Researchers at the Biodesign Swette Center for Environmental Biotechnology (BSCEB) and their colleagues have been awarded the 2021 Rudolph Hering Medal from the American Society of Civil Engineers. The prestigious award recognizes the best paper of the preceding year from the Journal of Environmental Engineering.
The research selected for the Hering Medal describes new approaches to one of the thornier issues surrounding the environmental contamination; how to rid ecosystems of a stubborn, pervasive and dangerous chlorinated chemical known as trichloroethene or TCE.
The paper presents the first mathematical model simulating a complex series of chemical interactions in which specialized bacteria reduce harmful TCE to benign end products. The model was then tested using a bench-scale device known as a membrane biofilm reactor in which the successful decontamination of TCE was carried out.
The winning paper was written by Bruce Rittmann, director of the BSCEM center; Rosa Krajmalnik-Brown, director of the newly formed Biodesign Center for Health Through Microbiomes; Chen Zhou, assistant research professor in BSCEB; Yihao Luo, an environmental engineering PhD student in BSCEB and ASU’s Ira A Fulton School of Engineering, as well as Boya Wang and Youneng Tang, both now at Florida State University.
The Rudolph Hering Medal is awarded annually. It was instituted and endowed in 1924 by the Sanitary Engineering Division (now the Environmental & Water Resources Institute) of the American Society of Civil Engineers, in honor of Rudolph Hering, past Vice President of the Society. Hering (1847 –1923) is widely considered the founder of the field of modern environmental biotechnology.
