title: [Coupled biological hydrogen-producing systems: a review].
abstract: Possible ways for combining various biological processes of biohydrogen production are described. Some of these processes are being intensively studied now, whereas others are theoretically feasible, but as yet have not been studied. A special focus is on the factors that influence the efficiency of coupled systems.
