It is an oxide of nitrogen. At room temperature, it is a colorless, non-flammable gas, with a slightly sweet odor and taste. N2O is produced naturally by microorganisms in soil through various types of nitrification and denitrification processes. (Wikipedia) Nitrous oxide production by Escherichia coli seems to result from the reduction of nitrite (NO2-) by nitrate (NO3-) reductase.
