    The present study was aimed at enrichment of hydrogen fermentative microflora that can utilize garbage as fermentation substrate. It was shown that stable hydrogen fermentation was performed using enriched microbes from sewage sludge compost. During the enrichment culture, the microflora were analyzed by the FISH method and the PCR-DGGE method. As a result, predominant microbes of hydrogen production were determined to be from the genus Clostridium belonging to a Gram positive Low G+C group. Furthermore, it was supposed that genus Bacillus contributed to the stability of hydrogen productivity from garbage by genus Clostridium. In the batch culture, under pH control at 6.0, it was ascertained that enriched microflora obtained from sewage sludge compost had sufficient hydrogen productivity using garbage, and yielded 2.03mol-H2/mol-hexose. It is supposed that the microflora of sewage sludge compost is effective as inoculum of the hydrogen fermentation system when using garbage as substrate.
