Abstract

In this study, poplar processing residues was used as the sole substrate for composting, and the microbiological communities such as fungi and bacteria were analysed. Two most favourable fungal phyla Ascomycetes and Basidiomycetes and five kinds of fungal genus such as Aspergillus, Thermomyces, Rhizomucor, Rhizopus, Myceliophthora were mainly distributed (more than 80%) in the high temperature samples. As for the bacteria, Firmicutes, Actinobacteria and Proteobacteria were the three most advantageous phyla in the high temperature samples. At the same time, Geobacillus, Bacillus, Thermobispora and Sphingomonas were the dominant bacteria in the high temperature samples at the genus level.
