Algae research continues to get a lot of focus. University of Nebraska-Lincoln has announced that it will expand its algae research center this year, dedicating more space in the Beadle Center greenhouse for the work. As reported by Biomass Magazine, the university received $1.9 million in federal funding for it current research in alternative energy and is anticipating additional funds.

Scientists, using natural algae strains, will begin by growing algae in bags. From there, they will move to oblong ponds. Along the way, they hope to achieve three goals as identified by Paul Black, a lipid biochemist at UNL who will be participating in the study: identify the best strains for maximum oil production; identify optimal growing conditions; and modify the algae for maximum cell density.

Currently, the research team is working with a photo bioreactor that is designed to increase cell density per unit volume from about two grams per liter to eight to 10 grams per liter, by exploring maximum light and carbon dioxide conditions, Black said. Cell density is important because their is a possibility of making it simpler to harvest the algae. “You’re in essence, fooling them,” said Black.

Another area of concentration is optimizing oil extraction. According to Black, the team has used organic solvents and is also looking at using carbon dioxide and high pressure.

Although there is no immediate timeframe for the establishment of tangible results, Black anticipates some compelling data to be forthcoming within a year.
