Recombinant Host Cells for Malonate Production via Acyl-CoA Hydrolase
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current petrochemical-based production routes for malonate and malonate-derived compounds are low-yielding, environmentally damaging, and dependent on non-renewable feedstocks, requiring expensive wastewater and exhaust gas treatment.
Innovation Solution
Biological production of malonate using recombinant host cells engineered with heterologous nucleic acids encoding acyl-CoA hydrolases that convert malonyl-CoA to malonate, along with methods for detecting and purifying malonate, and converting it into other industrially important chemicals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If petrochemical-based production routes are used for malonate, then production capacity is maintained, but environmental damage increases and yield decreases
Solution Approach 1:
The patent changes the fundamental production parameters by switching from petrochemical feedstocks to renewable biological feedstocks (glucose, sucrose, cellulose). This parameter change simultaneously improves environmental sustainability and achieves higher malonate yields (up to 100 g/L) compared to conventional methods, directly resolving the contradiction between productivity and environmental harm
Solution Approach 2:
The patent replaces mechanical/chemical synthesis systems with a biological system using recombinant host cells expressing engineered enzymes (malonyl-CoA hydrolase). This substitution enables sustainable production with reduced environmental impact while maintaining high productivity through optimized biological pathways
2Productivity
If petrochemical-based production routes are used, then production continues, but reliance on non-renewable feedstocks increases
Solution Approach 1:
The patent creates a universal biological production platform that can process multiple renewable feedstocks (glucose, sucrose, cellulose, hemicellulose) through the same recombinant host cell system. This multi-functionality ensures continuous production capability while adapting to various renewable resources, eliminating dependence on any single non-renewable petrochemical feedstock
Solution Approach 2:
The patent fundamentally changes the feedstock parameter from non-renewable petrochemicals to renewable biological materials. The engineered metabolic pathways in host cells are optimized to convert these renewable feedstocks into malonate, ensuring both continuous production and sustainability
3Ease of manufacture
If existing production methods are used, then current processes are maintained, but production cost increases due to expensive wastewater and exhaust gas treatment
Solution Approach 1:
The patent converts the harmful byproducts of conventional synthesis into benefits by using a biological system that produces minimal waste. The recombinant host cells metabolize feedstocks through natural pathways, converting potential harmful intermediates into useful products or easily biodegradable byproducts, thereby eliminating expensive wastewater and exhaust gas treatment requirements
Solution Approach 2:
The patent replaces complex chemical synthesis mechanisms with simpler biological metabolism. The engineered host cells perform multiple synthesis steps in one biological system, eliminating the need for separate treatment processes for wastewater and exhaust gas, thus reducing both operational complexity and production costs
