Our microtiter plate assay is based on the enzymatic reduction of nitrate by dissimilatory nitrate reductase from Pseudomonas stutzeri [EC 1.7.99.4]. Exogenous redox mediators like methyl viologen, methylene blue, and cibachron blue were applied to reduce nitrate reductase. Concentrations of 0.02-0.9 mM nitrate can be detected with +/-6% standard deviation,(More)
