High yield single stage conversion of glucose to hydrogen by photofermentation with continuous cultures of Rhodobacter capsulatus JP91

- Photofermentation of glucose was carried out in a single stage continuous culture.
- Yields varied with dilution rate (HRT).
- The highest yield, 9.0 ± 1.2 mol H2/mol glucose was 75% of theoretical.
- There is room for improvement in light conversion efficiency.
