The present study was aimed to investigate the enzymatic hydrolysis of straw biomass using crude cellulase produced by Cellulosimicrobium MP1 isolated from gut of termite. The alkaline pretreated biomass reached maximum saccharification yield of 69.91 % at 50 ºC, hydrolysis time of 48 hours, substrate to liquid ratio of 2 g/100 mL, cellulase concentration of
37.5 U/g and pH of 5.5. Compared to repoted publications, this saccharification yield in this study was rather good. Further study is needed to determine the composition of reducing sugars in the hydrolysates.
