Use of coimmobilized biological systems to degrade toxic organic compounds
(Wiley Subscription Services, Inc., A Wiley Company, 1991-07)
The concept of coimmobilizing cell mass (and/or enzyme) and adsorbent in a hydrogel matrix for biodegradation of toxic organic chemicals was introduced. Under defined experimental conditions, the coimmobilized system using ...
Effect of adsorbents on degradation of toxic organic compounds by coimmobilized systems
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-15)
The use of coimmobilized systems for treatment of toxic organic compounds has been proposed. The proposed approach combines the use of adsorbents and laboratory identified microorganisms immobilized in a protective permeable ...
Esterification reactions of lipase in reverse micelles
(Wiley Subscription Services, Inc., A Wiley Company, 1990-04-05)
The activities of lipase from Candida cylindracea and Rhizopus delemar have been investigated in water/AOT/iso-octane reverse micellar media through the use of two esterification reactions: fatty acid-alcohol esterification ...
A new isolation and purification method for staphylococcal protein A using membrane encapsulated rabbit IgG-agarose
(Wiley Subscription Services, Inc., A Wiley Company, 1989-10-20)
A new isolation and purification method for bioproducts using membrane-encapsulated affinity adsorbents was investigated. The new method involves encapsulation of affinity adsorbents, batch adsorption of the bioproduct ...
Protein release from Escherichia coli cells permeabilized with guanidine–HCl and Triton X100
(Wiley Subscription Services, Inc., A Wiley Company, 1989-02-20)
An important factor complicating the recovery of recombinant proteins from Escherichia coli is their intracellular location. An alternative to the commonly used method of releasing these proteins by mechanical disruption ...
Model-based analysis and design of a microchannel reactor for tissue engineering
(Wiley Subscription Services, Inc., A Wiley Company, 2006-06-20)
Recently developed perfusion micro-bioreactors offer the promise of more physiologic in vitro systems for tissue engineering. Successful application of such bioreactors will require a method to characterize the bioreactor ...
Domestic Violence and Women’s Employment: Fixed Effects Models of Three Waves of Women’s Employment Study Data
(Kluwer Academic Publishers-Plenum Publishers; Springer Science + Business Media, Inc., 2005-09)
Domestic violence can interfere with women’s ability to work, and may result in loss of welfare benefits and poorer economic outcomes. Previous studies showing no effect of domestic violence on employment could be a result ...
Interaction of infectious viral particles with a quaternary ammonium chlorid (QAC) surface
(Wiley Subscription Services, Inc., A Wiley Company, 1989-08-20)
The antiviral activity of a surface-bonded quaternary ammonium chloride (QAC) was examined in this study. The mechanism of inactivation was elucidated by a combination of infectivity assay, radioactive labeling assay, and ...
Leuconostoc mesenteroides growth kinetics with application to bacterial profile modification
(Wiley Subscription Services, Inc., A Wiley Company, 1994-04-15)
Bacterial profile modification (BPM) is being developed as an oil recovery technique that uses bacteria to selectively plug oil depleted zones within a reservoir to divert displacing fluids (typically water) into oil-rich ...
Biomass plug development and propagation in porous media
(John Wiley & Sons, Inc., 2001-02-05)
Exopolymer-producing bacteria can be used to modify soil profiles for enhanced oil recovery or bioremediation. Understanding the mechanisms associated with biomass plug development and propagation is needed for successful ...
