白蚁内源性纤维素酶基因资源研究进展

摘要

Energy shortage has become a global problem, and cellulose is the most abundant and renewable resource in nature. Termites have evolved the unique and efficient cellulose-digesting system, in which there are rich resources of cellulase and its genes. In recent years, the significance of endogenous cellulose-digesting system in termite has been recognized gradually, and the researches on the endogenous cellulase genes have been reported continuously. In order to improve the new control technologies of termite pests and to explore the cellulosic biomass for biofuels, the review provides the information for the cloning and expressions of termite endogenous cellulase genes.%能源短缺是人类关注的焦点问题之一，而纤维素是自然界最为丰富的可再生资源。白蚁已进化出了独特而高效的纤维素消化系统，具有丰富的纤维素酶及其基因资源，因而，近年来白蚁内源性纤维素消化体系的重要性被逐渐认识，不断有内源性纤维素酶基因的研究报道。为了进一步推动有害白蚁控制新技术的研发，以及纤维素生物质新能源的应用探索，综述了白蚁内源性纤维素酶基因克隆、表达等研究进展。
