Introduction
Rhodopseudomonas palustris
Rhodopseudomonas palustris belongs to the group of phototrophic non-sulfur purple bacteria. It is a gram negative bacterium commonly found in soil and water. It can survive in both aerobic and anaerobic conditions. It is considered to be a “versatile bacteria” because it is able to fix carbon dioxide to form biomass, convert nitrogen to ammonia and produce hydrogen (hydrogen gas being the byproduct of nitrogen fixation). In the presence of oxygen it catabolizes a range of hydrocarbons from sugars to lignin; however it can switch to photosynthesis in the absence of oxygen. It is increasingly gaining research interest due to its abilities to produce hydrogen and degrade toxic waste. These two have very important applications in bioremediation and alternative energy. [1]
