Abstract

The stability of biological H₂ production and microbial diversity by anaerobic sludge treated chloroform with different concentrations were investigated in this work. Taking into account the cumulative H₂ production, H₂ percentage, maximum H₂ production rate, H₂ yield and substrate utilization efficiency together, 0.050% of CHCl₃ concentration was found to be appropriate for enhancing anaerobic H₂ production. The repeated batch tests revealed a good stability of H₂ production with the inocula treated by chloroform at different concentrations. Denaturing gradient gel electrophoresis (DGGE) analysis demonstrates that CHCl₃ showed desirable selective inhibition on methanogens, rather than H₂-producing bacteria. The favorable microbial communities for fermentative H₂ production by anaerobic sludge were uncultured bacterium clones nbt176c01, Janthinobacterium sp.7, Megasphaera paucivorans strain VTT E-03234, Clostridium cellulosi strain D3 and Clostridium sp. HPB-4.
