The enzyme hydrogenase isolated from the sulphate reducing anaerobic bacterium Desulfovibrio gigas was encapsulated in reverse micelles of AOT–water–isooctane. The enzyme ability to consume molecular hydrogen was studied as a function of the micelle size (given by Wo = [H2O]/[organic solvent]). A peak of catalytic activity was obtained for Wo = 18, a micelle size theoretically fitting the heterodimeric hydrogenase molecule. At this Wo value, the recorded catalytic activity was slightly higher than in a buffer system(Kcat = 169.43 s−1 against the buffer value of 151 s−1). The optimal buffer used to encapsulate the enzyme was found to be imidazole 50 mM, pH 9.0. The molecular hydrogen production activity was also tested in this reverse micelle medium.

The work presented in this thesis describes the functional characterization of hydrogenases in the overall energy metabolism of the sulfate reducing bacterium Desulfovibrio gigas. With the complete annotation of the D. gigas genome, we were able to verify that only the two previously described hydrogenases are present in this organism, the periplasmic [NiFe] HynAB and the cytoplasmic membrane-bound [NiFe] Ech.(...)
