However, very little effort has been expended at scaling up this process for the extraction of real fermentation broth. When real broths are used with reverse micellar phases there are major problems with emulsion formation. In this study the effect of a variety of demulsifiers on lysozyme extraction was evaluated in terms of their influence on the separating properties of the emulsion, water content (Wo), and, extraction yield and kinetics from both buffer and hen egg white. In addition, the use of a low shear contactor (a Graesser or 'raining bucket') was assessed in terms of its suitability as a RM contactor. It was found that most of the demulsifiers reduced the settling time of the emulsion, and enhanced the yield and kinetics of lysozyme extraction from hen egg white. It was hypothesised that this was due to the demulsifier displacing the lysozyme from the interface and preventing the protein unfolding and precipitating. This effect was found to depend on both the generic type of demulsifier, and its concentration.</p>","PeriodicalId":9179,"journal":{"name":"Bioseparation","volume":"9 2","pages":"81-91"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1023/a:1008183828223","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21734411","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}
