The activity of denitrifying methanotrophic bacteria at 11-30 °C was assessed in short-term experiments. The aim was to determine the feasibility of applying denitrifying methanotrophic bacteria in low-temperature anaerobic wastewater treatment. This study showed that biomass enriched at 21 °C had an optimum temperature of 20-25 °C and that activity dropped as temperature was increased to 30 °C. Biomass enriched at 30 °C had an optimum temperature of 25-30 °C. These results indicated that biomass from low-temperature inocula adjusted to the enrichment temperature and that low-temperature enrichment is suitable for applications in low-temperature wastewater treatment. Biomass growth at ≤20 °C still needs to be studied.
在短期实验中评估了11-30℃下反硝化甲烷氧化菌的活性。目的是确定在低温厌氧废水处理中应用反硝化甲烷氧化菌的可行性。本研究表明，在21℃下富集的生物量的最适温度为20-25℃，当温度升至30℃时活性下降。在30℃下富集的生物量的最适温度为25-30℃。这些结果表明，来自低温接种物的生物量适应了富集温度，并且低温富集适用于低温废水处理。≤20℃时生物量的生长仍有待研究。
