Digestion/degradation characteristics of porcine intestinal contents and feces inoculated with nitrifying and sulfur bacteria were investigated. Media of contents from the jejunum/ileum, caecum, colon and rectum of 2 Yucatan Microhogs were inoculated with strain cultures of Nocardia nitrificans JCM 4134 and Thiobacilius denitrificans JCM 3869. The former cultures were incubated in a stationary manner (28±1℃, 5d), and the latter under anaerobic conditions (28±1℃, 28d). N. nitrificans had no effect on substrate degradation. Inoculation with T. denitrificans caused decreases in T-N, NO_<3->N and NH_<4->N, and a decrease in SO^<2->_4 in the early stage, in the jejunum/ileum medium. A small decrease in NO_<3->N and an increase in SO^<2->_4 were observed in the colon medium.
