Zackary Johnson, Arthur P. Kaupe Assistant Professor of Molecular Biology in Marine Science at 老牛影视鈥檚 Nicholas School of the Environment, has received a three-year grant for up to $5.2 million from the U.S. Department of Energy to establish a consortium to study the extraction, development and commoditization of various products from algae.

The Marine Algae Industrialization Consortium 鈥 or MAGIC, for short 鈥 will include both  university and corporate partners.

Algae-based oil has been pursued as a renewable source of fuel since the 1970s, but high production costs prevented it from becoming a competitor with crude oil. The consortium鈥檚 goal, Johnson says, is to find ways to drive down the cost of oil extracted from algae. To do this, they need to maximize the value of other products that can be made from algae, such as proteins.

 鈥淭o make algae a competitive player in this field you have to consider all the things the algae are producing,鈥 Johnson says. 鈥淲e鈥檙e essentially trying to make oil the waste product, so that it can compete with fossil fuels.鈥

The key is to strike a balance.

One of the MAGIC researchers鈥 goals will be to find the types of algae and the specific growing conditions that result in low-cost oil while providing high-quality protein products.

鈥淭hey鈥檙e not mutually exclusive, but you can鈥檛 optimize everything at once,鈥 Johnson says. 鈥淭here are trade-offs. That鈥檚 where the economic analysis comes in.鈥

Protein extracted from the algae may be used in a variety of ways. MAGIC will study using algae protein as a component of fish, poultry, and swine feed, and as a substitute for current protein products in the food industry, such as whey, which is derived from milk.

鈥淚t turns out that whey is not very environmentally friendly,鈥 Johnson says. 鈥淚f you can replace milk protein with algae protein, you can skip the methane produced by cows, the land use, the water use. Marine algae don鈥檛 use fresh water and don鈥檛 have to compete with traditional crops for arable land, so to the degree to which they can produce food cheaply, they are highly attractive.鈥

Substituting algae protein in animal feed may have human benefits as well. Because algae are high in iron, including algae protein in poultry feed would increase the amount of iron in the meat produced. Chicken is not considered a good source of iron compared with beef, but algae protein products could change that.

Previous work by Johnson and his colleagues at Cornell University has shown that some types of algae produce proteins that can be successfully incorporated into swine and poultry feed.

鈥淥ur work now is to identify better products, and make all those processes more efficient,鈥 Johnson says.

MAGIC will conduct research on the entire process of getting algae products to market, from algae selection and cultivation, to extraction and product preparation, to creation of mass production methods, to techno-economical life cycle analysis.

Each step of the research process will include multiple investigators. 鈥淚t鈥檚 a team effort, and each partner brings their own expertise,鈥 says Johnson.

In addition to 老牛影视, MAGIC will include the University of Hawaii, Archer Daniels Midland, Bentley University, Bucknell University, Cornell University, OpenAlgae, Shell Global Solutions (US) Inc., University of Nordland, The University of Southern Mississippi, and Valicor Renewables.

The mix of university and corporate partners means a mix of environmental and economic goals. But at the end of the day, Johnson says, they all want the same thing: a cost-effective, environmentally-friendly source of fuel and food. 鈥淓veryone鈥檚 committed to finding that balance.鈥
