RAMIREZ, Pablo  and  COHA, Juana María. Enzymatic degradation of cellulose for thermophilic actinomycete: isolation, characterization and cellulolytic activity determination. Rev. peru biol. [online]. 2003, vol.10, n.1, pp.67-77. ISSN 1727-9933.

One hundred and forty five cellulolytic thermophilic actinomycete strains were isolated from 71 compost, soil, hay and dung samples. Streptomyces sp. (50,63%), Thermomonospora curvata (15,82%), T. chromogena (13,92%), and other species were identified. Endoglucanase, exoglucanase and b-glucosidase activities were evaluated from 10 cellulolytic actinomycete strains. Among these the Streptomyces sp. 7CMC10 strain showed the biggest activity levels corresponding to 20,14; 2,61 and 5,40 UI/mg of protein, respectively.

Keywords : Actinomycetes; cellulases; thermophilic; Streptomyces; Thermomonospora; biotechnology.
