp samples regardless of processing procedures or storage conditions. Most isolates could be identified by gyr B gene sequencing as <i>Psychrobacter immobilis</i> or <i>Psychrobacter cibarius</i>. Also <i>Pseudoalteromonas nigrifaciens, Pseudoalteromonas elyakovii</i> or <i>Pseudoalteromonas paragorgicola</i> dominated the microbiota of brown shrimp during storage. Also species from the genera <i>Planocuccus, Exiguobacterium, Carnobacterium, Pseudomonas, Chryseobacterium</i> and <i>Staphylococcus</i> were detected during storage of brown shrimp. Culture-dependent and culture-independent PCR-DGGE analysis produced different results in band patterns. Both methods are therefore required to accurately identify the microbiota and bacterial population shifts on seafood during storage.","AbstractOtherLang":null,"BibLvlCode":"AM","StandardTitle":"Molecular identification of the microbiota of peeled and unpeeled brown shrimp (<i>Crangon crangon</i>) during storage on ice and at 7.5°c","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2012,"MonPub":null,"DateUpdate":"2012-02-03","DateCreate":"2012-02-03","SecASFANote":null,"ConfID":null,"PeerRev":null,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":212562,"PubliDate":2012,"Pagination":"47-76","XtraPublOfAnaID":null,"ISBN":"978-90-5989-499-0","Volume":null,"Issue":null,"BRefMon":212523,"BRefMonRR":"<b>Broekaert, K.</b> (2012).
