NMC Researchers Conduct Field Trials of Algal Strains

Co-PIs Alina Corcoran of the New Mexico Consortium (NMC) and Shawn Starkenburg of Los Alamos National Laboratory, along with industrial partners, are starting an exciting four year project built upon outdoor algal cultivation. The project is entitled Optimizing Selection Pressures and Pest Management to Maximize Algal Biomass Yield (OSPREY).

In the biofuel industry scientists often create algal strains with high productivity in the lab, only to find these strains fail when cultured in the field. Conversely, field strains can be robust, but may lack desired qualities such as high lipid content. Field trials of algal strains is much needed in this line of research.

The goal of OSPREY is to balance the selection pressures that strains experience in the lab with those they experience in the field – ultimately to make strains that are both productive and resilient to environmental stressors.

field trials for algal strainsThe project will start with a field-adapted strain from an industrial partner Qualitas Health. This strain will be distributed to research partners in California, Hawaii, and New Mexico where it will be allowed to naturally develop robustness in different environments. Researchers at each location will grow the same strain for four years  to study how it changes. Does it evolve to be more resilient to desert environments or coastal environments, and can the researchers capture its qualities and use them to create more productive strains?

Researchers will also use non-GM laboratory approaches at New Mexico State University, Los Alamos National Laboratory, and the University of California San Diego to improve the baseline field strains.

This research is unique because it relies on natural, outdoor selection pressures to drive fitness in the algal strains that have already been identified as standards in the industry.

PIs at the New Mexico Consortium and Los Alamos National Laboratory will lead the project. Industrial partners include Qualitas Health, Cyanotech Corporation, and Phase Genomics. Academic partners include Colorado State University, New Mexico State University, and the University of California San Diego.

This field trials of algal strains project is funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) under the Bioenergy Technologies Office Award Number DE-EE0008902.
