Název v původním jazyce

Comparison of denitrification at low temperature using encapsulated Paracoccus denitrificans, Pseudomonas fluorescens and mixed culture

Popis výsledku v původním jazyce

The aim of this work was to compare denitrification activity of three types of encapsulated biomass containing pure culture of Paracoccus denitrificans or Pseudomonas fluorescens or mixed culture of psychrophilic denitrifiers cultivated at 5 C from activated sludge. The experiments were held with synthetic wastewater containing 50 mg L 1 N-NO3 under the temperature 15, 10, 8 and 5 C. Specific denitrification rates related to the weight of pellets and to the protein content were calculated and the temperature coefficients describing the dependence of denitrification rate on the temperature were determined. Although the mixed culture showed the highest denitrification rate at the temperatures below 10 C, using of pellets containing pure culture is recommended as the mixed culture has slow growth rate and its ctivity at temperatures above 10 C is very low.
