In vivo emission of dinitrogen by earthworms via denitrifying bacteria in the gut
Article Abstract:
A study aims to determine if earthworms also emit dinitrogen (N2), the end product of denitrification just as they emit nitrous oxide (N2O) as the ingested denitrifiers in the gut appear to be the main source of this N2O. The observations indicate that earthworms emit N2 along with the emission of N2O through the in situ activity of denitrifying bacteria in the gut and nitrous oxide is quantitatively an important denitrification-derived end product under in situ conditions.

Comparative assessment of the aerobic and anaerobic microfloras of earthworm guts and forest soils
Article Abstract:
Experimental studies suggest that aerobic and anaerobic microbial growth potentials of the intestine of worms are similar, while aerobic microbial growth potentials of soil are higher than anaerobic microbial growth potentials. The ratio of microbes exhibiting ability to grow under anaerobic conditions to those grow under aerobic conditions is higher for worm intestine than for the soil. These results support the microbiological nonequivalence of earthworm gut and soil.
