Cellulose is a linear polymer of glucose units linked together by β -1,4-glycosidic bonds and is found as a major component of plant biomass that is naturally degraded by cellulolytic fungi and bacteria. Cellulose hydrolysis to glucose is performed via the synergic action of three cellulolytic enzymes: endo-β-D-glucanase (EC 3.2.1.4), exo-β- Dglucanase (EC 3.2.1.91) and β-glucosidase (EC 3.2.1.21). Production of glucose from agro industrial waste which can be utilized to produce value added products such as bioethanol is center of attraction of this era. Although there are several reports of potent cellulose producer from wide variety of microorganisms, it is rare from Streptomyces, which is known as the major producer of commercial antibiotics. In an attempt to screen Streptomyces strains capable of producing several cellulolytic enzymes from many Streptomyces strains preserved in our laboratory, caroboxymethyl cellulose (CMC)-agar plate method was used. Out of 62 strains, we found cellulolytic activity produced by 61 strains. Thus, although qualitative, we can conclude that almost all (~98%) Streptomyces strains are producer of cellulolytic enzymes in CMC-agar media, which can give a significant insight in the related field.
