摘要：

Waste water from a distillery was used as the electron donor for photoproduction of hydrogen by Rhodobacter sphaeroides O.U. 001. Hydrogen production by free cells was observed only at 5 and 10% waste water (diluted with tap water) yielding a maximum of 500-mu-l H-2 (in 144 h) at 10% concentration. Calcium alginate immobilization of cells enhanced hydrogen photoproduction two-three fold and hydrogen evolution was observed after varying lag periods at all the concentrations of waste water tested. Semicontinuous culturing of R. sphaeroides was demonstrated in a 3.61 photobioreactor harvesting 11 of culture every day amounting to 2 g dry wt. Hydrogen production was demonstrated for 12 days using immobilized cells with 10% waste water in a 3.61 photobioreactor under light/dark cycles.
