Lichen Extract Formulation for Prion Breakdown
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chronic wasting disease (CWD) transmission among cervids is exacerbated by animal congregation and environmental contamination, with existing methods failing to effectively address the spread of infectious prions.
Innovation Solution
A formulation combining reindeer lichen extract (Cladonia rangiferina), lung lichen extract (Lobaria pulmonaria), and witch's hair lichen extract (Alectoria sarmentosa) is developed for use in feed pellets, protein blocks, drinking water, and spray cleaners to potentially break down infectious prions, with varying extract ratios and additives for stability and digestibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lichen extracts are added to feed formulations to break down prions, then CWD transmission is reduced, but formulation stability and digestibility must be maintained
Solution Approach 1:
The patent combines multiple lichen extracts (Cladonia rangiferina, Lobaria pulmonaria, Alectoria sarmentosa) with specific ratios (1:1:1 to 40:1:5 by weight) to create a composite formulation that maintains stability while achieving prion breakdown. This composite approach allows the synergistic effects of different lichen compounds to work together, resolving the contradiction between disease reduction and formulation stability.
Solution Approach 2:
The patent optimizes the concentration parameters of lichen extracts in the formulation, using ranges from 1% to 40% by weight for each extract type. By adjusting these parameters, the formulation achieves effective prion degradation while maintaining acceptable stability and digestibility characteristics.
2Reliability
If high concentrations of lichen extracts are used to maximize prion breakdown, then CWD transmission is more effectively reduced, but digestibility and animal health may be compromised
Solution Approach 1:
The patent establishes optimal concentration ranges for lichen extracts (1-40% by weight for Cladonia and Lobaria, 5-45% for Alectoria) that balance prion breakdown efficiency with animal health and digestibility. This parameter optimization prevents excessive concentrations that could harm animal health while maintaining effective disease reduction.
Solution Approach 2:
The use of a composite lichen extract mixture with specific ratios (1:1:1 to 40:1:5) creates a balanced formulation where the combined effects of different lichen species achieve prion degradation without the harmful effects of high concentrations of single extracts, thereby maintaining digestibility and animal health.
