Yield10 Bioscience, Inc. is an agricultural bioscience company that is using its differentiated trait gene discovery platform—the Trait Factory—to develop improved Camelina varieties for the production of proprietary seed products, and to discover highly valuable genetic traits for the agriculture and food industries.
Our goals are to efficiently establish a high-value seed products business based on developing superior varieties of Camelina for the production of feedstock oils, nutritional oils, and PHA bioplastics, and to license our yield traits to major seed companies for commercialization in row crops, including corn, soybean, and canola.
DEVELOPING PHA BIOPLASTICS IN CAMELINA SEEDS
We have a significant track record and expertise in the metabolic engineering of plants. Our predecessor company, Metabolix, was a pioneer in the development of advanced PHA bioplastics production technology using engineered microbes and fermentation, and as a result, developed deep experience across the PHA bioplastics value chain. PHAs are naturally produced by some microbes as carbon storage molecules.
In addition, Metabolix supported a crop science research program to produce PHA biomaterials in crops as a potential low-cost production system. Historically, these efforts in crops were focused on producing PHB, the simplest member of the PHA family.
In its research, Yield10 has produced PHB in high concentrations in the seeds of oilseed crops or the leaves of biomass crops such as switchgrass. The PHB biomaterial is useful as a natural water treatment product and as a replacement for petroleum-based plastics. In addition, it produces a relatively abundant harvest of oil-containing seeds.
For more than a decade, Yield10 has been researching seed yield in Camelina, identifying and deploying new gene traits, evaluating the performance of these novel traits in field tests, developing PHA bioplastics in seed, and securing exclusive rights to omega-3 oils technology.
PHA BIOPLASTIC APPLICATIONS
FEED ADDITIVES
WATER TREATMENT
PLASTIC ALTERNATIVES
The first patent on the use of PHA in oilseed meal in animal feed was filed by our predecessor company, Metabolix, in the mid-1990s. While that patent has since expired, the chicken feeding studies described in that application demonstrated that the PHA in the feed was bioavailable as an energy source. Since then, several other reports have proven that the inclusion of microbially produced PHA at low levels can have beneficial pre-biotic effects, providing some level of protection against pathogens. In chicken feeding studies, low levels of PHA have been shown to improve feed conversion efficiency. Likewise, our current Camelina lines have produced up to 6% PHA in seed in our recent small-scale field trials.
PHA TRAITS: C3014 AND C3015
Yield10 filed a U.S. patent application in 2019 for new technology, potentially enabling low-cost production of PHA biomaterials in Camelina seeds. The patent application describes a discovery around maintaining the viability and vigor of Camelina seed programmed to produce high levels of the PHA biomaterial PHB.
By introducing the three genes encoding, the pathway for producing PHA from the plant metabolite acetyl-CoA, we have demonstrated the production of up to 10% PHB in Camelina seeds with good seedling viability in growth chambers.
We currently have two new PHA plastic traits, C3014 and C3015, in our development pipeline and we carried out successful first field tests in 2020. We are now progressing to scale up the two best lines, which showed PHA levels of up to 6% seed weight, to begin early product prototyping and market development studies for feed and water treatment applications.
