Abstract: Distiller′s grains(dried)contain a lot of cellulose.The cellulose is the main component of plant cell wall and not easy to be digested,which becomes a key problem in reuse of distiller′s grains.This study was conducted to evaluate the degradation capacity of white rot fungi against the cellulose in distiller′s grains.The results showed that the cellulose degradation rate reached up to 9.5%.It is indicated that the application of white rot fungi can improve the utilization value of the distiller′s grains.
