Cupriavidus gilardii

Cupriavidus gilardii is a Gram-negative,[4] aerobic, motile, oxidase-positive bacterium from the genus Cupriavidus and the family Burkholderiaceae. It is motil by a single polar flagellum. It is named after G. L. Gilardi, an American microbiologist.[5] The organism was initially identified as Ralstonia gilardii in 1999, renamed Wautersiella gilardii, and most recently moved into the genus Cupriavidus after 16S rRNA gene sequencing revealed it to be most closely related to Cupriavidus necator.[3] Notably, species of this genus are not inhibited by copper due to the production of chelation factors, and may actually be stimulated by the presence of copper.[6]
