• ENVIRONMENTAL FACTORS AFFECTING NITRIFIER INHABITATION IN A RIVERHEAD AREA

抄録

The habitat distribution of nitrifier in a riverhead area was kinetically examined by nitrification activity batch test using sampled soil. The kinetic estimation showed that the soil with higher carbon content had lower nitrifier content. On the other hand, the soil with higher carbon content possessed higher content of ubiquinone which was an indicator of aerobes. Nitrate was not detected in the soil with higher carbon content, while it existed in hillslope whose soil had lower carbon content. Therefore, it was inferred that the competition of oxygen between heterotrophs and nitrifier occurred. Since nitrifier had lower growth rate than heterotrophs, nitrifier was presumably difficult to survive in the soil with higher carbon content.
