✦ Synopsis

Citrobacter intezwtedius was grown in a 14-liter fermenter under batch anaerobic conditions at the following controlled pH values: 5, 5.75, 6.0, 6.5, 7.0, 7.5, and 8.0.

The growth medium was a glucose mineral salts medium with 0.1% ammonium sulfate as the source of sulfur. The optimum pH for HP production was 5.75 and 6.0 which gave a yield of 1.1 moles Hz/mole glucose.

The optimum Hz-productivity was 144 moles Hz per hour at pH 6.0.

## Abstract The influence of initial pH of the culture medium on hydrogen production was studied using sucrose solution and a mixed microbial flora from a soybean‐meal silo. Hydrogen production was not observed at pH values of 3.0, 11.0 and 12.0 but low production was observed at pH values 5.0 and
