Abstract

Predictions of seasonal changes in N2O emission that occur in natural estuaries are important to anticipate the future implications of global warming. This study showed the effect of temperature on denitrifying growth and nitrate reduction end product of Comamonas testoteroni isolated from estuarine sediment using both batch and continuous cultures. The μmax values of Comamonas testosteroni grown in anaerobic batch culture were increased with increasing temperature, and the highest μmax was found at 26 oC. Concentrations of nitrate reduced (mg-1 dried weight cells) were higher at low temperature. Concentrations of N2 produced were higher at low temperature and the production of N2 was higher than both NO2- and N2O productions
