title: Fluorogenic substrates for the detection of microbial nitroreductases.
abstract: OBJECTIVE
  To synthesize and evaluate fluorogenic substrates for the detection of microbial nitroreductases. These substrates, all based on 7-nitrocoumarin, may be reduced to form fluorescent aminocoumarins.
  
  
  RESULTS
  Thirty pathogenic microbial strains, including both bacteria and yeasts, were examined for nitroreductase activity in a whole-cell assay. All strains readily reduced each of the seven substrates to generate fluorescence, suggesting the widespread presence of nitroreductase activity in pathogenic bacteria.
  
  
  CONCLUSIONS
  These novel substrates facilitate the direct detection of nitroreductase activity and have potential as sensitive indicators of microbial growth.
