Electron micrograph of Rhodopseudomonas palustris gram-negative purple non-sulfur bacteria. This bacterium is able to switch between four different types of metabolism.

It grows in swine waste lagoons, earthworm droppings, marine coastal sediments and pond water. Although purple non-sulfur bacteria are normally photo-organotrophic, R. palustris  is able to witch between

  • photo-litotrophic,
  • photo-organitrophic,
  • chemo-litotrophic and
  • chemo-organotrophic.

It is able produce enrgy by using

  • light,
  • inorganic compounds, or
  • organic compounds.

It can acquire carbon from either

  • carbon dioxide fixation or
  • any organic compounds.

It is able

  • to produce hydrogen;
  • biodegrade several organic compounds and
  • fix nitrogen.

It is able to live under a wide range of redoxpotention; both under

  • atmospheric and
  • anoxic conditions.

Bioengineers and genetic engineers hope new genes and new gene-level control mechanisms from this bacteria. It is one of the candidates of new biotechnologies too.

Its taxonomic position:

  • Domain: Bacteria
  • Phylum: Proteobacteria
  • Class: Alpha Proteobacteria
  • Order: Rhizobiales
  • Family: Bradyrhizobiaceae
  • Genus: Rhodopseudomonas
