Bielefeld researchers develop hydrogen-producing algae

The working group of Mr Olaf Kruse, of the Faculty of Biology at the University of Bielefeld, arrived in cooperation with a working group of the Institute of Molecular Bioscience of the University of Brisbane. (Australia) to develop a genetically modified alga, mutant of the green alga Chlamydomonas reinhardtii, having an excellent hydrogen production capacity.

This process for developing hydrogen, which has also been patented recently (Patent Nr. WO 2005003024), allows the alga under ideal conditions to produce up to 13 times more hydrogen.
On the basis of these increased hydrogen production rates, Stm6 -tel is the name of the mutated algae- offers remarkable conditions to realize in the future a biotechnology allowing to produce "Bio-hydrogen" from the. sunlight with the help of microorganisms.

Further efforts are still being made in the Brisbane and Bielefeld laboratories, in order to further increase the rates of hydrogen production of the algae through molecular genetic interventions.
