In this study, stems of crops, including straw of rice, stalk of corn and bagasse, were used as fermentation materials. The hydrolysis treatment effects of <i>Aspergillus fumigatus</i>, <i>Trichoderma viride</i> and <i>Bacillus subtilis</i> were compared via spectrophotometry. The results showed that the highest yield of ethanol was from bagasse with eventually volume fraction of ethanol in total was 6.285% volume fraction. The difference of yields between corn straw and rice straw was slightly, which were 6.200% and 6.195% respectively. Using 2% NaOH pretreating sugarcane bagasse, then using <i>Aspergillus fumigatus</i> to degradeat 28℃, 20-25 h fermentation of pretreated filtrate with defective yeast and <i>Aspergillus fumigatus</i> degradation solution, it can improve the degradation efficiency of the lignocellulose conversion.
