Dr. Bruce Rittmann is a contributing author to the article, "Photosynthetic bioenergy utilizing CO2: an approach on flue gases utilization for third generation biofuels," published in Journal of Cleaner Production. The article was coauthored with Center alumni Sara P. Cuellar-Bermudez provides a current perspective on the potential for use of flue gases as a carbon source for microalgae systems.
Dr. Bruce Rittmann is a contributing author on the article "Phosphorus recovery from microbial biofuel residual using microwave peroxide digestion and anion exchange" in Water Research. The article explores microwave peroxide digestion and anion exchange as methods of recovering phosphorus from spent algae for nutrient recycling back to algal systems.
Dr. Bruce Rittmann added to his publications in the field of short-cut nitrification/denitrification with the publication of "Nitrite accumulation from simultaneous free-ammonia and free-nitrous-acid inhibition and oxygen limitation in a continuous-flow biofilm reactor" in Biotechnology & Bioengineering. This is a continuation of a long collaboration with Dr. Wookeun Bae, Dr. Seongjun Park, and Dr. Jinwook Chung to better understand and model short-cut biological nutrient removal.
This month, Swette Center researchers published "Effects of pulsed electric field treatment on enhancing lipid recovery from the microalga, Scenedesmus" in Bioresource Technology. The article discusses how the application of pulsed electric field (PEF) pretreatment technology to Scenedesmus prior to fatty acid extraction led to a 3.1x increase in fatty acids obtained. The article was published by Dr. Yen-Jung Sean Lai, Dr. Prathap Parameswaran, Dr. Ang Li (previous visiting scholar), Maria Baeza (research volunteer), and Dr. Bruce Rittmann.

Dr. Bruce Rittmann, Dr. César Torres, and Dr. Prathap Parameswaran collaborated with colleagues in the Arizona State University's School of Matter, Transport, and Energy to publish "Improved current and power density with a micro-scale microbial fuel cell due to a small characteristic length" in Biosensors and Bioelectronics. The article focuses on using micro-scale microbial fuel cells (MFCs) using a small characteristic length to achieve some of the highest power densities to date. Check it out here!
Several SCEB members and alumni contributed to "Uranium removal and microbial community in a H2-based membrane biofilm reactor," an article published in Water Research. The article focuses on uranium removal using membrane biofilm reactors (MBfRs) and its effects on microbial community. The article also discusses how the presence of sulfate shifts the composition of the microbial community. Authors include Dr. Chen Zhou, Dr. Aura Ontiveros-Valencia, Alex Zevin, Dr. Rosa Krajmalnik-Brown, and Dr. Bruce Rittmann. Check it out here!
Dr. Bruce Rittmann is a contributing author to the aritcle, "Internal loop photo-biodegradation reactor used for accelerated quinoline degradation and mineralization," just published in Biodegradation. The article explores the coupling of UV photocatalysis and biofilm degradation to remove quinoline from wastewater.
"Growth of Desulfovibrio vulgaris When Respiring U(VI) and Characterization of Biogenic Uraninite," authored Dr. Chen Zhou and Dr. Bruce Rittmann, has been published in Environmental Science & Technology. The article provides insights into the uraninite utilization and UO2 production by microorganisms.
