Formation of polyol–fatty acid esters by lipases in reverse micellar media
(Wiley Subscription Services, Inc., A Wiley Company, 1992-06-05)
The synthesis of polyol–fatty acid esters has strong implications in such industries as foods, cosmetics, and polymers. We have investigated these esterification reactions employing the polyols ethylene glycol, 2-monoglyceride, ...
Application of membrane-based preferential transport to whole broth processing
(Wiley Subscription Services, Inc., A Wiley Company, 1997-08-20)
Preferential transport in adsorptive membranes can be used to selectively remove biochemicals directly from fermentation broths. During preferential transport, an adsorbing solute is selectively transported across the ...
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 ...
Modeling nutrient behavior in Wetlands
(Elsevier, 1988-01)
A simple mathematical model os developed which permites dynamic simulation of wetland hydrology and of nutrient-driven interactions between wastewater and the wetland ecosystem. Spatial variations due to surface water flow ...
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 ...
