Iowa State awards University (ISU) faculty and staff from the Departments of Agricultural and Biosystems Algae. Various production systems, including Engineering (ABE); Agronomy; flat panel bioreactors, two raceway pond Biochemistry; Chemical and Biological systems, a novel revolving algal biofilm Engineering (CBE); Civil, Construction, and (RAB) system, and various lab-scale reactors Environmental Engineering (CCEE); and located in the BCRF Algae Facility are being Food Science and Human Nutrition (FSHN), used to grow algae. The major focus for these as well as the Bioeconomy Institute (BEI), algal growth systems is removal of nutrients Center for Crops Utilization Research (nitrogen and phosphorus) and toxic metals (CCUR), College of Agriculture and Life from municipal and industrial wastewaters. A Sciences (CALS), and Extension and mobile pilot-scale RAB system was developed Outreach conducted research, teaching, and/or in 2015 to treat wastewater on site at outreach at the BCRF. Private industry users municipalities and industrial processors. of the BCRF included ARGO, Deere & Offsite projects in Fort Dodge and Dallas Company, DuPont Cellulosic Ethanol, Phillips Center, Iowa, and numerous demonstrations 66, and many others. By the end of 2016, the employed this mobile unit in 2016. BCRF had more than 80 full- and part-time users with projects in all available space. Additionally, newer belt designs were added and further research was conducted on The BCRF Advisory Council was established component materials and processes. Projects in the first quarter of 2016. The first meeting with municipal and industrial groups was held May 17–18. The council discussed continued throughout the year to include the BCRF's strengths and weaknesses to help private companies and the City of Chicago, identify short- and long-term goals and (Illinois) water treatment plant. The developed an action plan for future work. researchers led by Zhiyou Wen, FSHN, can produce 1.3 to 4.5 kg of dried algae Research, Education, and Equipment biomass/week in the BCRF facility. A great deal of project activity occurred in the following areas: The diverse algae species grown in the facility are suited for different end uses. Algae with - Algae research and production methods high lipid levels are best for producing - Biochemical research biodiesel, and algae with high protein levels - Biomass feedstock logistics research and good amino acid profiles are used for - Biomass preparation livestock feed. Algae biomass grown on - Biopolymer research wastewater is being studied as an organic fertilizer. 10 Iowa State University, Ag Engineering/Agronomy, Central Iowa, and BioCentury Research Farms ISRF16-16, 30 Biochemical.

This project, the campus and there is the potential for scaling Long-Term Assessment of Miscanthus these up at the BCRF in 2017. In February, a Productivity and Sustainability (LAMPS), is project to grow a single cell microbe was designed to answer several questions about completed in the 500-liter fermentor for an Miscanthus giganteus production. The industrial client. In the fourth quarter, work overarching goal for LAMPS is to answer the began on several week-long fermentations in questions farmers are asking about the 1,000-liter fermentor for another industrial Miscanthus, especially those concerning client. This work continued into 2017. Steam fertility rates and quantifying yields using tube drying testing was completed in August. commercial harvesting equipment. Biomass feedstock logistics. Multiple projects LAMPS has several partners and sponsors to continued in this area in 2016 with the most accomplish its project goals.

The BCRF received numerous bales for observation, stack testing, Biomass preparation. The BCRF prepared ash and moisture content sampling, and other biomass feedstocks for several internal and attribute testing.
