In nitrogen fixing cyanobacteria, there are three enzymes involved in the hydrogen metabolism. Nitrogenase
is an enzyme, which catalyzes the nitrogen fixation from atmospheric N2, to produce ammonia and
concomitantly produce H2 as by produce. The product H2 is taken up to protons and electrons by an uptake
hydrogenase usually found in all nitrogen fixing cyanobacteria. The last enzyme, reversible hydrogenase,
catalyzes the H2 uptake and H2 evolution. This enzyme has also been found in all non-nitrogen fixing
cyanobacteria and in some nitrogen fixing cyanobacteria. Anabaena siamensis was isolated from a rice paddy
fields and shows high capacity to fix atmospheric N2 with subsequent increase of the rice growth rate. This
strain has high potential for hydrogen production. The efficiency of hydrogen production depends on several
factors. Therefore, the objective of this research is to compare the growth and H 2 production performances
of A. siamensis TISTR 8012 under different conditions. It was found that i) Addition of external nitrogen
sources inhibited hydrogen production in A. siamensis TISTR 8012, ii) cell age could affect hydrogen
production rate, ii) the most preferred substrate for hydrogen production in Anabaena siamensis TISTR 8012
was fructose and the environmental conditions such as pH, temperature and light intensity also influenced
hydrogen production in A. siamensis TISTR 8012.
