摘要
纤维素的资源化利用是当前研究的热点。微生物作为处理纤维素的一种手段,由于其对环境危害小,且能实现资源的再利用而越来越受到重视。阐述了国内外纤维素酶对纤维素降解机制的研究进展,高效纤维素降解菌的选育及其混合菌群构建的研究概况。弄清纤维素酶的作用机制是关键,此外分离和选育出针对不同行业的高效纤维素分解菌种,研究不同来源纤维素酶以及不同菌种之间的协同作用,弄清菌株与菌株之间的关系及其在降解发酵过程中的作用,以达到构建高效稳定的纤维素降解菌群的目的,从而为实现纤维素的资源化利用提供科学的基础保障。
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.
