Viscozyme is a multi-enzyme complex containing a wide range of carbohydrases. It also acts on branched pectin-like substances found in plant cell walls. One of its more interesting uses in the school laboratory is in the production of plant cell protoplasts from lettuce leaves.

SOURCE

Viscozyme is produced by a selected strain of the fungus Aspergillus aculeatus.

USES

Viscozyme finds a wide range of uses in industry, especially where useful products are being extracted from plant materials and in the processing of cereals and vegetables. It can enhance the availability of starch in fermentation by degrading the non-starch polysaccharides that are often bound to starch in plant materials. It generally reduces the viscosity of materials derived from plants and can hence improve extraction yields. The reduction in viscosity of cellulosic substrates can easily be measured in the school laboratory.

An interesting educational application is in the degradation of leaf tissue, to produce protoplasts and plant cell mixtures that can be studied under the microscope.

ACTIVITY

Viscozyme contains a range of carbohydrases including arabanase, cellulase, beta-glucanase, hemicellulase and xylanase. It also breaks down branched pectin-like substances found in plant cell walls. The optimal conditions for Viscozyme with its several and complex activities are a pH range of 3.3-5.5 and a temperature of 25-55 °C.

STORAGE

The enzyme preparation should be stored at 3-5 °C. At this temperature the enzyme will maintain its declared activity for at least a year. At 25 °C, you can expect the enzyme to maintain its declared activity for at least 3 months.
