Paracoccus denitrificans PD1222

Paracoccus denitrificans PD1222 is a Gram-negative, aerobic bacterium characterized by its bacilli shape and the presence of flagella, although it is non-motile. This organism typically exists in various habitats, indicating its adaptability to different environmental conditions. It can be found as singles, pairs, or clusters, demonstrating a versatile cell arrangement. P. denitrificans PD1222 is a mesophilic organism, with an optimal growth temperature of 25°C, and it operates effectively within a temperature range that accommodates typical mesophilic conditions. The bacterium possesses three replicons and has a double-membrane structure, which is a common feature among Gram-negative bacteria. As a free-living organism, P. denitrificans PD1222 does not exhibit pathogenicity nor does it undergo sporulation. Its ecological role may be significant in biogeochemical cycles, particularly in the nitrogen cycle, where denitrification processes are critical for converting nitrates to nitrogen gas, thus reducing nutrient loading in various environments. This trait underscores the potential of P. denitrificans PD1222 in environmental biotechnology applications, particularly in bioremediation and nutrient management in agricultural systems. The specific accession numbers for genetic studies of this strain are NC_008686.1, NC_008687.1, and NC_008688.1, which facilitate further research into its genomic characteristics and functionalities.
