Microbial conversion of fatty acid methyl esters to linear alpha olefins

Overview

This innovative research focuses on the metabolic engineering of the oleaginous yeast Yarrowia lipolytica to create a microbial cell factory capable of converting fatty acid methyl esters into linear alpha olefins. These olefins are valuable chemicals with applications in various industries, including plastics, lubricants, and surfactants. The process aims to produce olefins with specific carbon chain lengths (C8-C16), enabling tailored production for diverse industrial needs.

Technical specifications

The core of this technology involves the genetic modification of Yarrowia lipolytica. The yeast's metabolism is optimized to efficiently degrade fatty acid methyl esters into intermediate fatty acids, which are then converted into target olefins through enhanced beta oxidation cycles. Key enzymatic steps involve:

• Thioesterases and lipases for effective feedstock degradation
• Fatty acid decarboxylases for the conversion of fatty acids into linear alpha olefins

The project is structured in phases, with the initial year focusing on engineering the metabolic pathways and subsequent years dedicated to enzyme optimization and process refinement.

Technology readiness level

Currently, this technology is at TRL 2, indicating that the concept and application have been formulated and early-stage experimental proof-of-concept activities are underway. Future efforts will be directed towards pathway validation and optimization of metabolic and bioprocess conditions to enhance production efficiency.
