Molybdenum Limits Microbes’ Ability to Remove Harmful Nitrate from Soil

The Oak Ridge Reservation is contaminated with acidic, high-nitrate-and high-metal substances. Microbes in this environment can use molybdenum to remove nitrate, but the low concentration of molybdenum at Oak Ridge limits how much nitrate the microbes can remove. Two studies examine why molybdenum is limited and the mechanisms some microbes use to survive these conditions.

Restoring wetlands near farms would dramatically reduce water pollution

Study examines the positive effects of wetlands on water quality and the potential for using wetland restoration as a key strategy for improving water quality, particularly in the Mississippi River Basin and Gulf of Mexico regions
