  • Title: Comparison of dentrification by Paracoccus denitrificans, Pseudomonas stutzeri and Pseudomonas aeruginosa.
    Author: Błaszczyk M.
    Journal: Acta Microbiol Pol; 1992; 41(3-4):203-10. PubMed ID: 1284849.
    Abstract:
    The course of denitrification of nitrate, nitrite and both compounds together by static cultures of Paracoccus denitrificans, Pseudomonas stutzeri and Pseudomonas aeruginosa was studied. These strains represent three different types of denitrification: 1. reduction of nitrate to gaseous nitrogen without accumulation of nitrite (P. denitrificans); 2. partial accumulation of nitrite in growing cultures during reduction of nitrate to gaseous nitrogen (P. aeruginosa) and 3. two-phase denitrification that includes reduction of nitrates at the very beginning of the process, and then, after depletion of the former, the reduction of nitrates to gaseous nitrogen (P. stutzeri). These observations differ from the results reported in the literature and possible reasons are discussed.
