Lesquerella: A Domestic Source of Hydroxy Fatty Acids.

The genus Lesquerella is a source of three different hydroxy fatty acids (HFA) in their seed oil with applications as a renewable raw material replacement for fossil fuel products. Lesquerella fendleri is the primary species from this genus in the process of commercialization and contains a HFA similar to castor oil, currently the only available commercial hydroxylated oil. Castor has a naturally occurring toxic protein (ricin) and a highly allergenic storage protein that prohibits production and processing in the U.S. About $50 million worth of castor oil is imported every year, primarily from India for industrial uses. L. fendleri is native to arid climates of the desert southwestern U.S. and production will likely occur in Arizona, Texas, and New Mexico.  Products targeted from this crop include biolubricants, biofuel additives to increase engine lubricity, biodegradable plastics, coatings, surfactants, and cosmetics.  The critical issue to bring this crop to commercialization is scale up of acreage from 100 to 100,000 acres.  Data collection, management, and dissemination are essential to address supply chain issues as are agronomics such as crop seeding, herbicides, and plant breeding to improve oil quantity and quality.  The economics of production and cost benefit ratios are also needed.  The result of this will be further opportunities for market expansion and a proven record of a successful new crop through interaction of the public and private sectors.
