- •
Denitrifying methanotrophic bacteria were enriched from municipal wastewater sludge.
- •
The maximum denitrification rate at 20 °C was similar to maximum rates at 30 °C.
- •
After 1–2 years consumption rates decreased; the cause for this is unknown.
- •
Results indicate higher rates may be achieved by addition of low amounts of copper.
- •
Increased rates may also be achieved at shorter hydraulic retention times.
