In the study, anaerobic digestion of residues from rose oil industry was investigated by using a laboratory scale completely mixed batch reactor in volume of 10 L and 4 small reactors in volume of 400 mL. Ten liters reactor isolated with a water jacket and 0.4 L reactors settled into a water bath were operated at 35 +/- 1 degrees C. The study supplies biochemical methane potential of hydrolyzed...

The production of pharmaceuticals, a multi-billion dollar worldwide industry, is expected to see large economic growth in the coming years. However, stagnation in the development of new products has led the industry to search for other methods to achieve these economic goals. The change from batch processing practices to the continuous production seen in commodity chemicals industries is a way ...

It is discussed how the automatic seeking of optimal steady states in biochemical reactors can be achieved by using non-model based extremum-seeking control with semi-global practical stability and convergence properties. A special attention is paid to processes with multiple steady-states and multivalued cost functions. Copyright c ©IFAC 2007

BACKGROUND A promising route to renewable liquid fuels and chemicals is the fermentation of synthesis gas (syngas) streams to synthesize desired products such as ethanol and 2,3-butanediol. While commercial development of syngas fermentation technology is underway, an unmet need is the development of integrated metabolic and transport models for industrially relevant syngas bubble column reacto...

Artificial Cells In article number 2202962, Yoon-Kyoung Cho and co-workers discuss the latest advances in cell membrane-engineered micro or nanoreactors that simulate biochemical compartments, signaling cascades, energy generation, growth, reproduction, adaptability. These reactors have potential to provide hybrid solutions for pharmaceutical drugs, biosensors, novel materials, microreactors.

Living cells maintain a steady state of biochemical reaction rates by exchanging energy and matter with the environment. These exchanges usually do not occur in in vitro systems, which consequently go to chemical equilibrium. This in turn has severely constrained the complexity of biological networks that can be implemented in vitro. We developed nanoliter-scale microfluidic reactors that excha...
