Welcome to Dr. Bo Hu’s Bioprocessing Group website

Dr. Bo Hu's research group focuses on the development of bioprocessing technologies to convert agricultural residue and waste materials to value-added chemicals and biofuels. Research areas include biomass utilization, industrial fermentation, waste management and treatment. The research team has established several new cultivation methods, such as solid state cultivation, pelletized cultivation of fungi and algae, and cultivation of lichen biofilm. We have adopted several advanced technologies to assist our research; for example, 16s rRNA microbial community analysis using high-throughput pyrosequencing and fungal identification through internal transcribed spacer (ITS) sequences. Several of these platform technologies are notably unique and innovative and have received international attentions in the field. Over the past years, we received funding for the following research topics:

  • Co-culture of filamentous fungi and microalgae to form pellets and lichen biofilm
  • Phosphorus removal from waste and animal feed by microbial or electrochemical approaches,
  • Phosphorus and sulfur removal and recycling by microbial, chemical, and electrochemical approaches
  • Understanding the recent swine manure foaming in the Midwest
  • Develop processes to improve the value of animal feeds



Dr. Xiao Sun joined the group to work as a Postdoc. Welcome Xiao!



Leif van Lierop has joined our group as a PhD student. Welcome Leif!



Tanner re-joins our research group to work on his PhD. Welcome back!



Our group received funding supports from National Science Foundation to work on animal feed productioins from corn ethanol coproducts.

Prof. Bo Hu and his team have been working on modifying septic systems to improve the romoval of pollutants such as carbon and phosphorus. The research has been focused on design, operation and optimisation of microbial electrochemical septic tanks at lab-scale and pilot-scale. This is a short video about the Pilot scale experiments carried out at the Metropolitan Wastewater Treatment Plant in St. Paul.


Cris succesfully defended his Ph.D. research. His dissertation topic was "Value Addition and Nutrient Recovery from Ethanol Coproducts" and his committee members were Dr. Hu, Dr. Ruan, Dr. Tschirner, and Dr. Urriola (Animal Science/UMN). 

Dr. Hu and Cris attended the MnDRIVE Evening of Discovery event at Minnesota History Center.
UMN president, Dr. Eric Kaler, stopped by the poster and we had a good talk on phytate chemistry.
Thanks to MnDRIVE for the continuous support to our research!

Dr. Hu, Carlos, Hongjian, and Ara attended the MnDRIVE Mini Symposium on Bioremediation at Barr Engineering in Minneapolis. They presented their work on the development of novel septic systems, electrochemical systems to treat wastewater, and the utilization of artificial lichens to add value to different wastewaters.

Dr. Hu, Ara, Yanmei and Cris attended the MN Ag Expo in Mankato and presented a poster on yeast genetic engineering to improve DDGS amino acid profile.
Thanks to MN Corn Growers Association for the continuous support to our research!


Laura, Cris, and Tanner are finalists for the DOW Sustainability Innovation Student Challenge Award 2016. Tanner's and Cris's proposal focused on the Application of Artificial Lichens in Agricultural and Feed Systems and Laura's proposal was to develop an Economical Production of Sustainable Fertilizers from Animal Manure. Congratulations to Laura and her runner-up prize! Bo Hu - News
