Plants Producing Modified Levels of Medium Chain Fatty Acids Engineering Crops to Make Industrial Oils and Biofuel

This patent describes engineering plants so they build up more medium-chain fatty acids, such as lauric and myristic acid, in their tissues, giving a renewable source of industrial oils and biofuel. It comes from Nuseed Global Innovation Ltd., the innovation arm of the seed technology company Nuseed.

The Problem

Many valuable oils and chemicals come from medium-chain fatty acids, which today are mostly extracted from tropical crops like coconut and palm. That supply is geographically limited, tied to land-use and sustainability concerns, and vulnerable to price swings. At the same time, most oil crops store their oil only in the seed, which is a small fraction of the plant, leaving the abundant leaves and stems largely unused. If ordinary crops could be engineered to accumulate medium-chain fatty acids, and to do so in their vegetative parts rather than only in seed, growers could harvest far more oil per hectare from land already in production. The difficulty is that plant fat metabolism is tightly regulated, so making a plant produce and store the right chain-length fatty acids in the right tissues requires precise genetic changes.

What This Invention Does

The invention provides methods of producing industrial products from plant lipids, particularly from the vegetative parts of plants, along with plants that have increased levels of medium-chain fatty acids such as lauric acid and myristic acid. The core approach combines modifications in a fatty acid thioesterase, an enzyme that helps set the chain length of the fatty acids a plant makes, with changes in one or more acyltransferases, enzymes that direct fatty acids into stored oil. Together these genetic engineering changes push the plant to make more medium-chain fatty acids and to pack them into tissue as oil. The patent also covers a process for extracting the lipids and, in some embodiments, converting the lipid into hydrocarbon products, so the invention spans the engineered plant, the oil it stores, and the downstream industrial and fuel products made from it.

Key Features

• Medium-chain enrichment. Plants are engineered to accumulate higher levels of medium-chain fatty acids like lauric and myristic acid.
• Oil in vegetative tissue. The approach targets oil accumulation in leaves and stems, not just seed.
• Paired enzyme changes. Modifications in a fatty acid thioesterase are combined with changes in one or more acyltransferases.
• Extraction process. The patent covers a process for extracting the lipids from the plant material.
• Fuel and chemicals. In some embodiments the lipid is converted into hydrocarbon products such as biofuel.

Who Is Behind It

The applicant is Nuseed Global Innovation Ltd., part of Nuseed, a global seed technology company with expertise in oilseed genetics and crops such as canola, carinata, and sorghum. The named inventors include Kyle B. Reynolds, Thomas Vanhercke, Anna El Tahchy, and Qing Liu. This filing is a divisional application from an earlier related Australian application.

Why It Matters

Turning ordinary crops into high-yield sources of medium-chain oils could ease reliance on tropical plantations and provide renewable feedstock for detergents, lubricants, and fuels. Producing oil in the whole plant rather than only in seed dramatically raises the potential yield per hectare, which matters for both economics and land use. As demand grows for sustainable vegetable oil and bio-based industrial inputs, protecting these engineered crops in Australia, a major agricultural producer, is strategically significant.
