The Use of Streptomyces capoamus Isolated from Caatinga in the Production and Characterization of Microbial Endoglucanase | Chapter 05 | Advances and Trends in Biotechnology and Genetics Vol. 3
Cellulases are hydrolases of great importance to industries, especially due to their ability to produce ethanol via hydrolysis of cellulolytic materials. Actinomycetes are the producers of these enzymes, particularly the genus Streptomyces sp. The present study is the first report on the production and characterization of cellulolytic complex secreted by Streptomyces capoamus, isolated from the rhizosphere soil of Caatinga. In selecting the microbial producers of cellulolytic complex in qualitative tests, 171 x micro organism showed the most expressive enzymatic index. Regarding the production time of the complex, fermentation was done for 7 days, with aliquots being taken every 24 h. Peak production was obtained during 48 h fermentation. It was done at 37°C and under an agitation of 180 rpm. It was noted also that the 171x micro-organism produced the enzyme in greater quantity. The experiment was done with the most significant actinomycetes (171x), optimal substrate concentration (c...
