Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing cannabinoids from Cannabis sativa plants are inefficient, costly, and lack the necessary control and speed to meet market demands, while existing fermentation processes using microorganisms face challenges in achieving high cannabinoid production and purification.
Innovation Solution
Engineering yeast strains to produce cannabinoids through controlled fermentation by localizing enzymes involved in cannabinoid production to the cytosol, peroxisome, or secretory pathway compartments, utilizing fatty acid feedstocks to generate fatty acyl-CoA, and employing polyketide synthases and olivetolic acid cyclases to produce cannabinoids efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If plant-based production methods are used for cannabinoids, then natural product availability is improved, but manufacturing cost and time efficiency deteriorate
Solution Approach 1:
The patent replaces plant-based biological systems with a microorganism-based fermentation system. Yeast cells are engineered to express cannabinoid biosynthesis enzymes, substituting the complex plant metabolic machinery with a controllable microbial fermentation process that operates faster and at lower cost.
Solution Approach 2:
The patent changes the biological host parameter from plant to microorganism (yeast), and controls fermentation parameters (temperature, pH, nutrient feed rates) to optimize cannabinoid production. This allows precise control over production rate and cost, overcoming the limitations of plant-based methods.
2Extent of automation
If existing fermentation processes are used, then controlled production is improved, but cannabinoid production efficiency and purification difficulty deteriorate
Solution Approach 1:
The patent segments the cannabinoid biosynthesis pathway into distinct enzymatic steps and localizes them to specific cellular compartments (cytosol, peroxisome, endoplasmic reticulum, Golgi apparatus). This compartmentalization improves metabolic efficiency and facilitates controlled production while simplifying downstream purification.
Solution Approach 2:
The patent uses engineered yeast cells as an intermediary system that converts simple fatty acid feedstocks into complex cannabinoids through controlled fermentation. This intermediary approach maintains the benefits of controlled production while achieving high efficiency and simplifying purification compared to direct plant extraction.
3Adaptability or versatility
If enzymes are distributed throughout the cell, then production flexibility is improved, but production efficiency deteriorates
Solution Approach 1:
The patent assigns specific enzymes to specific cellular compartments based on their functional requirements. For example, fatty acid activation enzymes are localized to the cytosol, while cannabinoid synthase enzymes are targeted to the endoplasmic reticulum or Golgi apparatus. This localized arrangement optimizes substrate channeling and metabolic efficiency while maintaining production flexibility through genetic control.
