Application of Immobilization Technology on Enhancing Hydrogen Production by Photosynthetic Bacteria

Hydrogen is a clean and effective energy. Development of hydrogen production technologies is one of the research focuses currently. Application of new-type technologies and materials on biological hydrogen producing is a research emphasis to enhance hydrogen production and promote its engineering application. The latest progress in research on photo fermentative hydrogen production by immobilized photosynthetic bacteria is reviewed. The fundamental of immobilization, progress of its application and impact factors on hydrogen production are summarized. Three immobilization methods including entrapment, suspended carrier and fixed biofilm are discussed in detail, mainly from the aspect of their effects on photo fermentative hydrogen production. New materials which have been worldwide utilized on immobilization are introduced. An outlook on research direction and focuses are also proposed.
