Most probable number counts showed that denitrifying species were the numerically predominant NO3- reducing bacteria in the faeces of five methanogenic individuals [about 10(10) bacteria (g dry wt faeces)-1]. In faecal slurries, however, denitrification was a relatively minor route of NO3- dissimilation, since only about 3% of the NO3- was converted to gaseous products, with NO3- being mainly reduced to NO2- and NH4+. When KNO2 was added to the slurries, denitrification became quantitatively… CONTINUE READING
