Commercial laundry and commercial dishwashing, in which speciality machines may require speciality detergents. Even dry-cleaning may require detergent stain removers. 

In order to prove enzyme engineering feasibility, it was important to develop a model system. One of the prime considerations for any model would be the commercial potential of the model. Table I lists the major commercial enzymes and the market size in US dollars (5). The alkaline proteases (subtilisins) are clearly the major single class of enzymes in commercial use today, representing 25% of the total enzyme market of 600 million. The primary use of subtilisins is as additives in laundry detergents to aid in the removal of proteinaceous stains from cloth. 

Chelants in bleach-activated powder laundry detergents have a number of key roles to play - bleach stabilization, dye and fabric protection, stain removal, and scale inhibition. 

Enzymes. The most substantial advance in textile cleansing since the introduction of synthetic detergents has occurred through the introduction of low levels of enzymes into laundry detergent and presoak products. Both proteolytic and amylolylic enzymes are used by the industry to hydro yz.e protein and starch so that the smaller soil fragments are easier to remove. They are effective on stains with protein and carbohydrate substituents (such as body soils, many food stains, grass stains, blood, and many others). Enzymes are catalytic and specific and thus must be used at low levels in... 

A protein can be made to withstand higher temperatures by the introduction of additional disulfide bonds. For example, laundry detergents frequently contain enzymes to remove protein and blood stains. By replacing strategically located amino acid residues with cysteines, a modified enzyme results that stays in its active conformation in hotwater. 

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...

Protease is by far the most widely used of all detergent enzymes. Introduced in the 1960s, it has since become one of the more important components of detergent formulations [6]. Proteases aid in the removal of many soils commonly encountered by the consumer, such as food stains (cocoa, egg yolk, meat), blood, and grass. This enzyme hydrolyzes or breaks up the peptide bonds found in proteins resulting in the formation of smaller and more soluble polypeptides and amino acids. Since most enzymes have to function under high pH conditions, subtilisin, a bacterial alkaline protease, is commonly used in laundry detergents. This particular protease does not hydrolyze any specific peptide bond in proteinaceous stains but cleaves bonds in a somewhat random manner.
