compared to initial sewerage sludge ( IS ) , enriched sludge without CMC addition ( ES ) exposed 69 % higher CH ( 4 ) yield and about 1 -fold enceinte anaerobiotic biodegradation of cellulose . In particular , bacterial and archaeal diversities in samples vaccinated with ES were importantly altered , with Ruminiclostridium and Methanobacterium as the predominant genera . Enriched goop with CMC add-on ( ESC ) displayed enhanced methane production at initial cellulose agitation but pointed
