Green sulfur bacteria can use reduced sulfur compounds (hydrogen sulfide, thiosulfate, S°) or H2 as electron donors providing for CO2 photoassimilation (Kondratieva and Gogotov, 1981). Molecular hydrogen uptake occurs with the participation of hydrogenase, the activity of which is found in a number of green bacteria such as Chlorobiurn, Pelodictyon and Chloroflexus (Kondratieva and Gogotov, 1961, 1983). Recently great attention has been paid to the study of structure and functioning mechanism: of these unique biocatalysts as well as to the possibility of their application in native or immobilized states as catalysts of hydrogenation-dehydrogenation reactions. However, in contrast to hydrogenases from chemotrophic and purple bacteria (Kondratieva and Gogotov, 1981, 1983 Colbeau et al., 1983; Serebryakova et al., 1984), the data on the properties of these enzymes from the green bacteria are not abundant.
