Application of affinity adsorption in thienamycin fermentation
(Springer-Verlag, 1989-02)
Many antibiotic fermentations are sensitive to high concentrations of their own product possibly due to product regulation and toxicity mechanisms. In this paper we discuss the feasibility of using affinity adsorption with ...
Charge-coupled device imaging of rapid calcium transients in cultured arterial smooth muscle cells
(Elsevier, 1990)
Transient changes in the concentration of intracellular free calcium are associated with the transduction of primary signals and the subsequent employment of Ca2+ as a second messenger in a multitude of cell types. These ...
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 ...
The rate of reaction between dilute hydrogen sulfide and ozone in air
(Elsevier, 1969-11)
The rate of reaction between dilute hydrogen sulfide and ozone in air was measured. Experimental data were obtained from two tubular, laminar-flow reactors having internal dia. of 3/8 in. and 1/4 in. On the basis of these ...
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 ...
Simple transporter trafficking model for amphetamine-induced dopamine efflux
(Wiley Subscription Services, Inc., A Wiley Company, 2007-07)
Amphetamine and its derivatives are important drugs of abuse causing both short-term excitatory and long-term addictive effects. The short-term excitatory effects are linked to amphetamine's ability to maintain high levels ...
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 ...
Phosphate feeding to permit growth while maintaining secondary product synthesis
(Springer-Verlag, 1988-02)
Maintaining high metabolic activities for extended periods by feeding small amounts of the growth limiting nutrient was examined for the production of cycloheximide by Streptomyces griseus . Batch studies indicated that ...
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 ...
