Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional fermentation processes using natural fungus are used to produce MPA, then MPA can be produced, but the production process is laborious and inefficient
Solution Approach 1:
The patent extracts and isolates specific genes (mpaA, mpaC, mpaF) encoding enzymes involved in MPA synthesis from the natural fungus Penicillium brevicompactum. By separating these key genetic elements from the complex natural fermentation system, the invention enables targeted expression in host cells, thereby improving production efficiency while simplifying the manufacturing process.
Solution Approach 2:
The patent uses expression vectors as intermediaries to carry the isolated mpa genes into host cells. These vectors serve as mediators that enable the transfer and expression of the gene sequences, facilitating efficient MPA production without requiring the complete natural fermentation system.
2Productivity
If genes encoding MPA synthesis enzymes are identified and expressed in host cells, then MPA production efficiency improves, but the device and process complexity increases due to genetic engineering requirements
Solution Approach 1:
The patent segments the MPA synthesis pathway by identifying and isolating specific genes (mpaA, mpaC, mpaF) that encode key enzymes. Instead of attempting to transfer or modify the entire fungal genome, the invention focuses on these discrete genetic elements, making the genetic engineering process more manageable and less complex while maintaining high productivity.
Solution Approach 2:
The patent applies local quality by introducing only the specific mpa genes needed for MPA synthesis into the host cells, rather than modifying the entire organism. This targeted approach allows the host cells to acquire the specific capability of producing MPA efficiently without requiring comprehensive genetic modification, thereby reducing overall system complexity.
