Hydrogen from Sunlight

Ning Xiao

Research student Ning Xiao has just returned from Brazil where she presented her work at the 16th International Biotechnology Symposium and Exhibition, Biotechnology for the Development of a Green Economy

Together with Dr Krishnaa T. Mahbubani and Prof Nigel K. H. Slater, Ning’s presentation has described the work about using a photosynthetic bacterium as a biocatalyst for hydrogen production.

Diminishing fossil fuel reserves, climbing energy demand, and growing environmental concerns have increased the emphasis on clean renewable energy. Today, there is an unprecedented interest in biofuel as an alternative fuel, particularly in the form of biologically generated hydrogen. Rhodopseudomonas palustris, a purple non-sulphur bacterium, is known to produce good yields of hydrogen during anaerobic photoheterotrophic growth. It could act as a source and the biocatalyst for continuous and economical hydrogen (H2) production.

Ning has described the process further in this video.
