      community and hydrogen producing capability in CSTR].

AB  - The start into the types of fermentation was carried out by pH adjustment from 
      4.2 to 6.0 in CSTR system. The process of transforming of hydrogen production and 
      dynamic community of bacteria were studied. The results showed that with the 
      organic load maintained at (33 +/- 1) kg/(m3 x d), there was no change in 10 d 
      for the type of fermentation, the amount of hydrogen does not reduce in 8 d. 
      After 15 d, the system was transformed from the ethanol-based type into butyric 
      acid type and water alkalinity was from 250 mg/L to 2450 mg/L. The use of 
      fluorescence in situ hybridization (FISH) system was in response to the 3 groups 
      of micro-organisms. It was found that in the process of transforming, Clostridium 
      cluster XI increases and Clostridium cluster I and II decreases. 
      Enterobacteriaceae always existed with no change. The microbial growth must be 
      considered with hydrogen production capability. The average hydrogen production 
      rate reached to 23.6 mol/(kg x d) with Clostridium cluster I and II dominated in 
      fermentation reactor.
