Antibiotic resistance is fueled by antibiotics released into the environment through animal manure. This research shows that aerobic biofilm carrier reactors can degrade up to 92% of antibiotics in manure. Improved manure treatment can reduce environmental reservoirs of resistance and help preserve antibiotics as effective treatments for bacterial infections.

This research tackles nitrous oxide emissions from agricultural soils, a major driver of global warming. By modifying manure application practices—mixing manure into soil or adding biochar—the study enhances soil microbes that consume nitrous oxide, reducing emissions by 60–70% through improved microbial balance and reduced gas escape.
