Taxonomic Study of Paracoccus denitrificans NOKHAL, TALAAT-H. and SCHLEGEL*, HANS G.,, 33, 26-37 (1983), doi = https://doi.org/10.1099/00207713-33-1-26, publicationName = Microbiology Society, issn = 1466-5026, abstract= Isolates of Paracoccus denitrificans were obtained from various habitats by enrichment in a mineral medium, using molecular hydrogen as the hydrogen donor and nitrate as the hydrogen acceptor. A total of 11 strains were compared with the following three reference strains: P. denitrificans Stanier 381T (type strain) (= DSM 65T = ATCC 17741T), Morris (= DSM 413 = ATCC 19367), and Vogt (= DSM 415). A computer analysis based on 235 characters indicated that the strains clustered into subgroups. Deoxyribonucleic acid-deoxyribonucleic acid homology determinations confirmed this suggestion. A formal description of the species is presented, and the taxonomic position of P. denitrificans is discussed., language=, type=
