Rapid protein release from Escherichia coli by chemical permeabilization under fermentation conditions
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-25)
Overall protein release greater than 75% in less than 1 h can be attained by exposing exponentially growing Escherichia coli cells to 0.4 M guanidine plus 0.5% Triton X-100 at 37°C in medium. Cell growth stops immediately ...
Quantitative evaluation of the pH profile in organic acid fermentations
(Wiley Subscription Services, Inc., A Wiley Company, 1991-01-20)
No Abstrct.
Stability of coextrusion through converging dies
(Elsevier, 1991-12)
A linear stability analysis of multilayer flow of viscoelastic liquids through long, converging dies is performed by a rigorous two-dimensional analysis (2-D), as well as by a simplified one-dimensional analysis (1-D) on ...
Selective extraction using preferential transport through adsorptive membranes
(Wiley Subscription Services, Inc., A Wiley Company, 1996-12-05)
Selective extraction of a protein from a mixture can be accomplished using an adsorptive membrane and low displacement recuperative parametric pumping. Low displacement recuperative parametric pumping can lead to the ...
Three-dimensional streamlined finite elements: Design of extrusion dies
(John Wiley & Sons, Ltd, 1992-01-15)
A method to determine three-dimensional die shapes from extrudate swell and vice versa is presented using a three-dimensional Galerkin finite element method based on a streamlined formulation with the fluid velocities and ...
Cell affinity separations using magnetically stabilized fluidized beds: Erythrocyte subpopulation fractionation utilizing a lectin-magnetite support
(Wiley Subscription Services, Inc., A Wiley Company, 2003-03-20)
A magnetically stabilized fluidized bed is used to separate erythrocyte subpopulations. Binding specificity was obtained by immobilizing the lectin Helix pomatia Agglutinin (HpA) or Griffonia simplicifolia I (GSI) onto ...
Pore-scale investigation of biomass plug development and propagation in porous media
(John Wiley & Sons, Inc., 2002-03-05)
Biomass plugging of porous media finds application in enhanced oil recovery and bioremediation. An understanding of biomass plugging of porous media was sought by using a porous glass micromodel through which biomass and ...
Growth of Leuconostoc mesenteroides NRRL-B523 in an alkaline medium: Suboptimal pH growth inhibition of a lactic acid bacterium
(Wiley Subscription Services, Inc., A Wiley Company, 2005-01-05)
Bacterial profile modification (BPM), a form of tertiary oil recovery, diverts water from the water-flooded high-permeability zone into the oil-bearing low-permeability zone. During field use, exopolymer-producing bacteria ...
A Stochastic Model for Wound Healing
(Kluwer Academic Publishers-Plenum Publishers; Springer Science+Business Media, Inc., 2006-03)
We present a discrete stochastic model which represents many of the salient features of the biological process of wound healing. The model describes fronts of cells invading a wound. We have numerical results in one and ...
Biomass evolution in porous media and its effects on permeability under starvation conditions
(John Wiley & Sons, Inc., 2000-07-05)
The purpose of this study was to understand bacteria profile modification and its applications in subsurface biological operations such as biobarrier formation, in situ bioremediation, and microbial-enhanced oil recovery. ...
