Definitions

• the present disclosure relates to cleaning compositions comprising a specific glycoside hydrolase enzyme.
• the present disclosure also relates to methods of making and using such cleaning compositions.
• the present disclosure also relates to the use of the glycoside hydrolase enzyme.
• the detergent formulator is constantly aiming to improve the performance of detergent compositions.
• One particular challenge is the removal of certain soils of microbial origin from surfaces such as textiles. Such soils can be sticky and difficult to remove. Furthermore, because they are sticky they tend to adhere body soils and/or particulate soils to the surface, making soil removal difficult and having a tendency to build up over time. This may be particularly noticeable for example on collars and cuffs where incomplete cleaning may occur.
• glycoside hydrolases are enzymes that catalyze the hydrolysis of the glycosyl bond to release smaller sugars.
