The research article details breakthrough technology developed by scientists with Bio Architecture Lab (BAL) using a microbe to extract the sugars in macroalgae that could further the use of seaweed as a feedstock for advanced biofuels and renewable chemical production.
“About 60 percent of the dry biomass of seaweed are sugars, and more than half of those are locked in a single sugar – alginate,” said Daniel Trunfio, Chief Executive Officer at Bio Architecture Lab. “Our scientists have developed a pathway to metabolize the alginate, allowing us to unlock all the sugars in seaweed, which therefore makes macroalgae an economical alternative feedstock for the production of renewable fuels and chemicals.”
“It is both an incredible scientific achievement and a distinguished honor to be published in Science, and I am very proud of our team,” said Trunfio. “It is yet another strong validation of BAL’s breakthrough technology.”
Seaweed can be an ideal global feedstock for the commercial production of biofuels and renewable chemicals because in addition to its high sugar content it has no lignin, and it does not require arable land or freshwater to grow. Globally, if three percent of the coastal waters were used to produce seaweed than more than 60 billion gallons of fossil fuel could be produced. Today, in many parts of the world, seaweed is already grown at commercial scale. BAL currently operates four seaweed farms in Chile and has had great success in growing seaweed at economically viable production yields.
BAL was a beneficiary of the highly selective U.S. Department of Energy’s Advanced Research Projects Agency – Energy (ARPA-E) awarded to DuPont, for the development of a process to convert sugars from seaweed into isobutanol.
