Bielefeld Researchers develop algae produce hydrogen

Mr. Olaf Kruse The working group of the Biology Faculty of the University of Bielefeld, succeeded in cooperation with a working group of the Institute of Molecular Biosciences (Institute of Molecular Bioscience) of the University of Brisbane (Australia) to develop a genetically modified algae mutant of the green alga Chlamydomonas reinhardtii, which has excellent capacity for producing hydrogen.

This hydrogen development process, which has also recently been patented (Patent Nr. WO 2005003024), allows algae in 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 alga-offers outstanding conditions for future biotechnology to produce "Bio-hydrogen" from the sunlight using microorganisms. Additional efforts are still being made in the Brisbane and Bielefeld laboratories to further increase algal hydrogen production rates through molecular genetics interventions. The construction of first prototypes of bioreactors in cooperation with biotechnologists is planned again this year.
