Microbial Community Engineering for Clean Water, Bioenergy Generation, and Resource Recovery
Abstract
Microbial bioprocesses are a cornerstone of our urban water quality control infrastructure. They are also increasingly viewed as a crucial platform in the emerging circular bioeconomy to recover valuable resources (e.g. clean water, energy, nutrients, biomaterials, bio-based chemicals) from organic carbon and nutrient rich societal waste streams. Despite their environmental and economic importance, surprisingly little is known about the nature or “design rules” of the complex microbial communities that underlie emergent function in these bioprocesses. In this talk, I will detail of our efforts to deepen understanding of diversity, metabolic versatility, community assembly mechanisms, and ecological selection pressures in the microbial world in order to inspire novel resource efficient environmental bioprocesses, with a particular focus on nitrogen (N) and phosphorus (P) removal and recovery. Our efforts in this area address the grand challenge of preventing nutrient pollution responsible for a vast array of environmental and public health problems, including eutrophication of nutrient limited water bodies, greenhouse gas (nitrous oxide) production, and direct adverse effects to human health (e.g. methemoglobinemia caused by nitrate.). First, I will present evidence that newly discovered complete ammonia oxidizing bacteria (comammox) are a crucial but previously unrecognized biocatalyst for high rate and energy efficient nitrification at water resource recovery facilities. However, our work also shows that comammox may impede ecological selection for anaerobic ammonia oxidation (anammox) in mainstream shortcut N removal bioprocesses via competition for metabolic intermediates. I will then introduce an emerging paradigm in which societal waste streams are viewed not as costly energy sinks but as feedstocks for energy or resource recovery. I will present efforts in line with this paradigm towards development of a novel mixed-culture bioprocess for microbial production and capture of nitrous oxide as a source of bioenergy, with concurrent recovery of P as a fertilizer. Genome-resolved ‘omics’ analyses of the underlying microbiome in this bioprocess have revealed a surprisingly high prevalence of incomplete denitrification pathways, with far reaching implications for understanding microbial nitrous oxide production and metabolic division of labor in both engineered and natural systems. Finally, I will conclude by highlighting our efforts to elucidate the ecology and genomic context of emerging “genetic contaminants” in the form of antibiotic resistance genes in engineered bioprocesses. Taken together, these results demonstrate the utility of coupling fundamental microbial ecology research to novel bioprocess development.
Biography
George Wells is an Assistant Professor in the Department of Civil and Environmental Engineering at Northwestern University, where he directs the Environmental Biotechnology and Microbial Ecology Laboratory. His primary research interests are resource and energy recovery from wastewater and other urban “waste” streams, microbial nitrogen and phosphorus cycling and shortcut biological nutrient removal processes, microbial ecology of engineered and impacted natural systems, biofilm structure-function relationships, and microbial greenhouse gas production. George received his B.S. in Chemical Engineering and B.A. in Environmental Engineering from Rice University in 2004. After a short period working at BP Chemicals in Naperville, Illinois, George joined the Department of Civil and Environmental Engineering at Stanford University, where he completed his MS (2006) and PhD (2011) under Dr. Craig Criddle and Dr. Chris Francis. Prior to joining Northwestern University in the fall of 2013, George spent nearly 2.5 years as a postdoctoral scholar under Dr. Eberhard Morgenroth at Eawag- the Swiss Federal Institute of Aquatic Science and Technology (near Zürich, Switzerland).

Jimmy Quon Lecture: Valorizing Gas Streams Containing CO2 and CO- Bruce Rittman
McCormick - Civil and Environmental Engineering (CEE)
2:00 PM A230, Technological Institute
EVENT DETAILS
Abstract: Carbon dioxide (CO2) is the most important greenhouse gas, and carbon monoxide (CO) is acutely toxic. Release of these gases must be halted. One promising approach is microbiological valorization of CO2 and CO in off-gas streams. Valorization means converting the CO2 or CO to valuable organic compounds that are feedstock for the chemical and energy industries. This talk describes two distinctly different examples of valorization. The first example is valorizing the CO2 in digester biogas using photosynthetic microalgae. The benefits are to generate more methane (CH4) while converting the biogas (~65% CH4) to higher-value biomethane (>97% CH4). The second example is conversion of syngas (a mixture of CO, CO2, and hydrogen (H2)) to organic acids and alcohols using CO-fermenting and chain-elongating bacteria.
Bio: Dr. Bruce E. Rittmann is Regents Professor of Environmental Engineering and Director of the Biodesign Swette Center for Environmental Biotechnology at Arizona State University. His research focuses on the science and engineering needed to “manage microbial communities to provide services to society.” Services include generating renewable energy, cleaning water and soil, and improving human health. Dr. Rittmann is a member of the National Academy of Engineering; a Fellow of AAAS, WEF, IWA, AEESP, and NAI; and a Distinguished Member of ASCE. Dr. Rittmann was awarded the first Clarke Prize for Outstanding Achievements in Water Science and Technology from the NWRI, the Walter Huber Research Prize and the Simon Freese Award from ASCE, the G.M. Fair Award from AAEES, the Perry L. McCarty/AEESP Founders Award, and the Camp Applied Research Award from WEF. He is the co-winner of the 2018 Stockholm Water Prize. Dr. Rittmann has published over 880 journal articles, books, and book chapters, and he has 25 patents. With Dr. Perry McCarty, Dr. Rittmann co-authored the textbook Environmental Biotechnology: Principles and Applications (McGraw-Hill Book Co.), which is now out in its second edition.
