摘要:

Inorganic pyrophosphatase activity was monitored in sewage samples. The optimum pH for incubation (5h) was within pH 7.5–8.0. Magnesium did not consistently enhance the activity, indicating that the trace metal requirements of the enzyme were sometimes met by cations in the sewage. The activity was present in all samples: high values were recorded in the primary raw sludge and the lowest value was detected in the final effluent.
