Fermentative Biohydrogen Production by Mixed and Pure Bacterial Culture: Designing of Processes and Engineering Control

In this paper the research about applied bio-hydrogen production engineering is introduced. The advantages, disadvantages and characteristics of bio-hydrogen production systems and some technical issues on anaerobic fermentative bio-hydrogen producing systems will be discussed and focused on the schematic processing, designing strategies and engineering control of fermentation parameters and also the technical means to increase the evolved hydrogen and hydrogen evolution rate. The technology of bio-hydrogen production based on ethanol-type fermentative theory has been established. The mixed continuous culture and pure batch culture processes were proposed for hydrogen production.
