摘要: The microbial community composition and function of three self-heating maize straw composts were compared by integrated meta-omics. results revealed that the fungal communities primarily dominated phylum Ascomycota (>90%) regardless different nitrogen sources, which exclusively composed Thermomyces, a genus hemicellulose degraders. bacterial was affected addition as abundance Actinobacteria increased, while Proteobacteria Bacteroidetes decreased. Various hemicellulases cellulases detected in composts, major xylanase secreted Thermomyces lanuginosus always present, revealing it dominant fungus hydrolysis bacteria fungi might synergistically degrade lignocellulose. Thus, may develop simple stable structure species limited numbers under selective pressure high temperature starting materials.
