HelioBioSys uses a mixed population of carefully selected non-genetically modified marine cyanobacteria that obtain their energy from the sun, and carbon and nitrogen from the atmosphere. These highly efficient and robust bacteria are grown in seawater in managed open ponds. Our system produces complex polysaccharides that are easily separated from the biomass. The polysaccharides may be processed directly to create a variety of bioplastics or used as ingredients in cosmetics and sunscreens.
