Optimization of Denitrifying Bioreactor Performance with Agricultural Residue-Base Filter Media

    The United States Department of Agriculture-Agricultural Research Service (USDA-ARS) conducted a research project to investigate the performance of agriculturally derived residue materials in bioreactors. This included a comparison of the materials to wood chips at two temperatures, 59 and 35°F (15 and 2°C), identified as Run 1 and Run 2, respectively, in continuous flow column experiments. The investigation measured nitrate removal, microbial abundance and dissolved nitrous oxide gas. In a… Continue Reading Optimization of Denitrifying Bioreactor Performance with Agricultural Residue-Base Filter Media

    The Agricultural Utilization Research Institute (AURI) offers a comprehensive program to catalyze and support small businesses and entrepreneurial innovation in value-added agriculture: AURI’s Entrepreneur in Residence (EiR) Program. AURI believes this program is a critical component in the success of its programs and mission.

    Moving from ideation to proof of concept and early demonstration is a costly but critical step in product development. The EIR Program intends to make this step more accessible by providing qualified entrepreneurs with access to laboratory facilities and support through a period of residency at AURI’s facilities. Such access allows the Entrepreneurs in Residence to use and benefit from specialized equipment and facilities that may otherwise be out of reach or prohibitively expensive.

    AURI’s EiR Program is also designed to provide support to entrepreneurs in their efforts to obtain non-dilutive funding through grants from Federal, State, and other public or private entities. For example, some research and development grants may not allow financing for laboratory space and facilities or require the grantee to provide matching funds. The AURI EiR program provides qualified entrepreneurs with a source of in-kind matching funds, increasing the likelihood of a grant award.

    Any IP developed under the EiR program will be assigned to the Entrepreneur, thus leaving them unconstrained in pursuing further commercialization efforts after the EiR residency has been completed.

    Participation in AURI’s EiR Program
    The EiR program is open to single proprietors, partnerships, or limited liability corporations organized under the law of Minnesota or with a principal place of business in Minnesota. AURI expects the beneficiaries of the EiR program to be mainly pre-revenue small or individual businesses, although different situations may be considered to the sole judgment of AURI.

    To optimize the use of limited laboratory and staff resources, AURI will limit the number of concurrent EiR projects with a preference for residencies not more than 8 months in duration. To be eligible for AURI’s services, program candidates must benefit Minnesota’s agricultural sector and agricultural products, demonstrate the potential for positive impact on Minnesota’s economy and be commercially viable. In addition, candidate’s products or processes must fit within one of AURI’s focus areas:

    • Food,
    • Coproducts,
    • Biobased Products,
    • Renewable Energy.

    EiR candidates must also demonstrate the capacity and intent to continue commercializing their idea upon residency completion. Finally, EiR candidates must provide a plan of work and business plan with a budget that reflects their ability to support the project during residency and their strategy to continue the project funding afterward.

    The EiR program is offered in partnership with Minnesota State University, Mankato’s Mainstreet Businesses Focused on Food and Agriculture initiative (MBFFA).

    Navigating Challenges: Minnesota’s Food and Agriculture Manufacturers and Processors Supply Chains

      This report illustrates the impact of the novel Coronavirus Disease (COVID) on supply chains for Minnesota food and agriculture manufacturers and processors. A collaboration providing services to Minnesota food and agricultural economic sectors wanted to better understand the supply chain effects of COVID, the resulting pain points and what may be needed to help identify potential new services, resources and supportive actions that would improve supply chain resiliency for Minnesota businesses.
