Trends in Biological Ammonia Production

BioTech, 2023
Food production heavily depends on ammonia-containing fertilizers to improve crop yield and profitability. However, ammonia production is challenged by huge energy demand, the release of ~2% of global CO2, and political instability. To mitigate this challenge, many research efforts have developed bioprocessing technologies to make biological ammonia ...

A two-stage, two-organism process for biohydrogen from glucose [PDF]

, 2006
H2 can potentially be produced in a two-stage biological process: the fermentation of glucose by Escherichia coli HD701 and the photofermentation of the residual medium by Rhodobacter sphaeroides O.U. 001. In a typical batch fermentation, E.
