Abstract

Sugar supported activities of H₂ production and C₂H₂ reduction were characterized in axenic cell cultures of the cyanobiont Anabaena azollae isolated from the water fern Azolla filiculoides. Fructose was found to be the favoured substrate, enhancing activities in both the light and the dark even at relatively low concentrations of 0·5-1·0 mm. Higher concentrations of sucrose, (10-20 mm) also supported H₂ production and C₂H₂ reduction, while glucose was less effective. Levels of H₂ production were always lower than those of C₂H₂ reduction.
