Solvent selection for solid‐to‐solid synthesis

Biotechnology and Bioengineering, 2002
AbstractThermolysin catalyzed solid‐to‐solid synthesis of the model peptide Z‐L‐Phe‐L‐Leu‐NH2 is practically feasible in water and a range of organic solvents with different physicochemical properties. Excellent overall conversions were obtained in acetonitrile, ethyl acetate, n‐hexane, methanol, 2‐propanol, tert‐amyl alcohol, tetrahydrofuran, toluene ...

Solvent selection for pharmaceuticals

Fluid Phase Equilibria, 2002
Abstract The presence of solvents is essential in all steps of pharmaceutical processes (reaction, separation, and formulation). For toxicological reasons, drug manufacturers are increasingly required to minimize the number of solvents employed in pharmaceutical processes.

Selective binding and solvent denaturation

Biopolymers, 1987
AbstractA primitive model for solvent denaturation is that the denaturant binds independently to sites exposed by the unfolding of the protein. For reagents like urea and guanidinium salts, this binding must be very weak since denaturation occurs only at very high concentrations.

Selective solvent delignification for fermentation enhancement

Biotechnology and Bioengineering, 1983
AbstractCellulose and hemicellulose in renewable biomass resources such as cornstover and wheat straw have been examined as substrates for the production of ethanol. A mixed culture of selected strains of Clostridium thermocellum and Clostridium thermosaccharolyticum are used to accomplish both the hydrolysis and fermentation of these carbohydrates in ...

Solvent Selection Strategies for Extractive Biocatalysis

Biotechnology Progress, 1991
AbstractThis report follows the development of systematic solvent screening strategies for the identification of superior pure solvents and introduces techniques for the identification of effective coextractants. Specifically, methods to predict the biocompatibility and extractant capability of solvents are discussed.

Selective adsorption of solvents in a multiscale device

Microfluidics and Nanofluidics, 2006
We have incorporated microspheres, 50 μm to 80 μm in diameter, of periodic mesoporous organosilica (inner surfaces up to 1000 m2/g and pore sizes in the nanometre range) with two types of organic functionalities (benzene and ethane bridges, respectively) inside microstructured channels (each 200 μm wide and 100 μm deep) and, exemplarily, monitored by ...
