Desorption by ultrasound: Phenol on activated carbon and polymeric resin
(Wiley Subscription Services, Inc., A Wiley Company, 1998-07)
An experimental feasibility study of using ultrasound to accomplish the dificult desorption of phenol from activated carbon and polymeric resin adsorbents is discussed. The desorption rates of activated carbon were found ...
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 ...
The effects of exopolymers on cell morphology and culturability of Leuconostoc mesenteroides during starvation
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-11)
Biofilm formation by bacterial cells can be used to modify the subsurface permeability for the purpose of microbial enhanced oil recovery, bio-barrier formation, and in situ bioremediation. Once injected into the subsurface, ...
Recuperative parametric pumping in adsorptive membranes
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1996-01)
Recuperative parametric pumping in adsorptive membranes, a cyclical adsorptive separation process, can lead to two distinct mechanisms of separation: rejection and preferential transport. During rejection, the adsorptive ...
Kinetics and fractal properties of the random sequential adsorption of line segments
(IOP Publishing Ltd, 1990-11-07)
The random sequential adsorption (RSA) of infinitely-thin line segments is studied by computer simulation. It is shown that the exponent for the time dependence of the surface coverage increases beyond the value 0.33, ...

Quantitative evaluation of the pH profile in organic acid fermentations
(Wiley Subscription Services, Inc., A Wiley Company, 1991-01-20)
No Abstrct.
Recovery of a foreign protein from the periplasm of Escherichia coli by chemical permeabilization
(Elsevier, 1990-08)
We have applied the technique of protein release by chemical permeabilization to recover a foreign protein in active form from the periplasm of a recombinant strain of Escherichia coli. The two agents used in our chemical ...
Extraction of aminoglycoside antibiotics with reverse micelles
(John Wiley & Sons, Ltd., 1996-01)
The reverse micelle system of sodium di-2-ethylhexyl phosphate was used to extract aminoglycoside antibiotics, neomycin and gentamicin. The aminoglycosides can be efficiently extracted into a reverse micelle solution, and ...
Kinetics of silica particle formation in nonionic W/O microemulsions from TEOS
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1996-11)
The kinetics of silica particle formation by the ammonia-catalyzed hydrolysis of tetraethyl orthosilicate (TEOS) in water-in-oil (W/O) microemulsions containing a nonionic surfactant was investigated using Fourier-transform ...
