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 ...
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 ...
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 ...
Fischer-tropsch synthesis on charcoal-supported molybdenum: The effect of preparation conditions and potassium promotion on activity and selectivity
(Elsevier, 1985)
High dispersion and high activity charcoal-supported molybdenum catalysts were prepared using incipient wetness and equilibrium adsorption methods. Activities and selectivities of these catalysts were tested after reducing ...
Report on the catalytic activity of 6-heteropolymolybdates as potential Fischer-Tropsch synthesis catalysts
(Elsevier, 1986-02-14)
Unsupported and supported decomposition products of 6-heteropolymolybdates were tested as possible Fischer-Tropsch synthesis catalysts. Depending on the heteroatom, the activity changes significantly and the best supported ...
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 ...
CO hydrogenation on Ru/Al2O3: Selectivity under transient conditions
(Elsevier, 1987-06)
Transient response and isotopic tracer techniques were used to investigate the surface coverages of the reactants and the selectivity of ruthenium/alumina catalysts in CO hydrogenation. Two forms of carbon--active carbidic ...
Techniques for preparing hydrogel membrane capsules
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1988-12)
Techniques for preparing four kinds of hydrogel membrane capsules are described. In the present process the material being encapsulated remains in its original environment in an aqueous suspension. Also, capsule characteristics ...
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 ...
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 ...
