Comparative Denitrification of Selected Microorganisms in a Culture Medium and in Autoclaved Soil1

RESUMO
The denitrifying behavior of selected soil bacteria was compared in a culture solution and in soil that was sterilized by autoclaving. The essential characteristics concerning nitrate reduction and the formation of nitrogenous gases did not change significantly for most bacteria in the two environments. Bacteria whose denitrification product was nitrous oxide evolved the same gas both in soil and in a liquid system, whereas other bacteria formed only nitrogen gas. The validity of laboratory observations in relation to field studies in the domain of denitrification is discussed and evaluated.
