Abstract
En 中文
• Phylogenetic analysis suggests native denitrifiers exist in earthworm gut. • Denitrifiers in the gut were inactivated upon exposure to aerobic conditions. • Higher rate of basal denitrification in live earthworms and fresh casts. • Drilosphere components with N2O:N2 ratio < 1 may completely denitrify nitrate to N2.
