Bacterium Breaks Down Ammonium in Sewage and Runoff Without Oxygen

Wetlands are one of nature's plans for treating water. Home to a host of different microbes, riparian wetland soils play matchmaker to nutrient-rich runoff and bacteria that feast on nutrients and other environmental toxins. Princeton University researchers have discovered one such bacterium—Acidimicrobiaceae bacterium A6—that can break down ammonium, part of both fertilizer and sewage runoff, without oxygen. This ability could mean wastewater treatment without expensive aeration machinery. Peter Jaffé , Princeton's William L. Knapp '47 Professor of Civil Engineering and a professor at Princeton's Andlinger Center for Energy and the Environment , corresponded with EM about the latest research . Dr. Jaffé and his team first published on A6 in 2015.

Monitoring and Tracking Ocean Microbes with LRAUVs

In March and April of 2018, researchers from the University of Hawai'i at Mānoa (UH Mānoa) and the Monterey Bay Aquarium Research Institute (MBARI) deployed a small fleet of long-range autonomous underwater vehicles (LRAUVs) in the waters of the Pacific near Hawaii. These LRAUVs automatically collect and archive samples of seawater, enabling scientists to study and track ocean microbes with a level of detail that is unprecedented. Chasing eddies The team who undertook the expedition on the research vessel Falkor was hoping to survey and track Mesoscale eddies within the North Pacific Subtropical Gyre (NPSG) using a suite of oceanographic instruments.

Toxic Chemicals in Plastic Pollution Littering Freshwater Habitats

When we consider the glut of plastic rapidly accumulating all over the world , it's easy to see the problem of pollution and disposal of substances that don't biodegrade. However, it's not always as apparent to us that plastic pollution also means a growing number of toxic chemicals in the environment, many of which can be harmful to ecosystems. Plastic polymers and the products made from them are wildly diverse as to chemical properties, composition, and range of potential applications, although most plastics are made from petrochemicals. Throughout the very long lifespan of any given plastic product, the material may release various hazardous substances .
