The aerobic hydrogen bacteria, generally known as Knallgas-bacteria", are not phototrophic and are very easy to grow. The formation of cell material from hydrogen, oxygen, and carbon dioxide can be summarized by the following equation ... 

Most hydrogen bacteria are rodlike and are known under the generic name Hydrogenomonas (Fig. 1). Several strains were given specific... 

The enrichment conditions can be, and have been modified in many ways. Temperature, pH-value, salt concentration etc. have been varied. Furthermore, the direct plating technique on solid media has been employed to isolate hydrogen bacteria. 

Hydrogen bacteria are facultative chemoautotrophs they grow as well or at an even higher rate under heterotrophic conditions. Fructose is the only carbohydrate which many strains such as Hydrogenomonas eutropha and strain H16 can utilize as a substrate. Most strains are able to grow with organic adds and amino acids. Some strains are also able to decompose aromatic compounds, purines, and pyrimidines. 

For the growth of hydrogen bacteria under autotrophic conditions in submerged mass culture, the nutrient solution described above may be used only ammonia may become growth-limiting and an additional...
