WebIn such cases, fed-batch cultivation could be an alternative. Fed-batch combines part of the advantages of both batch and continuous cultivations. In fed-batch cultivation, there is no washout of biomass, and concentration of inhibitors in the media is kept low if in situ detoxification can occur. WebFed-batch culture is a modified batch culture method or an intermediate of batch and continuous fermentation techniques. Like batch culture, products of the fed-batch culture are harvested in batches, i.e. after the batch …
WebThe most commonly used intensified processes are operated using a perfusion or fed-batch seed bioreactor enabling a higher than usual seeding density in the fed-batch production bioreactor. Hence, as part of the growth phase is shifted to the seed bioreactor, there is a lower split ratio, which increases the criticality of the seed bioreactor ... WebMar 20, 2024 · All cultures were inoculated at a final density ranging from 0.30 to 0.45 × 10 6 cells/mL (with a target of 0.3 × 10 6 cells/mL). We cultivated cells initially at 37 °C. In the batch run, we held that temperature constant.
