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
