Effect of mass transfer in a recirculation batch reactor system for immobilized penicillin amidase
(John Wiley & Sons, Inc., 1982-10-10)The effect of external mass transfer resistance on the overall reaction rate of the immobilized whole cell penicillin amidase of E. coli in a recirculation batch reactor was investigated. The internal diffusional resistance ... -

Vanillin as a product of ferulic acid biotransformation by the white-rot fungus Pycnoporus cinnabarinus I-937: identification of metabolic pathways
(Elsevier Science B.V., 1994)Ferulic acid metabolism was studied in cultures of the white-rot fungus Pycnoporus cinnabarinus I-937. After 6 days of growth, during the secondary metabolism of the fungus, the concentration of vanillin in the culture ... -
Mass transfer effects in solvent-free fat interesterification reactions: influences on catalyst design
(John Wiley & Sons, Inc., 1994-01-01)The use of solvent-free systems in the oil and fats industry is commonplace. Initial studies on interesterification were carried out in solvent systems because the lipase was immobilized solely by adsorption onto particles ... -
Factors affecting the esterification of lauric acid using an immobilized biocatalyst: enzyme characterization and studies in a well-mixed reactor
(John Wiley & Sons, Inc., 1995-04-05)The esterification of lauric acid with geraniol catalyzed by the commercially immobilized lipase preparation from Mucor miehei, Lipozyme(®), was studied in well-stirred flasks. The enzyme support was characterized in terms ... -
Pretreatment of wheat straw using combined wet oxidation and alkaline hydrolysis resulting in convertible cellulose and hemicellulose
(John Wiley & Sons Inc., 1996)The wet oxidation process of wheat straw has been studied as a pretreatment method to attain our main goal: To break down cellulose to glucose enzymatic, and secondly, to dissolve hemicellulose (e.g., for fermentation) ... -
New constraints between kinetic parameters explain the (un)identifiability of enzymatic rate constants
(John Wiley & Sons, Inc., 1996)For an enzymatic reaction the rate constants in the assumed mechanism (k1,k_1, etc.)sometimes cannot. When identifiability problems occur, these are obscured by redundancy occurring among the steady-state parameters. This ... -
Cell wall esterified phenolic dimers: Identification and quantification by reverse phase high performance liquid chromatography and diode array detection
(John Wiley & Sons, Ltd., 1996)An optimized high performance liquid chromatography (HPLC) procedure has been developed for the analysis and quantification of all of the known ferulic acid dehydrodimers, and the principle phenolic aldehydes and acids, ... -
Mass transfer and biochemical reaction in immobilized cell packed bed reactors: correlation of experiment with theory
(John Wiley & Sons Inc., 1996-07)A quantitative analysis of mass transfer combined with biochemical reaction and correlation of experiment with theory is carried out for immobilized cell packed bed reactors for the first time. Experimental data on flow ... -
A film diffusional effect on the apparent kinetic parameters in packed-bed immobilized enzyme reactors
(John Wiley & Sons, Inc., 1997-08)A film diffusional effect on the apparent kinetic parameters in packed-bed reactors containing the enzyme immobilized on the surface of a nonporous support was investigated. A comparison of the plug-flow reactor model ... -
Silica gel from rice hull ash: preparation and characterization
(American Association of Cereal Chemists, Inc., 1998-07)Rice hulls, a waste coproduct of the rice industry, is composed of 20% silica. The objectives of this study were to develop a method to recover silica from rice hull ash and produce silica gel, and to determine the physical ...
