Keynote speakers announcemente - Lars Angenent
Professor Lars Angenent is an Associate Professor in the Department of Biological and Environmental Engineering at Cornell University. He got his BS and MS degrees from Wageningen University, his PhD degree from Iowa State University, worked at the University of Illinois at Urbana-Champaign and the University of Colorado at Boulder as post-doctoral research associates, and at Washington University in St. Louis (Missouri) as an Assistant Professor. Dr. Angenent has published 87 peer-reviewed articles. His recent awards include the Kavli Fellow Award from the U.S. National Academy of Sciences in 2008 and the NSF CAREER award from the US National Science Foundation in 2007. The tenet of his research career has been the study of open cultures of microbial consortia (reactor microbiomes).
One of the most important aspects of Dr. Angenent’s work with open-culture systems is that he integrates them within biorefineries. In the biorefinery concept of converting biomass into fuels, the value of each stream is maximized, and therefore streams are not wasted. Rather, all waste streams are converted to additional biofuels, while simultaneously recycling nutrients and water. His open-culture approach, which he calls the “carboxylate platform” in reference to the formed intermediate or end compounds (i.e., caproate), is integral to biorefineries in that it allows all waste streams, even those formed from traditional single-species systems, to be used. Within the biorefinery concept he has, however, also worked on pure-culture systems, such as syngas fermentation.
Another important aspect that Dr. Angenent has studied is the interactions of bacteria with solid-state electrodes in bioelectrochemical systems. Although, he started with open cultures in this research field to convert wastewater into renewable electric power with microbial fuel cells, it became important to him to also study pure and binary cultures in potentiostatically poised microbial electrolysis cells. One of the main breakthroughs he has accomplished in this area is to use these systems as biocomputing devices (smart biosensors). He is a founding member of the International Society for Microbial Electrochemistry and Technology (ISMET) and serves currently as the president elect.
