Sludge, anaerobic reactor, PGA-Al, PGA-Al+SBC, PGA-Fe, and PGA-Fe+SBC microbial diversity
Sludge was collected from Jinshan wastewater treatment plant (Fuzhou, China). The bacteria biomass was obtained from a mesophilic fed-batch reactor enriched with a mixture of WAS and uronic acids-degrading bacteria. PGA-Al, PGA-Al+SBC, PGA-Fe, and PGA-Fe+SBC are the experimental groups.
