Probability Density Functional Method of Enzyme Effect on Denatured Protein Soil

Area of Science:

• Biochemistry
• Materials Science
• Surface Chemistry

Background:

• Protein soils require removal for aesthetic and hygiene purposes.
• Enzymes, heat, and oxidation are common methods for denaturing protein soils.
• Hemoglobin, a common blood soil, is particularly noticeable and responsive to denaturation.

Purpose of the Study:

• To investigate the enhanced detergency of denatured hemoglobin using enzymatic treatment.
• To analyze the cleaning mechanism using the probability density functional method.
• To correlate analytical findings with practical cleaning test results.

Main Methods:

• Enzyme immersing treatment of heat and oxidatively denatured hemoglobin in a sodium dodecyl sulfate (SDS) detergency solution.
• Application of the probability density functional method to evaluate soil adhesion and cleaning forces.
• Comparison of analytical results with empirical cleaning test data.

Main Results:

• Enzymatic treatment significantly improved the detergency of denatured hemoglobin.
• The probability density functional method demonstrated reduced soil adhesive force due to protein degradation.
• SDS detergency remained constant, highlighting the enzyme's specific contribution.
• Analytical results aligned with observed cleaning test outcomes.

Conclusions:

• The probability density functional method is a viable tool for analyzing enzymatic degradation of denatured protein soils.
• Enzymatic treatment effectively enhances the removal of denatured protein soils.
• Understanding soil adhesion dynamics is crucial for optimizing cleaning processes.
