Title:
MICROBIAL PROCESS FOR PRODUCING HYDROGEN
Document Type and Number:
WIPO Patent Application WO/2001/002595
Kind Code:
A1
Abstract:
In the production of hydrogen with the use of microorganisms, the production of hydrogen by culturing a microalga under light and aerobic conditions and/or the production of hydrogen with the use of a photosynthetic bacterium under light and anaerobic conditions are performed by using a transparent tower-type air lift culture tank. Hydrogen can be more efficiently produced by using the above tank having a double cylindrical structure and provided with a helical flow promoter.
