Abstract

The activity of denitrifying methanotrophic bacteria at 11-30 degrees 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 degrees C had an optimum temperature of 20-25 degrees C and that activity dropped as temperature was increased to 30 degrees C. Biomass enriched at 30 degrees C had an optimum temperature of 25-30 degrees 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.
