AB  - Recent studies using quantitative fluorescence in situ hybridization (FISH) have 
      supported the principle that there are mycolata concentration thresholds, above 
      which foaming is likely to occur. In this study, we surveyed 14 wastewater 
      treatment plants (WWTPs) in the UK, using quantitative FISH, to establish that 
      the principle of a mycolata threshold (2 x 10(6) mycolata cells ml(-1) mixed 
      liquor suspended solids) is an empirical though widely held value. In addition, 
      we designed, optimized and applied probes for members of the less hydrophobic 
      mycolata genera Corynebacterium and Dietzia, to show that these organisms 
      dominated the mycolata populations in two non-foaming WWTPs where the mycolata 
      concentrations were above the threshold value. We propose that the mycolata 
      threshold value is only applicable to hydrophobic members of the mycolata.
