Mathematical model predicts that two species competing for the same limiting resource can not coexist. To understand the coexistence mechanism of multiple species of ammonia-oxidizing bacteria in soil, the two closely related ammonia-oxidizing bacteria were cocultured in liquid and solid media. The different strains become dominant in liquid and solid media. These results suggest that the presence of soil particle and solution facilitate the coexistence of multiple species of ammonia-oxidizing bacteria in soil.
