Fig. 4.2. The oxidation mechanisms of lactate by sulfate in the sulfate-reducing bacteria of Desulfovibrio genus. Circled numbers 1, lactate dehydrogenase (cytochrome c-553) 2, pyruvate-ferredoxin 2-oxidoreductase (CoA-acetylating) 3, phosphate acetyltransferase 4, acetate kinase 5, sulfate adenylyltransferase 6, adenylylsulfate reductase 7, sulfite reductase 8, adenylate kinase. ATP adenosine 5 -triphosphate is also biosynthesized by the catalysis of ATP synthase using the energy liberated by the electron transfer around this part...

Fig. 12a, b. Stimulation of electron transport in two metabolic pathways of D. gigas by ferredoxin. (a) Sulfite reductase activity dependence on Fd II (o) and Fd I ( ) concentration. The values of hydrogen comsumption represent the activity after 12 min and were corrected for the endogenous activity (adapted from Bruschi et al., 8>9))- (b) Pyruvate dehydrogenase activity dependence of Fd II and Fd I concentration. The values determined for hydrogen evolution represent the activity after 12 min (between 8—20 min for Fd I and between 28—40 min for Fd II, due to the existence of a lag period before which Fd II is not active 49h The values were corrected for the endogenous activity (our unpublished data)...
