AB  - Biological air filters represent a promising tool for treating emissions of 
      ammonia and odor from pig facilities. Quantitative fluorescence in situ 
      hybridization (FISH) and 16S rRNA gene sequencing were used to investigate the 
      bacterial community structure and diversity in a full-scale biofilter consisting 
      of two consecutive compartments (front and back filter). The analysis revealed a 
      highly specialized bacterial community of limited diversity, dominated by a few 
      groups of Betaproteobacteria (especially Comamonas) and diverse Bacteroidetes. 
      Actinobacteria, Gammaproteobacteria, and betaproteobacterial ammonia oxidizers 
      (Nitrosomonas eutropha/Nitrosococcus mobilis-lineage) were also quantitatively 
      important. Only a few quantitative differences existed between the two filter 
      compartments at the group level, with a lower relative abundance of 
      Actinobacteria and a higher relative abundance of the Cytophaga-Flavobacteria 
      group in the back filter compared to the front filter. These results confirmed 
      the N. eutropha/Nc. mobilis-lineage as the main ammonia oxidizers in pig house 
      air filters and allowed first hypotheses for the key organisms involved in odor 
      removal.
