The other requirement is to monitor the pressures in the recycle loop, as well as in the nitrifier tubes, and carry out automatic shutdown procedures in the case of off-nominal values.
We also measured nitrifier populations and activity; the C, N, and [[delta].sup.15]N of the light fraction and heavy fraction organic matter pools; microbial N (chloroform fumigation-extraction); and field net N tr ansformations during the 1994-1995 growing season.
These carbon eating heterotrophic bacteria grow 100 times faster than autotrophic nitrifiers. The high growth rates and associated oxygen demand suffocate nitrifiers buried deeper in biofilms by blocking available oxygen, which causes death and biofilm sloughing from reactor surfaces.

(2006); the authors found that this response was lacking in grassland soil with naturally high rates of nitrifier activity.
We were able to assess whether there was any nitrifier activity under the microaerobic conditions by first calculating the ratio of [N.sub.2]O production rates under anaerobic vs.
Recently, [N.sub.2]O production in soils has also been ascribed to nitrifier denitrification.
