Among 127 sequences were classified to possess hydrogenase activity, and 26 sequences were matched with carbohydrate-degrading enzymes.

They hope to then use this "minimal" organism as a foundation on which to build new organisms with useful functions, such as ones having cellulase and hydrogenase enzymes that could digest plant material and generate hydrogen.
One photobioreactor utilized hydrogenase activity of the green alga, Chlamydomonas reinbardtii CC-503, cw92 [mt+].
Thus the role of SRB would be indirect through the production of final (sulfides, bisulfides, hydrogen sulfide) or intermediate metabolites (thiosulfates, polythionates) which are corrosive to carbon steel; d) cathodic effects such as cathodic depolarization attributed to SRB hydrogenase of to iron sulfide films would be developed later that passivity breakdown when the corrosion process is in progress; e) the corrosive action of biogenic sulfides can be enhanced by other corrosive ions already present in the medium (e.
Studies on the soil bacterium Azotobacter vinelandii indicate that it yields hydrogen as a by-product of nitrogen fixation; and its characteristics such as high respiratory rates, the ability of expressing anaerobic proteins, and lower growth requirements project the possibility of bridging the diazotroph and hydrogenase.
