Lipase (Lipex)

Lipases were first added to washing products in the early 1990s.

Lipex® is a liquid enzyme preparation containing a lipase suitable for use in detergent preparations.

SOURCE

Lipex® is produced by submerged fermentation of a genetically-modified microorganism. The enzyme protein is not itself modified. After fermentation, the enzyme is separated from the production organism and purified.

COMMERCIAL USES

Lipex® is used in detergent formulations to remove fat and oil-based stains, e.g., salad oil.

EDUCATIONAL USES

Common methods of assaying the activity of lipases in schools are to use tributyrin or egg yolk agar (similar to the method used for proteases) or to measure the change in pH using phenolphthalein when the enzyme is added to milk or a solution of non-dairy creamer (the sort sold for adding to coffee). The latter method is effective, but will be affected by the pH of the water used to dissolve the creamer, so check the pH of your distilled water. See also: Practical Biology. Investigating the effect of temperature on the activity of lipase.

ACTIVITY

Lipex® degrades edible fats and oils to fatty acids and glycerol. Lipex® is effective under neutral to alkaline conditions (optimally at pH 10) and performs across a broad temperature range (30–60 °C).

STORAGE

Lipex® should be stored in a fridge at 3–5 °C. Do not freeze.

SAFETY

DANGER. May cause allergy or asthma symptoms or breathing difficulties if inhaled. See Safety Data Sheet for further advice.
