Research on identification and cellulase liquid fermentation of new cellulase-producing Streptomyces

摘要

The screening and cellulase production study of cellulase production microorganisms was the basis for the purpose. CMC medium was used in this study to isolate cellulose degrading bacteria. As a result, six strains were obtained from the soil, one strains of which Streptomyces-2 had higher cellulase activities in the Liquid fermentation medium of Straw, which was 3.230U/mL. By morphological observation and physiochemical analysis, it was primarily classified as Streptomyces sp which study less. It provides a new species for the cellulase application in the field of bio-chemical. At the same time it provides a new way for the cellulase applied to microbial conversion for low-rank coal in the future.
