Table 3 Role proposed for the Chloroflexi microorganisms in the different reactors according to the metabolic function detected in the MAGs
Reactor | Process | Wastewater composition | Metabolic role | MAGs harvoring this function | Structure role in biomass |
|---|---|---|---|---|---|
MO | Anaerobic treatment for C removal | Polysaccharides, proteins, carbohydrates | Hydrolysis of complex polymers from the wastewater by fermentation, EPS degradation | All MAGs | Granules structure |
RH | Aerobic treatment for C-removal | Polysaccharides, proteins, carbohydrates | Hydrolysis of complex polymers from the wastewater by fermentation or aerobic respiration, EPS degradation | All MAGs | Flocs structure |
S and AM | N-removal by anammox | Ammonium and nitrite | EPS and cell debris degradation | All MAGs | Anammox granules structure |
Reduction of nitrate | AMX14, AMX15, AMX39, AMX47, AMX55, AMX56 | ||||
Reduction of nitrite | AMX9, AMX14, AMX55, AMX56, AMX57, AMX68 |
