Abstract: | Summary The NAD(P)H fluorescence ofPseudomonas aeruginosa dropped sharply upon addition of nitrate to an anaerobic culture, indicating that denitrification is not limited by mass
transfer of nitrate through cell membrane to reach nitrate reductase. The effect of added nitrate concentration on fluorescence
drop followed a typical saturation kinetics. The maximum specific denitrification rate under the studied condition was found
to be 0.26±0.05 g NO
