The C.H. inhibition method made the study of denitrification accessible to many more scientists, as shown by the explosive increase in the number of articles about denitrification published since the introduction of the C.H. blockage techniq

Nitrogen is an essential constituent of many biomolecules which are important for life, e.g. amino acids, proteins, or DNA. In the process of nitrogen fixation dinitrogen is reduced to ammonia. This reaction is catalyzed by nitrogenase, a complex mu

In fact, the rapid, dissimilatory reduction to NH. by fermentative bacteria was documented many years ago (see, for example, Woods, 1938). As the limited literature on NO. dissimilation to NH. published before 1988 has recently been reviewed extensively (Cole, 1988; 1989), this ar
