Used in environmental research to quantify nitrous oxide reductase enzyme levels in soil samples, aiding in the study of denitrification processes and nitrogen cycling. Helps assess microbial activity related to N2O reduction, supporting efforts to mitigate greenhouse gas emissions from agricultural and natural ecosystems. Enables researchers to evaluate the effectiveness of soil management practices on microbial functional capacity. Suitable for laboratory use in ecological, agronomic, and climate change studies.
