Davis, 1969

Paracoccus denitrificans, a Gram-negative, coccoid, nitrogen-oxidizing bacterium, formerly known as Micrococcus denitrificans, was first isolated in 1910 by Martinus Beijerinck [1]. It was renamed in 1969 to Paracoccus denitrificans by Davis [2]. Paracoccus denitrificans harbors many features also found in mitochondria and because of this, Paracoccus denitrificans is thought to be a plausible ancestor of the eukaryotic mitochondrion (endosymbiotic theory) [3]. The genome of P. denitrificans was sequenced in 2004 [4].
