In California, Sustainable Green Technologies announced that SGT scientists have uncovered a “lipid trigger” in green algae. Under certain conditions, many microalgae had appeared to “flip a switch” that increased production and storage of oils instead of starch. SGT said that it is able to activate the switch and to create “obese algae.
“We found the waste from our biohydrogen system sparked tremendous growth of our green algae, and more importantly, massively increased lipid production and storage within our algae,” said SGT CSO Dr. Elmar Schmid. SGT’s CSO. In other words, our algae became obese within one week! We now have a highly efficient, cost-effective way of producing large amounts of algae oils for biodiesel fuel production. On top of that, we can produce clean biohydrogen from the resulting biodiesel refinery waste!” exclaims Dr. Schmid.
SGT’s biohydrogen-producing microbes can convert a variety of feedstock into biohydrogen energy including glycerol waste, sugars derived from sugar cane and sugar beet, brewery waste. SGT said it had also applied for a DOE grant for its biohydrogen and algae system.
