The Contribution of Nitrate Dissimilation to Nitrate Consumption in narG- and napA-Containing Nitrate Reducers with Various Oxygen and Nitrate Supplies.

ABSTRACT: Nitrate reducers containing narG or napA play an important role in the nitrogen cycle, but little is known about their functional differentiations in relation to environmental changes. In this study, three types of nitrate reducers in the genus Pseudomonas, including strains containing narG (G type), napA (A type) and both narG and napA (GA type), were selected to explore their functional performances under varied nitrate and oxygen concentrations. Their growth characteristics, nitrate consumption, and dissimilatory nitrate-reducing activity were investigated. Growth and nitrate consumption of all three types of strains were generally promoted with increasing oxygen and nitrate concentrations. However, their dissimilatory nitrate-reducing activitie
