Recent Advances in Microbial Degradation of Cellulose

Resource utilization of cellulose has become hot topic. Due to less damage to the environment and realization of resource recycling, microorganism, as a way of degrading cellulose, was given more and more emphasis. Progress on the mechanism of cellulose degradation by cellulase, selecting the efficient cellulose-degrading microorganism and construction of composite microbial system were summarized in this paper. The attention should be paid was fully comprehending mechanism of cellulase action, which was the key issue of research. Added to this, study on cellulose with separate sources and synergistic effect among strains, isolation and selection high efficient cellulose-decomposing strains aiming at different industries and figuring out the relationship between strains and its action during fermentation should be 1aid stress on. The above aspects were helpful for building efficient and stable cellulose-degrading strains and provided scientific base guarantee for resource utilization of cellulose.
