The Stability Improvement of -Amylase by Immobilization onto Chitin-Bentonite Hybrid.

Enzyme immobilization is a powerful method to improve the stability, reuse, and enzymatic properties of enzymes. The immobilization of the -amylase enzyme from on a chitin-bentonite (CB) hybrid has been studied to improve its stability. Therefore, this study aims to obtain the higher stability of -amylase enzyme to reduce industrial costs.

The Stability Improvement of -Amylase Enzyme from by Immobilization on a Bentonite Matrix.

The stability of the -amylase enzyme has been improved from using the immobilization method on a bentonite matrix. Therefore, this study aims to obtain the higher stability of -amylase enzyme from ; hence, it is used repeatedly to reduce industrial costs. The procedures involved enzyme production, isolation, partial purification, immobilization, and characterization.

Design of Wall-Destructive but Membrane-Compatible Solvents.

We report an extremely biocompatible solvent for plant cell walls based on a polar liquid zwitterion that dissolves cellulose, the most recalcitrant component of the plant cell walls. The polar liquid zwitterion does not affect the viability and activity of Escherichia coli, even at high concentrations. We demonstrate conversion of cell walls to ethanol via a starch-like process, namely successive dissolution, hydrolysis and fermentation in the same reaction pot.
