Introduction

Biohydrogen is a type of biofuel like others i. Hydrogen can produce by both chemical and biological method. The method, by which the hydrogen is produced biologically by the use of microorganisms, in a bioreactor will refer as Biohydrogen. In simple words, we can say the biological conversion of hydrogen into biohydrogen via microorganisms is known as biohydrogen.

Biohydrogen is a biofuel which is the source of energy that uses living microorganisms for the conversion of hydrogen into biohydrogen via the fermentation and photolysis process in a specialized container or a bioreactor. Year Scientists Discovery Hans Gaffron Discovered the switching of algae between the production of H2 and O2 Ananstasios Malis Discovered the cause of algae to switch from producing H2 by the depletion of sulphur Researchers from the University of Bielefeld Discovered large amount of hydrogen by genetically modifying the single cell Chlamydomonas reinhardtiin Ananstasios Malis Discovered the conversion of solar energy to chemical energy in tax X mutants of Chlamydomonas reinhardtiin.

Among these three generations of biofuel, Biohydrogen comes in the category of third generation biofuel or advanced biofuel. Third generation biofuel has certain advantages over the first and second generation biofuel. The production of the first-generation biofuel has increased the price rates of the food items, whereas the third generation biofuels would not.

Second generation biofuel required more surface area or land for the production of the biofuel, whereas advanced biofuel requires smaller areas for the production and are having the efficiency to capture solar energy 10 times to that of the second generation. There are some unique properties of hydrogen which make it ideal for the production as a biofuel:. The fermentation of Biohydrogen is carried out by the use of microorganisms like bacteria.

The process is either carried out in the presence of light i. This process makes the use of photosynthetic organisms and the additional light source. The organisms used in the photo fermentation carry out the process of photosynthesis by the use of photosystem-I only for the production of hydrogen. For the splitting of water, these organisms not only requires an additional light source but also utilize organic acids like acetic acid to generate hydrogen, by donating its electron.

In photofermentation, we can see in the equation, there is no evolution of oxygen, therefore it is a type of anoxygenic photosynthesis. It is a process which makes the use of carbohydrate as an energy or carbon source.

He is author of over fifty original research publications, twenty-two reviews and book chapters, and numerous abstracts in conference proceedings. He is editor of two books.

    Biological hydrogen production

    He is currently researching the role of metabolite sensing and signalling in the regulation of microbial metabolism, and using metabolic engineering to increase biofuels production. He has strong research interest in the area of applied microbiology and biochemical engineering. His skills are related to the study and development of special processes for the use of microorganisms. This includes fungal spores production by solid state cultivation and their use as protein enzyme reservoir in biotransformations.

    A special interest in phase transfer phenomena coupled to metabolic engineering has to be noticed. It is applied to the design and optimisation of biotransformations involving hydrophobic compounds and carried out in biphasic liquid-liquid media.

    Production of Biohydrogen

    These processes are related both to the food and environment bioremediation areas. His interests have recently be extended to bioenergy, and he is presently co-ordinator of two French research programs on biohydrogen production by anaerobic microorganisms grown on complex media. He is author of about documents including 70 research papers, two patents and 12 book chapters.

    He has supervised 10 PhD students and 20 MSc lab works. He is head of the department of "Study and Development of Processes involving Microorganisms" of the platform for technological development Biotechnology — Material Engineering of Blaise Pascal University and has in charge the team "Solid state fermentations — Biotransformations" of the Chemical and Biochemical Engineering Laboratory in the same university.
