Hypothesis
Air/O2-saturated liquid PFCs can enhance the cell density and eventually production of recombinant proteins in small-scale high cell density cultivations.
Conclusion
The study confirmed that perfluorinated oxygen carriers can enhance the growth of E. coli and increase the yield of recombinant proteins in miniaturized fed-batch cultures.
Supporting Evidence
- PFD addition improved cell density by 40% compared to control cultures.
- The highest cell density was achieved with PFD enriched with 40% v/v of pure oxygen.
- The volumetric yield of soluble ADH increased with higher cell densities.
Takeaway
Adding a special liquid that carries oxygen helps E. coli grow better and make more proteins, especially when added at the right time.
Methodology
The study used miniaturized fed-batch cultures in 24-deep well plates to evaluate the effects of perfluorodecalin on E. coli growth and protein production.
Limitations
The application of PFCs is limited by their relatively high cost and the timing of their addition during cultivation.
