Cupriavidus necator Cultivation

Cupriavidus necator is a Gram-negative soil bacterium belonging to the class Proteobacteria. Its colony size is 1-2mm. Cupriavidus necator colonies are circular with a raised center and neat edges. The colony is opaque light yellow in color, its surface is smooth and bright, and its texture is viscous.

Cupriavidus necator can be cultured on a nutrient broth medium (NA/NB) containing 3.0g of beef extract, 10.0g of peptone, 5.0g of NaCl, 20.0g of agar (without liquid medium), and 1.0L of distilled water. Its optimum growth pH is 7.0.

Cupriavidus necator is a hydrogen oxidizing bacterium capable of growing at the interface of anaerobic and aerobic environments. It can be easily adapted to both heterotrophic and autotrophic lifestyles. Both organic compounds and hydrogen can be used as energy sources. In addition, Cupriavidus necator can also perform aerobic or anaerobic respiration by denitrifying nitrate and/or nitrite to nitrogen gas. When grown under autotrophic conditions, Cupriavidus necator fixes carbon through the reducing pentose phosphate pathway. The optimum growth temperature is 30°C. More interestingly, Cupriavidus necator produces polyhydroxyalkanoate (PHA) plastic when exposed to excess sugar substrate. PHA can accumulate to around 90% of the dry cell weight. Therefore, it can be used for PHA synthesis.
