Bacterial and methanogenic archaeal communities in mesophilic anaerobic co-digestion of fruit processing waste and waste activated sludge

摘要：

　　The methane production potential of two industrial solid wastes,fruit processing waste (FPW) and waste activated sludge (WAS) were investigated in mesophilic CSTR co-digester,and microbial community of each sludge sample was investigated using MiSeq sequencing.The specific methane production (SMP) and volatile solid (VS) removal of the process kept stable,and methane production rate (MPR) reached to 1.09 L·L-1 day-1 at organic loading rate (OLR) of 3.23 kgVS·m-3·d-1 and retention time of 11 days.Bacterial communities were represented by phyla of Proteobacteria,Bacteroidetes,Firmicutes and Chloroflexi,and the dominant methanogenic microbes was Methanolinea.Genus of Thauera made a great contribution in the co-digestion of FPW and WAS Redundancy discriminant analysis (RDA) revealed that the richness of hydrogen-utilizing and methylotrophic methanogens was benefit for the increase of OLR and MPR.
