dc.descriptionAbstract: In laboratory experiments, denitrification of nitrate in wastewater proceeded slowly in an acid soil (pH 4.2), but the rate was fast in soils with pH values of 5.5 to 6.8. The rate or denitrification was governed by the carbon source added, with glucose supporting the fastest rate. The rate was somewhat slower with methanol and succinate and was appreciably slower with secondary effluents as the source of supplemental carbon. Charlton loam supported the more rapid denitrification with giucose as a carbon source, but the rate was higher in Windsor sandy loam with sewage as the carbon source. Denitrification in in these soils did not occur at 1°C, and the rate increased with rising temperatures at 7°, 15°, 21-22° and 30°C. Tests of pure cultures of four denitrifying bacteria demonstrated that they needed 0.8 to. 2.0 pg of nitrate-N per cell, whereas the requirement was 1.8 to 8.4 pg of nitrate-N per countable denitrifier cell in soil. In addition, the active denitrifying microorganisms in the test soils were characterized.-
