Laundry lipases

Lipases are also active during a certain period of the drying step (51), eg, Lipolase displays maximum activity when the moisture content on the fabric is 20—30% by weight. This means that significant decomposition of any residual fatty matter will take place while the laundry is drying. This hydrolytic activity does not result in an immediate advantage in terms of fat removal however, next time the stained fabric is washed the stain will be removed more effectively. 

Cutinase is a hydrolytic enzyme that degrades cutin, the cuticular polymer of higher plants [4], Unlike the oflier lipolytic enzymes, such lipases and esterases, cutinase does not require interfacial activation for substrate binding and activity. Cutinases have been largely exploited for esterification and transesterification in chemical synthesis [5] and have also been applied in laundry or dishwashing detergent [6].

Lipases are found in a wide variety of bacteria, yeasts, and filamentous fungi. Due to their unique properties, lipases are used in all applications where fats are modified or need to be removed. In the detergent industry, lipases are added to laundry detergents for the removal of fat-containing stains. In the paper industry, lipases remove fatty pitches from...

One unusual example of a hard surface cleaner of this type claims a residual effect on the surface that reducing the cleaning effort needed on subsequent cleanings. The surprising part of this invention is that the claim is based, in part, on the presence of lipase in the formula [226], This is a rare example of the use of an enzyme in a consumer-intended hard surface cleaning formula. The use of enzymes in hand dishwashing, automatic dishwashing, and laundry is quite common.

Lipases used in laundry detergents and in other bulk applications do not require enzyme immobilization however, an increasing number of applications in synthesis and biotransformation demand an immobilized biocatalyst for efficient use. It has been claimed that the success of a lipase catalyzed biotransformation for the production of certain pharmaceuticals depends on immobilization. For example, in the industrial preparation of the chiral intermediate used in the synthesis of Diltiazem, the lipase from Serratia marcescens was supported in a spongy matrix, which was used in a two-phase membrane bioreactor (Cowan 1996). 

The detergent industry produces many proteases and lipases in huge amounts. These are largely used as additives for detergents to effect the hydrolysis of proteinogenic and fatty impurities in the laundry process. 

Protease-containing liquid aqueous detergents are well known, especially in the context of laundry washing, where they attack protein-based stains. A commonly encountered problem in such protease-containing liquid aqueous detergents is the degradation second enzymes (e.g., lipase, amylase, and cellu-lase, or protease itself) by the proteolytic enzyme in the composition. As a... 

Enzymes are used as ingredients in laundry and dishwashing detergents to improve their efficiency. Their functional efficiency depends on the detergent s components, type of stain to be removed, water temperature, and hardness. Major enzymes used for this purpose are proteases, amylases, lipases, and cellulases. Proteases, which are the most widely used enzymes in the detergent industry, enhance the breakdown... 

However, when platinum (Pt) is used as a catalyst, the reaction occurs rapidly. In the body, biocatalysts called enzymes make most metabolic reactions proceed at rates necessary for proper cellular activity. Enzymes are added to laundry detergents to break down proteins (proteases), starches (amylases), or greases (lipases) that have stained clothes. Such enzymes function at the low temperatures that are used in home washing machines, and they are biodegradable as well. 

After the successful introduction of proteases for the removal of proteinaceous stains in laundry detergents, the next challenge was the development of lipases for the removal of greasy stains. The search for suitable lipases however turned out to be far more difficult than the introduction of proteases.
