Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for degrading xanthan gum require multiple enzymatic activities and have not identified enzymes within the glycosyl hydrolase family 5 (GH5) with xanthan degrading activity, limiting efficient degradation in cleaning applications.
Innovation Solution
Development of detergent compositions comprising polypeptides with xanthan degrading activity within the GH5 family, which do not show significant sequence similarity to known xanthan degrading enzymes, and their use in combination with xanthan lyase for enhanced wash performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple enzymatic activities are used to degrade xanthan gum, then complete degradation is achieved, but device complexity and process complexity increase
Solution Approach 1:
The patent combines multiple enzymatic functions into a single GH5 polypeptide that exhibits both xanthan degrading activity and endo-beta-1,4-glucanase activity. This merging of functions reduces the number of separate enzymes needed while maintaining complete degradation capability, directly resolving the contradiction between complete degradation and system complexity
Solution Approach 2:
The GH5 polypeptide serves multiple functions: it degrades xanthan gum and simultaneously provides endo-beta-1,4-glucanase activity. This multi-functionality allows a single enzyme to replace what would traditionally require multiple separate enzymatic activities, reducing overall system complexity while ensuring complete degradation
2Device complexity
If GH5 polypeptides are used for xanthan degradation, then enzyme complexity is reduced, but wash performance may be insufficient without combination with xanthan lyase
Solution Approach 1:
The patent combines GH5 polypeptides with xanthan lyase in a synergistic enzyme system. This combination leverages the simplicity of GH5 enzymes while compensating for any performance limitations through the complementary action of xanthan lyase, achieving both reduced complexity and maintained wash performance
Solution Approach 2:
The invention creates a composite enzymatic system combining GH5 polypeptides and xanthan lyase. This composite approach allows the system to benefit from the reduced complexity of GH5 enzymes while achieving reliable wash performance through the synergistic interaction between different enzymatic components
