Disturbing increase of pesticids and other pollutants which attain the Waddensea via the river Rhine stirred us to make several researches. <i>Desulfovibrio</i>, a very general representant of the Waddensea, was made an example for these researches because of her interesting metabolitical qualities, likewise its short generation time. In spite of the imperfect methode of these experiments, we can by means of the continuous culture explain more about the influence of a pollutant upon the growth of an organism than it would have been possible in case of a batch-culture. During the experiment a division has been made between a) the influence upon exponential growth-rate, b) the influence upon metabolism. In the first case culture will wash out, in the other case there will be question of a smaller growth result. At the same time experiments have been done with pollutants in a batch-culture, as well with gathered cells.","AbstractOtherLang":"Onderzocht is of met de kontinue kultuur de toxiciteit van bepaalde stoffen op een <i>Desulfovibrio</i> kultuur exact bepaald kan worden. Dit is gebeurd vanwege de verontrustende stijging van pesticides en andere toxische stoffen, die via de Rijn de Waddenzee bereiken. <i>Desulfovibrio</i>, die als zeer algemeen voorkomende bacterie in de Waddenzeebodem voorkomt, is vanwege haar interessante metabolische eigenschappen alswel vanwege haar korte generatietijd als voorbeeld genomen. Het resultaat van dit onderzoek is, dat, ondanks vele gebreken aan de methode, met behulp van een kontinue kultuur meer gezegd kan worden over de wijze waarop een toxische stof de groei van een organisme beinvloedt dan met behulp van een gesloten kultuur, Tijdens de proef is er een scheiding gemaakt tussen een beïnvloeding enerzijds van de specifieke groeisnelheidsconstante, anderzijds van het metabolisme. In het eerste geval zal de kultuur ui tspoelen, in het laatste geval zal er sprake zijn van een kleinere groeiopbrengst. Tevens zijn parallel aan deze proef experimenten verricht met toxische stoffen in een gesloten kultuur en met geoogste cellen.","BibLvlCode":"MS","StandardTitle":"De chemostaat als middel om de toxiciteit van giftige stoffen op een <i>Desulfovibrio</i> kultuur te bepalen","OrigTitleLangCode":"nl","OrigTitleLangCodeExtended":"dut","OrigTitleLangID":41,"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":null,"MonPub":1974,"DateUpdate":"2019-08-14","DateCreate":"2001-07-09","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":null,"monrec":{"MonID":13058,"ISBN":null,"PubliDate":1974,"IssueDate":null,"Volume":"1974","Issue":"8","Pagination":"33","Place":"Texel","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":5697,"SerRR":"NIOZ-rapport.
