Technology of microbiological conversion of organic cellulose waste into electricity through the intermediate formation of bio-hydrogen

Screening of microorganisms capable of degradation of cellulose waste to hydrogen was held, also a basis technology for the extraction and use of hydrogen was created. Classical microbiological methods were used to screen. Technology is non-porous polymer membranes were used to extract hydrogen from the culture fluid. Hydrogen is continuously oxidized to form electricity, using innovative technology of enzyme electrode based on hydrogenase. Several high-yield microbiocenosis were selected in the work, the possibility of intensifying the process of microbial hydrogen formation from 20 mM (H2)·l–1·h–1 to 68 mM (H2)·l–1·h–1 due to application of membrane technology shows as well as the possibility of using enzyme fuel electrode for hydrogen oxidation. Maximum output amounted up to 250 mkVt/sm2. It is shown that it is possible to use both technologies for generating electricity and clean hydrogen.
