The new group aims to lower the costs of renewable energy procurement through combined purchasing power, solicit new renewable energy opportunities and projects, promote the development of a "green" low-carbon economy, and support the state's commitments to source 50 pct of New York's energy requirements from renewable sources by 2030. The consortium will also focus its efforts on projects that will be ready for operation no later than 2020.

In the new technology, a single algal cell is captured in a droplet of water encapsulated by oil then millions of algal droplets squeeze onto a chip about the size of a quarter. Each droplet is a "micro-bioreactor", a highly controlled environment in which algal cells can grow and replicate for several days, forming a genetically homogenous colony that goes through its typical biological reactions, including the production of lipids.
The researchers first validated the chip system with algae known to grow faster or slower, or produce more or less lipid. They then screened 200,000 chemically mutated cells, identifying six mutants with both faster growth and higher lipid content. The screening, done on-chip, uses fluorescence detection of chlorophyll, representing total cell mass, and BODIPY, a fluorescent molecule that binds to lipids. All mutants with potential for improved growth or lipid production were recovered and verified off-chip.
The tools for improving throughput are already in development, including larger chips that can screen millions of droplets in one experiment.
With the discovery and development of much more efficient algal strains, commercial-scale production of biofuel from algae may finally be a realistic promise.
The research was supported by the National Science Foundation. (Source: Cornell University, PR, Plant Direct, 28 Sept., 2017) Contact: Cornell Univ., George Lowery, (607) 255-2171, email@example.com, www.cornell.edu; Texas A&M, Arum Han , (979) 845-9686;
