TL;DR: Flow cytometric analysis revealed reduced damage with respect to cytoplasmic membrane potential and integrity in cells grown in the dynamic environments of the large scale reactor and the scale-down reactor.
Journal ArticleDOI
Technologies for butanol recovery integrated with fermentations
TL;DR: In this article, five technologies for in-situ product recovery have been compared on the basis of design parameters and energy efficiency: stripping, adsorption, liquid-liquid extraction, pervaporation and membrane solvent extraction.
Journal ArticleDOI
Effect of agitation intensities on fungal morphology of submerged fermentation.
TL;DR: It was found that the porosity of pellets showed an inverse relationship with the specific energy dissipation rate and that the dry biomass per-wet-pellet volume increased with the Specific Energy dissipation rates.
Journal ArticleDOI
A simple hydrodynamic model for the liquid circulation velocity in a full-scale two- and three-phase internal airlift reactor operating in the gas recirculation regime
J. J. Heijnen,J. Hols,R. G. J. M. van der Lans,H. L. J. M. van Leeuwen,Arnold Mulder,Rene Weltevrede +5 more
TL;DR: In this article, a simple model to predict the hydrodynamic behavior of a three-phase internal air-lifted reactor is developed, which predicts liquid circulation, gas hold-up and minimum gas supply rates for solids suspension.
Journal ArticleDOI
Butanol recovery from fermentations by liquid-liquid extraction and membrane solvent extraction
W. J. Groot,H. S. Soedjak,P. B. Donck,R. G. J. M. van der Lans,K. Ch. A. M. Luyben,J. M. K. Timmer +5 more
TL;DR: In this paper, the authors evaluated the applicability of liquid-liquid extraction and membrane solvent extraction in butanol fermentations to increase the substrate conversion and found that a threefold increase in the substrate consumption could be achieved, in the continuous fermentation about 30% increase.
