A total of twenty-one strains were isolated from various soil sources under wood decaying matter, manure and vegetative fields in the campus of Mandalay Technological University, Mandalay, Myanmar. Among them, eight strains were confirmed as Actinomycetes according to the biochemical examinations, cultural morphology, microscopic morphology and colonial morphology. Their cellulolytic activity was screened by using different types of cellulose substrates such as cellulose powder, CMC powder, acid treated rice straw and base treated rice straw. Quantitative determination was done by DNS reducing sugar analysis method and strains M2, V2 and W1 showed best results in reducing sugar productivity of 0.0504mg/ml using 1% CMC, 0.2100mg/ml using 0.5% cellulose and 0.1596mg/ml using 2% rice straw treated with 2M NaOH respectively.
