Sandia National Laboratories announced that it is helping HelioBioSys Inc. learn whether farming cyanobacteria on a large scale would be successful in producing sugar for biofuels.  HelioBioSys Inc. patented a group of three non-genetically modified marine cyanobacteria for the production of sugars, which can then be converted into a variety of fuels and chemicals.  Similar to algae, cyanobacteria grow in water and avoid competition with food crops for land, water, and other resources, making them a desirable renewable resource.  Cyanobacteria colonies, however, grow more efficiently than algae and excrete sugars directly into the water where they grow.  Whereas a typical algae farm may produce one gram of biomass per liter, small-scale testing of the cyanobacteria demonstrate that they can produce four to seven grams of sugar per liter of biomass, a 700 percent increase in efficiency.  Additionally, filtering sugar from water is simpler and more cost effective than extracting lipids from algae.
 
Now that HelioBioSys has proven the efficacy of the cyanobacteria in a closed, controlled, sterile laboratory, the company is working with Sandia researchers to understand where predation may cause issues by growing the organisms in large open air raceway systems, and to further study how the three types of cyanobacteria work together.

Sandia National Laboratories (Sandia) is investigating whether algae can be used to transform the Salton Sea, one of California’s largest and most polluted lakes, into a productive and profitable resource.  The Salton Sea Biomass Remediation project (SABRE), which is funded by the U.S. Department of Energy’s (DOE) Bioenergy Technologies Office (BETO), aims to use algae to rid the lake of pollutants while creating a renewable, domestic source of fuel and other chemicals.   Algae are known to thrive in environments like the Salton Sea, which contains elevated levels of nitrogen and phosphorus due to agricultural runoff. 
 
In the first phase of the project, Sandia partnered with Texas A&M AgriLife Research to investigate the efficacy of a new algal farming method, known as the “Algal Turf Scrubber” floway system.  The algae consume the nitrogen and phosphorus from the polluted water that is pumped into the system using solar-powered pumps.  Clean water is then deposited back into the lake.  
 
The second phase began in May and the initial results indicate that the system can produce a quantity of algae comparable to raceways, the traditional algal farming method.  The algae being grown are native to the area which makes it more resistant to attacks from local pathogens and predators.  By helping to clean polluted water, Sandia researchers have overcome a major criticism of algae as a biofuel source, specifically that farming algae requires too much water.  Additionally, the removal of pollutants, such as nitrogen, phosphorus, and other fertilizer components, is expected to provide a model of remediation for algae blooms.
