immobilized enzymes

immobilized enzymes

CELLS (alive or dead) or ENZYMES anchored to a solid support for use in BIOCONVERSIONS. A continuous flow of substrate over the immobilized cells or enzymes will enable conversion to the desired product. Immobilized enzymes or dead cells are used for simple one- or two-step bioconversions. However, where multiple steps are involved, living cells are needed. Immobilized systems are used in industry to make various products, such as high-FRUCTOSE syrups, ASPARTIC ACID and semi-synthetic ANTIBIOTICS.
