Mixing and mass transfer in a pilot scale U‐loop bioreactor

02-Sep-2016 | Leander A.H. Petersen, John Villadsen, Sten B. Jørgensen, Krist V. Gernaey, Biotechnology and Bioengineering, 2016

ABSTRACT A system capable of handling a large volumetric gas fraction while providing a high gas to liquid mass transfer is a necessity if the metanotrophic bacterium Methylococcus capsulatus is to be used in single cell protein (SCP) production. In this study, mixing time and mass transfer ...

Physicothermal Properties of Aqueous Sodium Chloride Solutions

03-Nov-2014 | G.R. Carvalho, F. Chenlo, R. Moreira, J. Telis‐Romero, Journal of Food Process Engineering, 2014

Abstract Physicothermal properties of sodium chloride solutions as complementary information to the existent in literature were experimentally measured under different conditions of mass concentration (in the range of 0.040 kg NaCl/kg solution to 0.240 kg NaCl/kg solution) and temperature ...

Non‐Newtonian Fluid Mixing in a Twin‐Screw Mixer Geometry: Three‐Dimensional Mesh Development, Effect of Fluid Model and Operating Conditions

03-Nov-2014 | Maureen L. Rathod, Bharani K. Ashokan, Lindsay M. Fanning, Jozef L. Kokini, Journal of Food Process Engineering, 2014

Abstract Mixing was examined in a Readco continuous mixer (Readco Kurimoto, LLC, York, PA); a mesh was developed for three‐dimensional (3D) finite element method simulation and validated against experimental Newtonian fluid results. The mesh was designed to ensure accuracy in areas with a ...

Advances in turbulent mixing techniques to study microsecond protein folding reactions

19-Jul-2013 | Sagar V. Kathuria, Alexander Chan, Rita Graceffa, R. Paul Nobrega, C. Robert Matthews, Thomas C. Irving, Blair Perot ..., Biopolymers, 2013

Abstract Recent experimental and computational advances in the protein folding arena have shown that the readout of the one‐dimensional sequence information into three‐dimensional structure begins within the first few microseconds of folding. The initiation of refolding reactions has been ...

Bioactive polyacrylamide hydrogels with gradients in mechanical stiffness

14-Dec-2012 | Vincent E.G. Diederich, Peter Studer, Anita Kern, Marco Lattuada, Giuseppe Storti, Ram I. Sharma, Jess G. Snedeker, ..., Biotechnology and Bioengineering, 2012

Abstract We propose a novel, single step method for the production of polyacrylamide hydrogels with a gradient in mechanical properties. In contrast to already existing techniques such as UV photo‐polymerization with photomasks (limited penetration depth) or microfluidic gradient mixers ...

Considering water availability and the effect of solute concentration on high solids saccharification of lignocellulosic biomass

22-Aug-2012 | Michael J Selig, Chia‐wen Carmen Hsieh, Lisbeth G Thygesen, Michael E Himmel, Claus Felby, Stephen R Decker, Biotechnology Progress, 2012

Abstract Milliliter scale (ligno)cellulose saccharifications suggest general solute concentration and its impact on water availability plays a significant role in detrimental effects associated with high solids lignocellulose conversions. A microtumbler developed to enable free‐fall mixing at ...

The Stokes Number Approach to Support Scale-Up and Technology Transfer of a Mixing Process

26-Jun-2012 | Tofan A. Willemsz, Ricardo Hooijmaijers, Carina M. Rubingh, Henderik W. Frijlink, Herman Vromans, Kees van der Voort ..., AAPS PharmSciTech, 2012

Transferring processes between different scales and types of mixers is a common operation in industry. Challenges within this operation include the existence of considerable differences in blending conditions between mixer scales and types. Obtaining the correct blending conditions is crucial for ...

Study of hydrodynamic characteristics in tubular photobioreactors

23-Jun-2012 | Qinghua Zhang, Xia Wu, Shengzhang Xue, Kehong Liang, Wei Cong, Bioprocess and Biosystems Engineering, 2012

In this work, the hydrodynamic characteristics in tubular photobioreactors with a series of helical static mixers built-in were numerically investigated using computational fluid dynamics (CFD). The influences of height and screw pitch of the helical static mixer and fluid inlet velocity on the ...
