• A field survey was carried out from April to October, 1992 in the Miyatoko Mire in Fukushima Prefecture, Japan, to determine the characteristics of the microbial community and cellulose decomposition rates in the peat soil. A total of 14 study sites were selected, including three types ; hummocks (type I), hollows covered with Sphagnum (type II), hollows and streams without Sphagnum (type III). The numbers of fungi (2-1, 000×10^4 CFU g^<-1>) and bacteria (8.5-9, 000×10^5 CFU g^<-1>) varied with the sites and sampling dates : seasonal fluctuations were especially high in hummocks. The numbers of cellulolytic fungi (4.7-300×10^4 CFU g^<-1>) and cellulolytic bacteria (1.5-9.2×10^5 CFU g^<-1>) also differed between sites. Cellulolytic fungi were predominant in the Sphagnum peat of type I, while cellulolytic bacteria were predominant in the peat soil of type III. Decomposition rates of cellulose filter paper for the 6 month period ranged from 0.01 to 0.83, and tended to be higher in the peat of type II than type I.
