Network of communities based on OTUs in sludge cascade utilization, through alkaline pretreatment. Electron transfer in integrated system was conducted by part of the initial anode respiring bacteria (ARB) and part of the evolutive ARB, interacting with fermentative communities. M-a MEC fed with alkaline treated SFL, F-a Fermentative solution of alkaline pretreatment
