One of these is centrifugation, which serves to concentrate the inclusion bodies after disruption of the host microorganism, and also separates the inclusion bodies from other cellular debris. Monitoring the performance of the centrifuge is essential if excessive product and hence financial loss is to be avoided and a reasonable separation obtained. The analytical disc centrifuge may be used to monitor the centrifugation. This instrument returns the sample size distribution with high resolution and without fouling. By obtaining size distributions of the centrifuge feed, supernatant and concentrate, the fractional collection efficiency of the centrifuge may be determined as a function of the Stokes diameter, and a mass balance constructed.</p>","PeriodicalId":77022,"journal":{"name":"Australian journal of biotechnology","volume":"5 2","pages":"87-9"},"PeriodicalIF":0.0,"publicationDate":"1991-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12539250","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}

The capacity of biotechnology to manipulate and transform genetic material at a far greater rate than nature is capable of suggests that careful consideration should be given to effectively controlling these technologies. This paper examines the underlying technical and philosophical concerns and arguments which underpin the development of appropriate regulations for biotechnology. The regulatory frameworks which have been set in place around the world are reviewed. Modifications which are being introduced in the light of increasing practical experience and in response to changing societal pressures are discussed. Potential negative impacts of biotechnology on developing countries are specifically addressed. A case is made for co-ordinated international efforts to develop consistent and uniform legislation for the safe and environmentally beneficial application of biotechnology on a more equitable global basis.</p>","PeriodicalId":77022,"journal":{"name":"Australian journal of biotechnology","volume":"5 1","pages":"25-9, 47"},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12540986","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}
