Yield10 Bioscience Chief Science Officer Dr. Kristi Snell to Highlight Camelina Platform for Producing PHB Biomaterials to Improve Water Quality at International Scientific Conference
Dr. Snell will discuss the progress made by the Yield10 team to achieve plant-based production of the simplest member of the natural PHA biopolymer family, PHB (polyhydroxybutyrate). The team engineered the PHB production pathway in the cytosol of plant cells, resulting in PHB levels of up to 10.2% of seed weight in the oilseed Camelina. The PHB containing seeds exhibited good seed germination, seedling emergence and survival. These results represent a significant step towards sustainable low-cost commercial production of PHB in plants. Yield10 recently filed a new U.S. patent application for producing PHB in plants using this novel method.
“Our conference presentation highlights the scientific breakthrough we achieved demonstrating the ability to produce PHB biomaterials at the level of 10% of the mature seed weight in seeds of the plant known as Camelina sativa,” said

Background on Camelina as a Cover Crop and the use of PHB in Water Treatment Applications
Members of the PHA biopolymer family are of commercial interest as natural, fully biodegradable replacements for plastics but also have well-defined applications in water treatment where they act as growth substrates for denitrifying bacteria normally present in water systems. Food production today is dependent on improved crop genetics and the use of fertilizers to provide essential nutrients. The combination of nutrient run-off from crop production and effluent from human and animal waste is causing nutrient pollution of waterways around the world. As the world’s population increases, the need to improve the sustainability of increasing food production and managing nutrient pollution will also intensify.
To address this growing need, Yield10 is approaching the problem at both the farm and the waste water treatment level. On the farm, after the food crop has been harvested, cover crops can be planted to absorb residual nutrients from the soil and reduce run-off into waterways. Planting conventional cover crops, however, typically results in a net reduction in farm income which is why they are not widely planted particularly in times when farmers are struggling. Yield10 is developing engineered Camelina to make new products, including PHB, which have the potential to open new markets and contribute an additional source of revenue for the farmer. Specifically, the seed harvested from the Camelina cover crop could be processed to produce PHB pellets, vegetable oil and animal feed, providing a new economic incentive to farmers to plant cover crops.
The PHB pellets would provide a natural, sustainable, capital-light, cost-effective, zero waste, maintenance-free approach to reducing nitrate levels in water systems. Yield10’s economic analysis indicates that the costs associated with producing PHB in crops could enable use of PHB in water treatment to be significantly expanded from current niche markets for aquarium water treatment into a range of waste-water treatment applications, including septic systems and municipal water treatment facilities. The key to realizing this opportunity, as well as the longer-term plastics replacement application, is developing sustainable, scalable, low-cost production systems for PHB and other natural PHA biopolymers.
