Abstract: | A mixed continuous culture of Clostridium butyricum and Enterobacter aerogenes removed O2 in a reactor and produced H2 from starch with yield of more than 2 mol H2/mol glucose without any reducing agents in the medium. Co-immobilized cells of the bacteria on porous glass beads evolved H2 from starch at 1.3 l/l.h, with H2 yield of 2.6 mol H2/ mol glucose at dilution rate of 1.0 h–1 in a continuous culture. |
