  • Where are anaerobic bacteria found?
  • Anaerobic bacteria were widely present both in the sewage and in the air at workplaces in the wastewater treatment plant, reaching the highest concentrations in closed spaces.
  • Are aerobic bacteria in wastewater treatment plants anaerobic?
  • Although there is no similar data for anaerobic bacteria in the scientific literature, the results for aerobic bacteria in the wastewater treatment plant seem to confirm that, in this range of aerodynamic diameters, the concentration of microorganisms in the air is the highest (Li et al. 2013 ).
  • Which bacteria are delivered to the wastewater treatment plant (WWTP)?
  • A substantial part of the anaerobic bacteria is delivered to the wastewater treatment plant (WWTP) by the sewage network. In the recent study of Liu et al. ( 2015a ), 18 species of Longilinea, Georgenia, Desulforhabdus, Thauera, Desulfuromonas and Arcobacter genera were identified in the sewerage system.
  • What is the average concentration of anaerobic bacteria in sewage?
  • The average concentration of anaerobic bacteria in the wastewater samples was 5.49 × 10 4 CFU/mL (GSD = 85.4). The highest values were noted in raw sewage flowing into the treatment plant (P1—1.77 × 10 6 CFU/mL), and the lowest in the leachate from the digested sludge (P3—185 CFU/mL).
