Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If isolation methods are used to obtain indole alkaloids from natural sources, then the compounds can be obtained, but the yield is low and large amounts of biomass are required
Solution Approach 1:
The patent replaces mechanical/isolation-based extraction methods with a biological production system using recombinant microorganisms. The microorganisms express heterologous biosynthetic pathways to produce indole alkaloids directly, substituting the mechanical isolation process with a biological synthesis process that achieves higher yields without requiring large amounts of starting biomass
Solution Approach 2:
The patent changes the fundamental parameter of production methodology from extraction/isolation to biosynthetic production. By introducing heterologous genes encoding biosynthetic enzymes into recombinant microorganisms, the system transforms the production parameters to achieve high-yield generation of indole alkaloids from simple precursors rather than from complex plant biomass
2Ease of manufacture
If chemical synthesis strategies are used to produce monoterpene indole alkaloids, then compounds can be synthesized, but the process is highly complicated and involves toxic solvents
Solution Approach 1:
The patent replaces chemical synthesis methods with biological synthesis methods. Recombinant microorganisms express enzymatic pathways that naturally produce indole alkaloids, substituting complex multi-step chemical reactions with biological catalysis. This eliminates the need for toxic solvents and complicated synthetic procedures while maintaining product generation
Solution Approach 2:
The recombinant microorganisms perform the synthesis autonomously using their own cellular machinery and metabolic pathways. The engineered cells take up simple precursors and automatically convert them to indole alkaloid products through expressed biosynthetic enzymes, eliminating the need for external toxic reagents or complex synthetic conditions
3Quantity of substance
If chemical synthesis strategies are used to produce monoterpene indole alkaloids, then compounds can be synthesized, but the yield is low
Solution Approach 1:
The patent replaces complex chemical synthesis with biological production in recombinant microorganisms. The cellular machinery and enzymatic pathways naturally achieve high efficiency in converting precursors to products, eliminating the need for complex multi-step chemical procedures while simultaneously achieving high yields
