Abstract Two effective cellulose decomposing fungi(NM1-1 and NM1-2) were isolated and screened in the Horqin Sandy Grassland. They were identified as Asperigillus pseudodeflectus and Fusarium oxysporum by morphological and rDNA-ITS molecular biological methods. Cloth decomposition rate affected by NM1-1 and NM1-2 were 15.69% and 16.91% in 30 days, respectively; and litter decomposing rate affected by NM1-1 and NM1-2 were 53.61% and 45.72% in 30 days, and the rates were 7.70 and 6.42 times higher than that without any microorganism, respectively. The CMC enzyme activity was significantly higher produced by NM1-1 and NM1-2 than the soil environment where they were isolated. Isolation and screening of effective cellulose decomposing fungi supplemented the soil functional microbe bank, accelerate litter decomposing rate and stimulate available nutrient input in the Horqin Sandy Grassland.
