The purpose of these pages...
...is to provide information on a bioreactor that produces hydrogen gas in the light. The organism used in the bioreactor to produce hydrogen gas light-dependently is the green alga Scenedesmus obliquus. The bioreactor can be run in the classroom and thus be used to demonstrate the concepts of photohydrogen production. I like to thank Professor Jochen Lehmann from the Fachhochschule Stralsund and the company H-Tec GmbH for providing me with free fuel cells, the company AK-MODUL-BUS Computer GmbH for donating an A/D-converter (see MB-News) & data logger, IDM Computer Solutions for donating UltraEdit, iSilo.com for providing their reader for checking file distributions, and the English Institue of Biology for publishing support!

these pages are intended to supplement the information given in the following articles:
