Total bacteria (triangles) and methanogens (dots) in the four fresh and frozen sample types. Black and grey colours indicate DNA extraction from fresh sample (first extraction) and from 10 days-frozen storage samples, respectively. (A samples input secondary WWTP sludge; B samples output secondary WWTP sludge; C samples input mixed WWTP sludge; D samples output mixed WWTP sludge)
