AI Technical Summary
Technical Problem
Existing cleaning compositions struggle to effectively remove complex stains comprising proteins, starch, mannans, and galactomannans due to the limited use of mannanases, which are less frequent than proteases and amylases, leading to suboptimal cleaning efficiency.
Method used
A composition comprising a mannanase variant with specific amino acid substitutions and high sequence identity, combined with amylase or protease variants, enhances the cleaning efficacy by synergistically addressing various stain components.
Benefits of technology
The enzyme blend provides improved cleaning performance on complex stains, including those with proteins, starch, mannans, and galactomannans, at lower temperatures, thereby increasing cleaning efficiency and reducing energy consumption.
