Claims (23)
1. Celledyrkningsfremgangsmåde til kontrol af mælkesyreproduktion til lave niveauer i en fed-batch-cellekultur omfattede: blanding af dyreceller og et medium for at danne en cellekultur; og tilføring af glucose på en begrænset vis til cellekulturen, hvor tilføring af glucose på en begrænset vis omfatter tilvejebringelse af glucose til cellekulturen ved en hastighed, som er en funktion af en forventet eller en præmodelleret glucoseforbrugshastighed af dyrecellerne dyrket i medium indeholdende et højt niveau af glucose, hvor funktionen er multiplikation af den forventede hastighed med en procentdel mindre end 100%, og hvor procentdelen er ikke mere end 45%, og hvor en pH-sensor anvendes til at monitorere cellekulturens pH, og i respons til en stigning over en forudbestemt pH-værdi, yderligere glucose tilføres på en begrænset vis til cellekulturen.
2. Fremgangsmåde ifølge krav 1, hvor procentdelen er mindst 33%.
3. Fremgangsmåde ifølge krav 1, hvor tilføring af glucose på en begrænset vis omfatter tilsætning af én eller flere bolusser af glucosetilførsel.
4. Fremgangsmåde ifølge krav 1, hvor tilføringen af glucose på en begrænset vis tilvejebringes uden feedback-kontrol-prøveudtagning i løbet af dyrkning.
5. Fremgangsmåde ifølge krav 1, hvor en sensor anvendes til at monitorere cellekoncentration i cellekulturen, og en cellekoncentrationssensor-afledt måling yderligere anvendes i beregning af hastigheden af tilføring af glucose på en begrænset vis til cellekulturen.
6. Fremgangsmåde ifølge krav 1, hvor den den yderligere glucose tilført på en begrænset vis omfatter én eller flere bolusser af glucosetilførsel.
7. Fremgangsmåde ifølge krav 1, hvor den forudbestemte pH-værdi er omtrent 7.
8. Fremgangsmåde ifølge krav 1, hvor en pH-sensor anvendes til at monito-rere cellekulturens pH, og i respons til en stigning over en forudbestemt pH-værdi, tilføring af glucose på en begrænset vis efterfølgende forsætter ved en ny hastighed, som er større end en umiddelbart foregående hastighed.
9. Fremgangsmåde ifølge krav 8, hvor den ny hastighed er større med mindst 15% over den umiddelbart foregående hastighed.
10. Fremgangsmåde ifølge krav 8, hvor den ny hastighed er større med ikke mere end 50% over den umiddelbart foregående hastighed.
11. Fremgangsmåde ifølge krav 8, hvor responset til en stigning over en forudbestemt pH-værdi yderligere omfatter tilsætning af én eller flere bolusser af glucosetilførsel til cellekulturen.
12. Fremgangsmåde ifølge krav 8, hvor den forudbestemte pH-værdi er omtrent 7.
13. Fremgangsmåde ifølge krav 1, hvor (i) en cellekoncentrationssensor anvendes til at monitorere cellekoncentration i cellekulturen uden prøveudtagning, og en cellekoncentrationssensor-afledt måling yderligere anvendes i beregning af hastigheden af tilføring af glucose på en begrænset vis til cellekulturen; (ii) en pH-sensor anvendes til at monitorere cellekulturens pH uden prøve-tagning, og i respons til en stigning over en forudbestemt pH-værdi, tilføring af glucose på en begrænset vis efterfølgende fortsætter ved en ny hastighed, som er større end en umiddelbart foregående hastighed; eller (iii) både cellekoncentrationssensoren og pH-sensoren anvendes som beskrevet i henholdsvis (i) og (ii).
14. Fremgangsmåde ifølge krav 13, hvor responset til en stigning over en forudbestemt pH-værdi i (ii) og/eller (iii) yderligere omfatter tilsætning af én eller flere bolusser af glucosetilførsel til cellekulturen.
15. Fremgangsmåde ifølge krav 13, hvor den forudbestemte pH-værdi er omtrent 7.
16. Fremgangsmåde ifølge krav 1, hvor den præmodellerede hastighed bestemmes ved blanding af dyreceller og et medium indeholdende et højt niveau af glucose for at danne en første cellekultur; og bestemmelse af en glu-coseforbrugshastighed for dyrecellerne dyrket i den første cellekultur.
17. Fremgangsmåde ifølge krav 16, hvor en pH-sensor anvendes til at moni-torere pH af den anden cellekultur, og i respons til en stigning over en forudbestemt pH-værdi, tilføring af glucose på en begrænset vis yderligere omfatter tilsætning af én eller flere bolusser af glucosetilførsel til den anden cellekultur.
18. Fremgangsmåde ifølge krav 17, hvor tilføring af glucose på en begrænset vis til den anden kultur yderligere omfatter efterfølgende fortsættelse af tilføring ved en ny hastighed, som er større end en umiddelbart foregående hastighed.

21. Fremgangsmåde ifølge krav 18, hvor den ny hastighed er større med ikke mere end 50% over den umiddelbart foregående hastighed.
22. Fremgangsmåde ifølge krav 1, hvor den præmodellerede hastighed bestemmes ved blanding af dyreceller og et medium indeholdende et højt niveau af glucose for at danne en første cellekultur; bestemmelse af en glucoseforbrugshastighed for dyrecellerne dyrket i den første cellekultur; blanding af dyreceller og et medium for at danne en anden cellekultur; og tilføring af glucose på en begrænset vis til den anden cellekultur ved en hastighed, som er en funktion af den bestemte glucoseforbrugshastighed; hvor (i) en cellekoncentrationssensor anvendes til at monitorere cellekoncentrationen i den anden cellekultur uden prøvetagning, og en cellekoncentrations-sensor-afledt måling yderligere anvendes i beregning af hastigheden af tilfø-ring af glucose på begrænset vis til den anden cellekultur; (ii) en pH-sensor anvendes til at monitorere pH af den anden cellekultur uden prøveudtagning, og i respons til en stigning over en forudbestemt pH-værdi, tilføring af glucose på en begrænset vis efterfølgende fortsætter ved en ny hastighed, som er større end en umiddelbart foregående hastighed; eller (iii) både cellekoncentrationssensoren og pH-sensoren anvendes som beskrevet i henholdsvis (i) og (ii).
23. Fremgangsmåde ifølge krav 22, hvor responset til en stigning over en forudbestemt pH-værdi i (ii) og/eller (iii) yderligere omfatter tilsætning af én eller flere bolusser af glucosetilførsel til den anden cellekultur.
