Abstract
A rapid technique was developed for the extraction and preparation of gas samples required for field studies of aquatic denitrification. With this method, the natural atom percent abundance of 15N in air-saturated distilled water was found to be 0.370 ± 0.004 SD. Nitrogen-15 tracer experiments showed that 20% of the nitrate taken up was denitrified in 5 days in lake water samples collected after fall turnover. Under conditions conducive to denitrification, 90% of the nitrate taken up was denitrified in 2 days by pure cultures of a Pseudomonas species.
