Improvement of properties by immobilization http://www.scitopics.com/IMPROVEMENT_OF_ ENZYME_PROPERTIES_VIA_IMMOBILIZATION_ TECHNIQUES.html This webpage focuses on the means by which enzyme activity can be stabilized or improved in an immobilized state compared with the same enzyme free in aqueous solution. Immobilized enzymes http://www.rpi.edu/dept/chem-eng/Biotech-Environ/viet/ nelly.html Thi...

This paper presents some results concerning the immobilization through chemical bonds of some biologically active compounds on the maleic anhydridemethyl methacrylate) copolymer. The high reactivity of the anhydride cycle of the polymer has allowed us to obtain conjugates in which the biologically active compounds of some heterocyclic compounds are immobilized on the polymeric support through a...

Organic foods have great importance in environment sustainability and human nutrition. However, they are commercialized with greatly reduced shelf life, especially fruits and vegetables. Considerable amounts of vegetables are lost due to their rapid deterioration by microorganisms such as fungi and bacteria. In this work cell wall degrading enzymes (CWDE) produced by Trichoderma asperellum (T00...

The objective of this research was to determine the effect of sugar or fatty acid in sugar ester compounds on the surface-active properties and antimicrobial activities of these compounds. Disaccharides of medium-chain fatty acid monoesters were synthesized through transesterifications by immobilized lipase (Lipozyme TLIM) to yield nine monoesters for subsequent study. Their antimicrobial activ...

mn(ii) salen complex immobilized on nano silicagel was prepared by incorporating mn(ii) salen complex into a nanosilica matrix and characterized by tga, xrd, atomic absorption spectroscopy and was successfully applied as catalyst for the oxidation of alcohols. oxidation of a series of alcohols in acetonitrile over immobilized mn(ii) salen complex using tetrabutylammonium peroxymonosulfate (tbao...

substrates' concentration profile was studied in a porous matrix containing immobilized amyloglucosidase for glucose production. this analysis was performed by using an analytical method called least square method, and the results were compared with numerical solution. effects of effective diffusivity, michael's constant, maximum reaction rate and initial substrate concentration were studied on...

A series of biocide-containing polyethylene composites were obtained using novel guanidine-containing copolymers immobilized on an inert mineral carrier. Multispecies microbial communities isolated from the surface samples either incubated or found in environment, and their taxonomic composition was determined. Biofilms reconstructed microorganisms different ecotopes shown to intensively foul s...

Techniques of immobilization of microbial- cells have been established by multifunctional reagents such as glutaraldehyed on a solid support. Immobilized cell reactor was designed to demonstrate stability of cross linking of whole cells for the production of organic acids. An eighty-six percent conversion of glucose was obtained for an eight hour retention time. The immobilized cell reacto...

Pollutant degradation in biotrickling ®lters for waste air treatment is generally thought to occur only in the bio®lm. In two experiments with toluene degrading biotrickling ®lters, we show that suspended microorganisms in the recycle liquid may substantially contribute to the overall pollutant removal. Two days after reactor start up, the overall toluene elimination capacity reached a maximum ...
