The methanotrophs Methylomonas angile (type I) and Methylosinus trichosporium (type II) produced nitrite, nitrate and N 2 O during growth on methane, apparently by heterotrophic nitrification of ammonium. The methanotrophs were also able to consume NO but did not produce it. After incubation of soil from a drained paddy field in the presence of CH 4 the numbers of methanotrophs increased from 10 5 to 10 7 per gram dry weigth. The thus enriched soil showed increased rates of NO consumption while rates of NO production did not change.
