Carbon is Key for Getting Algae to Pump Out More Oil

[font size=4]Findings may lead to new ways to produce raw materials for renewable fuels in microscopic “green factories”[/font]

The main finding was that feeding the algae more carbon (in the form of acetate) quickly maxed out the production of starch to the point that any additional carbon was channeled into high-gear oil production. And, most significantly, under the excess carbon condition and without nutrient deprivation, the microbes kept growing while producing oil.
“This overturns the previously held dogma that algae growth and increased oil production are mutually exclusive,” Xu said.
The detailed studies, conducted mainly by Brookhaven research associates Jilian Fan and Chengshi Yan, showed that the amount of carbon was the key factor determining how much oil was produced: more carbon resulted in more oil; less carbon limited production. This was another surprise because a lot of approaches for increasing oil production have focused on the role of enzymes involved in producing fatty acids and oils. In this study, inhibiting enzyme production had little effect on oil output.
