AB  - The microbial structure and kinetic characteristics of the hydrogen producing 
      strains in two fermentative continuous stirred-tank reactors (CSTRs) were studied 
      by controlling pH and oxidation and reduction potential (ORP). The fluorescence 
      in situ hybridization (FISH) tests were conducted to investigate the fermentative 
      performance of Clostridium histolyticum (C. histolyticum), Clostridium 
      lituseburense (C. lituseburense) and Enterobacteriaceae. The experimental results 
      showed that in ethanol-type reactor 1#, the relative abundance of the strains was 
      48%, 30% and 22%. Comparatively, the relative abundance in butyric acid-type 
      reactor 2# was 24%, 55% and 19% with butyric acids and hydrogen as the main 
      products. The kinetic results indicated that the hydrogen yield coefficients YP/X 
      in both reactors were 8.357 and 5.951 l-H2/g, while the coefficients of the 
      cellular yield were 0.0268 and 0.0350 g-Cell/g, respectively. At the same 
      biomass, the hydrogen yield in ethanol-type reactors was more than that in 
      butyric acid reactors. However, the cellular synthesis rate in ethanol-type 
      reactors was low when the same carbon source was used.
