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 ...
1-Monoglyceride production from lipase-catalyzed esterification of glycerol and fatty acid in reverse micelles
(Wiley Subscription Services, Inc., A Wiley Company, 1991-08-20)
Glycerol-fatty acid esterification has been conducted with lipase from R. delemar in water/AOT/isooctane reverse micellar media, with the major product being 1-monoglyceride, a useful food-emulsifier. 1,3-diglyceride was ...
Validation of a two-parameter quantitative structure–activity relationship as a legitimate tool for rational re-design of horseradish peroxidase
(Wiley Subscription Services, Inc., A Wiley Company, 2007-09-01)
Previously reported rates of reaction between six mutant strains of the enzyme horseradish peroxidase (HRP) and a test substrate, 2-methoyxpyhenol, were found to correlate with characteristic binding distances computed ...
Fermentation monitoring by polymeric-resin-based microbiol assay
(Wiley Subscription Services, Inc., A Wiley Company, 1983-03)
A polymeric-resin-based microbiological assay is shown to yield results consistent with classical inhibition zone theory. This novel assay is applicable to cycloheximide, an antifungal antibiotic, at concentrations below ...
HCCH-TOCSY spectroscopy of 13 C-labeled proteins in H 2 O using heteronuclear cross-polarization and pulsed-field gradients
(Kluwer Academic Publishers; ESCOM Science Publishers B.V. ; Springer Science+Business Media, 1995-02)
A pulsed-field gradient-enhanced, heteronuclear cross-polarization-driven, 3D HCCH-TOCSY experiment is described, which in a single scan can achieve nearly ideal solvent suppression for protein samples in H 2 O solution. ...
Cell immobilization in k -carrageenan with tricalcium phosphate
(Wiley Subscription Services, Inc., A Wiley Company, 1982-08)
The objectives of this research were to investigate the growth of immobilized yeast cells in k -carrageenan gel and study the effect of trapping hydroxyapatite (tricalcium phosphate) crystals into the matrix. Using k ...
Countercurrent gradient chromatography: A continuous focusing technique
(Wiley Subscription Services, Inc., A Wiley Company, 1995-12-05)
The continuous separation of proteins was performed in a countercurrent gradient chromatography (CGC) system. A magnetically stabilized fluidized bed (MSFB) was used to establish true countercurrent contact of a solid resin ...
A model of the renal cortex and medulla
(Elsevier, 1967)
Mathematical models of the renal cortex and medulla are developed. The glomerular filtration rate is treated as an input parameter. The differential equations for transfer of water and solutes are developed under the ...
Computer modeling of antibiotic fermentation with on-line product removal
(Wiley Subscription Services, Inc., A Wiley Company, 1988-07-20)
The fermentation of Streptomyces griseus for the production of cycloheximide is similar to other antibiotic fermentations in that product synthesis is subject to feedback regulation and the desired product is degraded ...
