Abstract
In this study, we compared the predominant microorganism after confirming the hydrogen production surface using anaerobic biological degradation in response to the extra concentration of food waste. Showed a 1268.67ml of hydrogen gas production by the highest salinity wastewater was 3g/L, but the food waste salinity was 30g/L of hydrogen gas production lowest 130.73ml. It was able to know that the salinity is the inhibition of the hydrogen production and growth of microorganisms. Result of 16S rDNA PCR-DGGE, elucidated in microorganisms most crowded Clostridium sp. or Klebsiella sp. and microbial contribution of the hydrogen generator is large, Clostridium sp. It was judged.
