Furthermore, the optimal operating regime was identified to be continuous fermentation process with gas stripping, in which a high ethanol productivity of 113 mmol L−1 h−1, i.e., 26.8 mmol C (g DCW −1 h−1, corresponding to 90.2% of the maximum theoretical ethanol yield could be achieved.
Continuous fermentation, agitation, mass transfer, and scale-up in fermentation systems, enzyme technology.
"This is our continuous fermentation line," Mr. Alexander said proudly.
In a continuous fermentation, significant advantages may be gained by immobilization of microbial cells.
Itaconic acid (IA) can be produced by fermentation and continuous fermentation with continuous product removal is highly desired.
Moreover, attaching G. sulfurreducens on a carbon material could allow its use during continuous fermentation, thus overcoming the growth limitations observed during batch operations.
Larger boxes are used in trough fermentation, and in continuous fermentation the leaf is spread on trays on a conveyor system.
For the study of the continuous fermentation in a loop bioreactor, the entrapment and the activity of cells into a Ca-alginate matrix and the solvent extractive fermentation were considered.
In addition, there are also many strategies to improve fermentation technology, such as multi-stage continuous fermentation, continuous fermentation integrated with immobilization and cell recycling, and the inclusion of additional organic acids or electron carriers to change metabolic flux.
Continuous fermentation set-ups are of great interest for studying the physiology of microorganisms.
