✦ Synopsis

Production of H 2 from glucose by an anoxygenic phototrophic bacterium (Rhodobacter sphaeroides), a cyanobacterium (Synechococcus cedrormn) and a heterotrophic bacterium (Pseudomonas tluorescens) was tested individually and in mixed cultures of various combinations in light. H 2 production was maximal with a mixed culture of R. sphaeroides and P. tluorescens, which could be further enhanced by immobilization of the bacteria in alginate gel. Inhibition of H2 photoproduction was observed in a mixture of S. cedrorum and P. tluorescens and a co-culture of all the three organisms.
