TI  - Exposure to sulfide causes populations shifts in sulfate-reducing consortia.
PG  - 784-91
AB  - The shift in the community structure of a mixed culture of sulfate-reducing 
      bacteria (SRB) at 0.5, 0.75, 1, and 1.5 kg m(-3) sulfide loadings was 
      investigated in an anaerobic continuous bioreactor used for treatment of 
      sulfate-containing wastewater by fluorescence in situ hybridization (FISH), using 
      SRB species-specific and group-specific 16S rRNA-targeting probes. Hybridization 
      analysis using these 16S rRNA-targeted oligonucleotide probes revealed that 
      sulfide was toxic for Desulfonema, Desulfobulbus spp. and the Desulfobacteriaceae 
      group, although it was not toxic for Desulfobacter, Desulfotomaculum, 
      Desulfobacterium spp. or the Desulfovibrionaceae group. On the other hand, only a 
      high concentration of sulfide of 1.5 kg m(-3) was found to be toxic for the 
      Desulfococcus group in the bioreactor. When the sulfide in the feed was 1.00 kg 
      m(-3) the sulfate-reducing capacity of the system decreased, and this decrease 
      was more pronounced when the inlet sulfide was further increased to 1.5 kg m(-3).
