Abstract
An ISO-NO sensor was used for continuous measurement of nitric oxide r elease and consumption during denitrification. The sensor was selectiv ely responsive to NO in the presence of other denitrification-associat ed nitrogen oxides. Evolution of NO signal was coupled with the metabo lism of NO2-. The immobilized Pseudomonas stutzeri seems able to to re strict its physiological NO pool to less than 100 nM (about 2 x 10(-5) mole/mole of the NO3- or NO2- reduced), a level being one hundredth o f the concentration required to inactivate a population in 45 min.
