N2 - A mutant plant (Arabidopsis thaliana), sex1-1 (starch excess 1-1), accumulating high starch content in leaves was created to serve as better biomass feedstock for a H 2-producing strain Clostridium butyricum CGS2, which efficiently utilizes starch for H 2 production but cannot assimilate cellulosic materials. The starch content of the mutant plant increased to 10.67mg/fresh weight, which is four times higher than that of wild type plant. Using sex1-1 mutant plant as feedstock, C. butyricum CGS2 could produce 490.4ml/l of H 2 with a H 2 production rate of 32.9ml/h/l. The H 2 production performance appeared to increase with the increase in the concentration of mutant plant from 2.5 to 10g/l. The highest H 2 to plant biomass yield was nearly 49ml/g for the mutant plant. This study successfully demonstrated the feasibility of using a starch-rich mutant plant for more effective bioH 2 production with C. butyricum CGS2.
