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.
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 ...
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 ...
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. ...
Protein extraction using the sodium bis(2-ethylhexyl) phosphate (NaDEHP) reverse micellar system
(Wiley Subscription Services, Inc., A Wiley Company, 1996-04-20)
The reverse micellar system of sodium bis(2-ethylhexyl) phosphate (NaDEHP)/isooctane/brine was used for liquid-liquid extraction of proteins. We investigated the solubilization of cytochrome-c and Α-chymotrypsin into the ...
Computer aided analysis for biosensing and screening
(Wiley Subscription Services, Inc., A Wiley Company, 1988-02-20)
Biosensors with animal and microbial cells immobilized close to the tip of a membrane electrode have been developed for chemical and drug testing. Our experimental results show that biosensors can be used for drug screening ...
Degradation kinetics of pentachlorophenol by Phanerochaete chrysosporium
(Wiley Subscription Services, Inc., A Wiley Company, 1990-05)
The extracellular enzymes and cell mass from the pregrown Phanerochaete chrysosporium cultures were used for the degradation of PCP. The use of both extracellular enzymes and cell mass resulted in extensive mineralization ...
