Bielefeld Researchers develop algae produce hydrogen

The working group of Dr. Olaf Kruse from the Faculty of Biology at the University of Bielefeld has collaborated with a working group of the Institute of Molecular Bioscience at the University of Brisbane (Australia) to develop a genetically modified algae of the green alga Chlamydomonas reinhardtii, with excellent hydrogen production capacity.

This process of hydrogen development, which has recently been patented (Patent Nr. WO 2005003024), allows the algae 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 alga-offers remarkable 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.
