Methods for Measurement and Control of Water in Nonaqueous Biocatalysisic) media. Most biocatalysts are inactive if fully dehydrated, and the reaction rate is stimulated by increasing hydration, at least at first. The rate of the desired reaction can become slower again if water levels increase too much, particularly when a hydrolytic side reaction becomes significant.

Water Activity Control for Lipase-Catalyzed Reactions in Nonaqueous Mediaemoving the water produced during the reaction. Many researchers have proposed several methods for water removal, such as headspace evacuation (.,.), pervaporation (.), use of molecular sieve (.), salt hydrate pairs (.,.), saturated salt solution, adsorption (.), and sparging of dry inert gas throug

Immobilization of Enzymes and Control of Water Activity in Low-Water Mediaticles with controlled pore sizes (.). This type of porous Celite differs from Celite powder in its capacity to adsorb water (more than 90% of Celite weight). Recently, it has been demonstrated that Celite R-640 in organic solvent adsorbs and releases water such that water activity (a.) is maintaine

Calorimetric Methods in Evaluating Hydration and Solvation of Solid Proteins Immersed in Organic Sol may be drastically changed by an organic solvent. Considering the variety of opportunities in use of different nonaqueous media, correct selection of organic environments presents a great challenge to biotechnological scientists and engineers. Such a selection needs the understanding of molecular m

The Effects of Crown Ethers on the Activity of Enzymes in Organic Solventsrther boosted by the recognition that enzymes can operate in organic solvents. The use of nonaqueous media for enzymatic conversions offers a number of advantages, like enhanced thermal stability of the enzyme, increased substrate solubility, a shift of the equilibrium in favor of synthesis over hyd
